For **storing** new memories, always use the `memory-tool` CLI via exec. -- **Apply**: Authenticate via `vault login -method=oidc`, then use `scripts/tg` (preferred β€” handles state decrypt/encrypt) or `terragrunt` directly. `scripts/tg` adds `-auto-approve` for `--non-interactive` applies. -- **New services need CI/CD** and **monitoring** (Prometheus/Uptime Kuma) -- **New service**: Use `setup-project` skill for full workflow -- **Ingress**: `ingress_factory` module. **Auth** (`auth` string enum, default `"required"` β€” fail-closed). Pick by asking "what gates the app?": - - `auth = "required"` β€” Authentik forward-auth gates every request. Use when the backend has **no built-in user auth** and Authentik is the only thing standing between strangers and the app (prowlarr, qbittorrent, netbox, phpipam, k8s-dashboard, any admin UI shipped without its own login). - - `auth = "app"` β€” the backend handles its own user authentication (NextAuth, Django, OAuth, bearer-token API, etc.); Authentik would only break it. No middleware attached; the app's own login is the gate. Examples: immich, linkwarden, tandoor, freshrss, affine, actualbudget, audiobookshelf, novelapp. **Functionally identical to `"none"`** β€” the distinct name exists to record intent at the call site. - - `auth = "public"` β€” Authentik anonymous binding via the dedicated `public` outpost (routes via `traefik-authentik-forward-auth-public` β†’ `ak-outpost-public.authentik.svc:9000`). Strangers auto-bound to `guest`; logged-in users keep their identity in `X-authentik-username`. **Only works for top-level browser navigation** β€” CORS preflight rejects XHR/fetch and automation can't replay the cookie dance. Audit trail, not a gate. - - `auth = "none"` β€” no Authentik, no own-auth claim. Use for Anubis-fronted content (Anubis is the gate), native-client APIs (Git, `/v2/`, WebDAV/CalDAV, CardDAV), webhook receivers, OAuth callbacks, and Authentik outposts themselves. - - **Anti-exposure rule** (the reason `"app"` exists): only pick `"app"` or `"none"` AFTER you've verified the app has its own user auth (`"app"`) OR the endpoint is intentionally public (`"none"`). Default is `"required"` so accidental omission fails closed. **Convention**: when using `"app"` or `"none"`, add a comment line above the `auth = "..."` line stating what gates the app or why it's public. **Enforced by `scripts/tg`**: every `tg plan/apply/destroy/refresh` runs `scripts/check-ingress-auth-comments.py` against the current stack and aborts if any `auth = "app|none"` line lacks the preceding `# auth = "": ...` comment. Stack-scoped β€” untouched stacks aren't blocked until they're next edited. - - **Anti-AI**: on by default when `auth = "none"` or `auth = "app"` (no Authentik to discourage bots); redundant on `"required"` and `"public"`. - - **DNS**: `dns_type = "proxied"` (Cloudflare CDN) or `"non-proxied"` (direct A/AAAA). DNS records are auto-created β€” no need to edit `config.tfvars`. Smoke-test target: `echo.viktorbarzin.me` (auth=public, header-reflecting backend). -- **Anubis PoW challenge** (`modules/kubernetes/anubis_instance/`): per-site reverse proxy that issues a 30-day JWT cookie after a tiny PoW solve. Use for **public, content-bearing sites without app-level auth** (blog, docs, wikis, static landing pages). Pattern: declare `module "anubis" { source = "../../modules/kubernetes/anubis_instance"; name = "X"; namespace = ...; target_url = "http://..svc.cluster.local" }`, then in `ingress_factory` set `service_name = module.anubis.service_name`, `port = module.anubis.service_port`, `anti_ai_scraping = false`. Shared ed25519 key in Vault `secret/viktor` -> `anubis_ed25519_key`; cookie scoped to `viktorbarzin.me` so one solve covers all Anubis-fronted subdomains. **DO NOT put Anubis in front of Git/API/WebDAV/CLI endpoints** β€” clients without JS can't solve PoW. **Replicas default to 1** because Anubis stores in-flight challenges in process memory; a challenge issued by pod A and solved against pod B errors with `store: key not found` (HTTP 500). Bumping replicas requires wiring a shared Redis store (TODO). For path-level carve-outs (e.g. wrongmove has `/` behind Anubis but `/api` direct, blog has `/net-diag.sh` direct), declare a second `ingress_factory` with `ingress_path = ["/"]` pointing at the bare backend service. Active on: blog (except `/net-diag.sh`), www, kms, travel, f1, cc, json, pb (privatebin), home (homepage), wrongmove (UI only). See `.claude/reference/patterns.md` "Anti-AI Scraping" for full layering. -- **Docker images**: Always build for `linux/amd64`. SHA-tag rule is being phased out β€” see `docs/plans/2026-05-16-auto-upgrade-apps-{design,plan}.md`. New model: CI pushes `:latest` (optionally also `:<8-char-sha>` for traceability), Keel polls and triggers rollouts. Cache-staleness concern from the old rule is resolved at the nginx layer (URL-split β€” manifests pass through, blobs cached). Until Phase 1 of the migration completes (per the plan), follow the SHA-tag rule for new services to match existing pattern. -- **Private registry**: `forgejo.viktorbarzin.me/viktor/` (Forgejo packages, OAuth-style PAT auth). Use `image: forgejo.viktorbarzin.me/viktor/:` + `imagePullSecrets: [{name: registry-credentials}]`. Kyverno auto-syncs the Secret to all namespaces. Containerd `hosts.toml` on every node redirects to in-cluster Traefik LB `10.0.20.203` (with `skip_verify = true`, since the node dials Traefik by IP but the cert is for `forgejo.viktorbarzin.me`) to avoid hairpin NAT. That redirect covers **kubelet pulls** only β€” in-cluster pods (notably Woodpecker buildkit build pods pushing images) resolve `forgejo.viktorbarzin.me` via a CoreDNS `rewrite name exact ... traefik.traefik.svc.cluster.local` (Corefile in `stacks/technitium/modules/technitium/main.tf`), since they do NOT use the node containerd mirror; without it, buildkit pushes intermittently timed out on the public-IP hairpin (added 2026-06-04, beads code-yh33). **Was `.200` until 2026-06-01** β€” Traefik's 2026-05-30 move to its dedicated `.203` left this redirect pointing at the now-dead `.200:443`, silently breaking every *fresh* forgejo pull (cached images kept running, so it stayed hidden until a new image tag was pulled). Redirect source lives in `modules/create-template-vm/k8s-node-containerd-setup.sh` (new nodes) and `scripts/setup-forgejo-containerd-mirror.sh` (existing nodes). Push-side: viktor PAT in Vault `secret/ci/global/forgejo_push_token` (Forgejo container packages are scoped per-user; only the package owner can push, ci-pusher cannot write to viktor/*). Pull-side: cluster-puller PAT in Vault `secret/viktor/forgejo_pull_token`. Retention CronJob (`forgejo-cleanup` in `forgejo` ns, daily 04:00) keeps newest 10 versions + always `:latest`; integrity probed every 15min by `forgejo-integrity-probe` in `monitoring` ns (catalog walk + manifest HEAD on every blob). See `docs/plans/2026-05-07-forgejo-registry-consolidation-{design,plan}.md` for the migration history. Pull-through caches for upstream registries (DockerHub, GHCR, Quay, k8s.gcr, Kyverno) stay on the registry VM at `10.0.20.10` ports 5000/5010/5020/5030/5040 β€” the old port-5050 R/W private registry was decommissioned 2026-05-07. -- **LinuxServer.io containers**: `DOCKER_MODS` runs apt-get on every start β€” bake slow mods into a custom image (`RUN /docker-mods || true` then `ENV DOCKER_MODS=`). Set `NO_CHOWN=true` to skip recursive chown that hangs on NFS mounts. -- **Node memory changes**: When changing VM memory on any k8s node, update kubelet `systemReserved`, `kubeReserved`, and eviction thresholds accordingly. Config: `/var/lib/kubelet/config.yaml`. Template: `stacks/infra/main.tf`. Current values: systemReserved=512Mi, kubeReserved=512Mi, evictionHard=500Mi, evictionSoft=1Gi. -- **Node OS disk tuning** (in `stacks/infra/main.tf`): kubelet `imageGCHighThresholdPercent=70` (was 85), `imageGCLowThresholdPercent=60` (was 80), ext4 `commit=60` in fstab (was default 5s), journald `SystemMaxUse=200M` + `MaxRetentionSec=3day`. -- **Sealed Secrets**: User-managed secrets go in `sealed-*.yaml` files in the stack directory. Stacks pick them up via `kubernetes_manifest` + `fileset(path.module, "sealed-*.yaml")`. See AGENTS.md for full workflow. -- **CRITICAL β€” Update docs with every change**: When modifying infrastructure (Terraform, Vault, networking, storage, CI/CD, monitoring), you MUST update all affected documentation in the same commit. Check and update: `docs/architecture/*.md`, `docs/runbooks/*.md`, `.claude/CLAUDE.md`, `AGENTS.md`, `.claude/reference/service-catalog.md`. Stale docs cause incident response failures and onboarding confusion. If unsure which docs are affected, grep for the service/resource name across all doc files. - -## Terraform State β€” Two-Tier Backend -- **Tier 0 (bootstrap)**: Local state, SOPS-encrypted in git. Stacks: `infra`, `platform`, `cnpg`, `vault`, `dbaas`, `external-secrets`. These must exist before PG is reachable. -- **Tier 1 (everything else)**: PostgreSQL backend (`pg`) on CNPG cluster at `pg-cluster-rw.dbaas.svc.cluster.local:5432/terraform_state`. Native `pg_advisory_lock` for concurrent safety. Each stack gets its own PG schema. -- **Auth**: `scripts/tg` auto-fetches PG credentials from Vault (`database/static-creds/pg-terraform-state`). Humans use `vault login -method=oidc`, agents use K8s auth (role: `terraform-state`, namespace: `claude-agent`). -- **Tier 0 workflow** (unchanged): `git pull` β†’ `scripts/tg plan` β†’ `scripts/tg apply` β†’ `git push`. State sync via SOPS is transparent. -- **Tier 1 workflow**: `vault login -method=oidc` β†’ `scripts/tg plan` β†’ `scripts/tg apply`. No git commit needed β€” PG is authoritative. -- **Tier detection**: Defined in `terragrunt.hcl` (`locals.tier0_stacks`), `scripts/tg`, and `scripts/state-sync`. All three share the same list. -- **Fallback**: If PG is down, Tier 0 local state can bring it back (`scripts/tg apply` in `dbaas` stack). Tier 1 ops are blocked until PG recovers. -- **Tier 0 details**: Decrypt priority: Vault Transit (primary) β†’ age key fallback. Encrypt: both Vault Transit + age recipients. Scripts: `scripts/state-sync {encrypt|decrypt|commit} [stack]`. -- **Adding operator**: Generate age key (`age-keygen`), add pubkey to `.sops.yaml`, run `sops updatekeys` on Tier 0 `.enc` files. For Tier 1, only Vault access is needed. -- **Migration script**: `scripts/migrate-state-to-pg` (one-shot, idempotent) migrates Tier 1 stacks from local to PG. -- **Adopting existing resources**: use HCL `import {}` blocks (TF 1.5+), not `terraform import` CLI. Commit stanza β†’ plan-to-zero β†’ apply β†’ delete stanza. Canonical reason: reviewable in PR, plan-safe, idempotent, tier-agnostic. Full rules + per-provider ID formats in `AGENTS.md` β†’ "Adopting Existing Resources". - -## Secrets Management β€” Vault KV -- **Vault is the sole source of truth** for secrets. -- **`secret/viktor`** β€” go-to path for ALL personal secrets (135 keys). Contains every API key, token, password, SSH key, and config from the old terraform.tfvars. Check here first: `vault kv get -field=KEY secret/viktor`. -- **Auth**: `vault login -method=oidc` (Authentik SSO) β†’ `~/.vault-token` β†’ read by Vault TF provider. -- **Vault stack self-reads**: `data "vault_kv_secret_v2" "vault"` reads its own OIDC creds from `secret/vault`. -- **ESO (External Secrets Operator)**: `stacks/external-secrets/` β€” 43 ExternalSecrets + 9 DB-creds ExternalSecrets. API version `v1beta1`. Two ClusterSecretStores: `vault-kv` and `vault-database`. -- **Plan-time pattern**: Former plan-time stacks use `data "kubernetes_secret"` to read ESO-created K8s Secrets at plan time (no Vault dependency). First-apply gotcha: must `terragrunt apply -target=kubernetes_manifest.external_secret` first, then full apply. `count` on resources using secret values fails β€” remove conditional counts. -- **14 hybrid stacks** still keep `data "vault_kv_secret_v2"` for plan-time needs (job commands, Helm templatefile, module inputs). Platform has 48 plan-time refs β€” no migration possible without restructuring modules. -- **Database rotation**: Vault DB engine rotates passwords every 7 days (604800s). MySQL: speedtest, wrongmove, codimd, nextcloud, shlink, grafana, phpipam. PostgreSQL: health, linkwarden, affine, woodpecker, claude_memory, crowdsec, technitium. Excluded: authentik (PgBouncer), root users. **Apps that read a rotated secret only at startup** (env var / initContainer, not a hot-reloaded mount) MUST carry a Reloader annotation (`secret.reloader.stakater.com/reload: `) or they keep the stale password and silently fail DB auth on each rotation until manually restarted β€” matrix's Synapse `inject-db-password` initContainer hit exactly this (found via Loki 2026-06-05, ~12.9k auth-fail lines/hr); matrix has since migrated to tuwunel (RocksDB, no Postgres) on 2026-06-08 and is no longer in the rotation list above. Technitium uses a password-sync CronJob (every 6h) to push rotated password to the Technitium app config via API, disable SQLite + MySQL logging, check PG plugin is loaded, configure PG query logging (90-day retention), and disable SQLite on secondary/tertiary instances. -- **K8s credentials**: Vault K8s secrets engine. Roles: `dashboard-admin`, `ci-deployer`, `openclaw`, `local-admin`. Use `vault write kubernetes/creds/ROLE kubernetes_namespace=NS`. Helper: `scripts/vault-kubeconfig`. -- **CI/CD (GHA + Woodpecker)**: Docker builds run on **GitHub Actions** (free on public repos). Woodpecker is **deploy-only** β€” receives image tag via API POST, runs `kubectl set image`. Woodpecker authenticates via K8s SA JWT β†’ Vault K8s auth. Sync CronJob pushes `secret/ci/global` β†’ Woodpecker API every 6h. Shell scripts in HCL heredocs: escape `$` β†’ `$$`, `%{}` β†’ `%%{}`. -- **Platform cannot depend on vault** (circular). Apply order: vault first, then platform. Platform has 48 vault refs, all in module inputs β€” no ESO migration possible. -- **Complex types** (maps/lists like `homepage_credentials`, `k8s_users`) stored as JSON strings in KV, decoded with `jsondecode()` in consuming stack `locals` blocks. -- **New stacks**: Add secret in Vault UI/CLI at `secret/`, add ExternalSecret + `data "kubernetes_secret"` for plan-time, `secret_key_ref` for env vars. Use `data "vault_kv_secret_v2"` only if `data "kubernetes_secret"` won't work (e.g., first-apply bootstrap). -- **Backup CronJob**: `vault-raft-backup` uses manually-created `vault-root-token` K8s Secret (independent of automation). -- **Bootstrap (fresh cluster)**: Comment out data source + OIDC β†’ apply Helm β†’ init+unseal β†’ populate `secret/vault` β†’ uncomment β†’ re-apply. - -## Resource Management Patterns -- **CPU**: All CPU limits removed cluster-wide (CFS throttling). Only set CPU requests based on actual usage. -- **Memory**: Set explicit `requests=limits` based on VPA upperBound. Target: upperBound x 1.2 for stable services, x 1.3 for GPU/volatile workloads. -- **VPA (Goldilocks)**: Must be `Initial` mode (not `Auto`) β€” Auto conflicts with Terraform's declarative resource management. -- **LimitRange**: Tier-based defaults silently apply to pods with `resources: {}`. Always set explicit resources on containers needing more than defaults. Tier 3-edge and 4-aux now use Burstable QoS (request < limit) to reduce scheduler pressure. -- **Democratic-CSI sidecars**: Must set explicit resources (32-80Mi) in Helm values β€” 17 sidecars default to 256Mi each via LimitRange. `csiProxy` is a TOP-LEVEL chart key, not nested under controller/node. -- **ResourceQuota blocks rolling updates**: When quota is tight, scale to 0 then back to 1 instead of RollingUpdate. Or use Recreate strategy. -- **Kyverno ndots drift**: Kyverno injects dns_config on all pods. Every `kubernetes_deployment`, `kubernetes_stateful_set`, and `kubernetes_cron_job_v1` MUST include `lifecycle { ignore_changes = [spec[0].template[0].spec[0].dns_config] # KYVERNO_LIFECYCLE_V1 }` (use `spec[0].job_template[0].spec[0].template[0].spec[0].dns_config` for CronJobs). The `# KYVERNO_LIFECYCLE_V1` marker is the canonical discoverability tag β€” grep for it to locate every site. A shared Terraform module was considered but `ignore_changes` only accepts static attribute paths (not module outputs, locals, or expressions), so the snippet convention is the only viable path. Full rationale and copy-paste snippets in `AGENTS.md` β†’ "Kyverno Drift Suppression". -- **NVIDIA GPU operator resources**: dcgm-exporter and cuda-validator resources configurable via `dcgmExporter.resources` and `validator.resources` in nvidia values.yaml. -- **Pin database versions**: Disable Diun (image update monitoring) for MySQL, PostgreSQL, Redis. -- **Quarterly right-sizing**: Check Goldilocks dashboard. Compare VPA upperBound to current request. Also check for under-provisioned (VPA upper > request x 0.8). - -## CI/CD Architecture β€” GHA Builds + Woodpecker Deploy - -**Owned-app deploy model (build triggers the rollout β€” 2026-06-02):** For -self-hosted apps **we build** (Forgejo `viktor/` + Dockerfile + -`.woodpecker.yml`), the build pipeline ALSO drives the rollout β€” atomic + -deterministic, no wait for Keel's poll. Pattern (`build-and-push` tags `latest` -+ `${CI_COMMIT_SHA:0:8}`, then a `deploy` step): `kubectl set image -deployment/ =:${CI_COMMIT_SHA:0:8} -n ` + -`kubectl rollout status ... --timeout=300s`. The `woodpecker-agent` SA is -`cluster-admin`, so the `bitnami/kubectl` step needs no kubeconfig/RBAC (uses -its in-cluster SA). **Keel stays enrolled in parallel** as a redundant net -(finds the deployed SHA already running β†’ no-op). Requires the Deployment to -have `ignore_changes` on `…container[0].image` (KEEL_IGNORE_IMAGE) so CI -`set image` doesn't fight `terragrunt apply`.

At `0`, no model ever unloads and onnxruntime's CUDA arena (OCR's dynamic input shapes inflate it to ~10 GB) is held forever on the **time-sliced T4 it shares with llama-swap/frigate/immich-server** β€” which has no VRAM isolation, so immich-ml starved llama-swap (qwen3-8b) and silently broke recruiter-responder triage for ~5 h on 2026-06-02 (post-mortem `docs/post-mortems/2026-06-02-immich-ml-ttl-gpu-oom-recruiter.md`). TTL>0 lets idle models (OCR, face β€” AND CLIP) free VRAM. The TTL is a single GLOBAL knob (no per-model pin), so CLIP would also unload after 600s idle; the `clip-keepalive` CronJob (`*/5 * * * *`, same stack) pings the CLIP textual encoder so smart-search stays warm without pinning the ad-hoc models. **Smart search has a SECOND warmth layer in Postgres** (don't conflate it with the ML model): the ~665MB vchord `clip_index` must stay resident in PG `shared_buffers`, else an ANN probe that lands on an evicted list pays a ~1.8s cold storage read vs ~4ms warm. The `postStart` hook prewarms it ONCE at pod start and `pg_prewarm.autoprewarm` only re-warms at *startup*, so the index decays out of cache over days under job buffer-pressure (observed ~33% resident after 9d uptime β†’ slow context search, easily misattributed to the ML model).

Direct DB edits need a pod **recreate** to reload (config is cached at boot; only API-driven changes broadcast a reload). **Streaming bitrate is capped** to keep 4K playback smooth on the contended HDD and over remote uplinks: `ffmpeg.maxBitrate=20000k` + `preset=medium` + `transcode=bitrate` (set 2026-06-01 β€” was uncapped `maxBitrate=0` + `ultrafast` + `targetResolution=original`, which produced 77–264 Mbps 4K transcodes that stuttered for every client, local and remote, since even a single stream needs ~10–13.5 MB/s off the shared `sdc` spindle). 4K resolution is preserved (`targetResolution=original`); originals are NEVER modified β€” only the `encoded-video/` streaming copy. To re-apply transcode settings to EXISTING videos (config changes only affect new/missing ones): delete the offenders' `asset_file` rows `WHERE type='encoded_video'` (derived/regenerable β€” never touches originals) then run videoConversion `force=false` (admin Jobs API β†’ "Missing"); it regenerates them to the deterministic `.mp4` path at concurrency 1 (gentle on sdc).

Parse the extracted text - -UK payslips are laid out in a few common templates (Sage, Iris, QuickBooks, Xero, in-house ADP/Workday layouts). Common landmarks: - -- "Pay Date" / "Payment Date" / "Date Paid" β€” the date wages hit the account. Usually at the top or in a header box. -- "Tax Period" / "Period" / "Month" β€” e.g. "Month 1", "Week 12". -- Two numeric columns per line: "This Period" (or "Amount", "Current") and "Year to Date" (or "YTD"). **Always take the This Period column**, never YTD. -- Payments / Earnings block: "Basic Pay", "Salary", "Bonus", "Overtime", "Commission", "Holiday Pay". -- Deductions block: "Income Tax" / "PAYE", "National Insurance" / "NI" / "NIC", "Pension" / "Pension Contribution" / "Salary Sacrifice Pension", "Student Loan" / "SL", optional: "Union Dues", "Charity", "Season Ticket Loan", "Private Medical", etc. -- "Gross Pay" / "Total Gross" β€” sum of payments. -- "Net Pay" / "Take Home" / "Amount Payable" β€” the money actually paid. -- "Tax Code" β€” e.g. "1257L", "BR", "D0", "NT". -- "NI Number" / "National Insurance Number" β€” `AA123456A` format. Never invent one. -- "Employer" / "Company" β€” usually in the letterhead. "Employee" / "Name". -- Currency: almost always GBP / "Β£" for UK payslips. If the PDF is not in GBP or not a UK payslip, still return the numbers as-is but include a best-effort `currency` field. - -### Step 4. Map to the schema and emit JSON - -Rules that apply regardless of the caller's exact schema: - -- **Dates**: `pay_date` MUST be `YYYY-MM-DD`. If the PDF prints `12/03/2026`, interpret as `DD/MM/YYYY` (UK format) β†’ `2026-03-12`. If ambiguous (`01/02/2026`), prefer UK ordering. If impossible to determine a year, use the pay_period year. -- **Money fields**: emit as JSON numbers, not strings. Two decimal places are acceptable (`2450.17`). Strip `Β£`, commas, and trailing spaces. Negative values stay negative. -- **Missing numeric fields**: emit `0` (zero), not `null`, not an empty string, not `"N/A"`. -- **`other_deductions`**: an object mapping `{ "<label>": <number>, ... }` for any deduction that isn't one of the first-class fields in the schema (tax, NI, pension, student loan). Use the exact label from the payslip (e.g. `"Season Ticket Loan"`, `"Private Medical"`). If there are no other deductions, emit `{}` β€” NEVER `null` and NEVER omit the key. -- **Column discipline**: ALWAYS use the "This Period" column, NEVER the YTD column. If only one column exists, that's the period column. -- **Currency default**: `"GBP"` unless the payslip explicitly shows another currency symbol or ISO code. -- **No invented data**: If a field genuinely isn't on the payslip, use the documented default (`0` for money, `""` for strings, `{}` for objects). Do NOT make up names, NI numbers, tax codes, or employers. - -Follow the exact field names and types given in the prompt's schema. If the prompt's schema adds fields not listed above, produce them too using the same discipline. - -## Failure mode - -If the PDF cannot be read at all β€” unreadable base64, not a PDF, encrypted PDF with no text layer, no text-extraction tool available, or clearly not a UK payslip β€” emit a single JSON object: - -```json -{"error": "<short human reason>"} -``` - -Examples of acceptable error reasons: -- `"base64 did not decode to a valid PDF"` -- `"pdf has no extractable text layer (image-only scan)"` -- `"no pdf text extraction tool available (pdftotext/pypdf/pdfplumber all missing)"` -- `"document does not appear to be a UK payslip"` -- `"pay_date not found on document"` - -The caller treats the `error` key as a non-retriable parse failure. Do not include any other keys when emitting an error object. - -## Hard constraints β€” things you MUST NOT do - -1. **No network calls.** Do not curl, wget, dig, or otherwise talk to the network. Everything you need is in the prompt. -2. **No modifications to `/workspace/infra/**`.** Do not edit, write, or commit any file under the infra repo. The only file you may create is the scratch PDF at `/tmp/payslip.pdf` (and intermediate text dumps under `/tmp/`). -3. **No git operations.** No `git add`, `git commit`, `git push`, nothing. -4. **No kubectl, no terraform, no vault.** You are not an infra agent β€” you are a narrow extractor. -5. **No markdown in output.** No ` ```json ` fences, no preamble like "Here's the extraction:", no trailing notes. The ENTIRE final assistant message is exactly one JSON object. -6. **No verbose logging in the final message.** It is fine to run bash commands and see their output during processing, but your final assistant message is JSON and nothing else. -7. **No hallucinated fields.** If the payslip does not show a pension line, do not invent one. Use the documented default instead. - -## Output discipline β€” summary - -- Exactly one JSON object, UTF-8, no BOM. -- Keys match the schema the caller gave you. -- Numeric fields are JSON numbers, not strings. -- `pay_date` is `YYYY-MM-DD`. -- `other_deductions` is always present and is an object (possibly `{}`). -- Missing money β†’ `0`, missing string β†’ `""`, missing object β†’ `{}`. -- On unrecoverable failure, one JSON object with a single `error` key. - -That's the whole job.

If not, apply the second image update as a follow-up commit - -### Helm chart with atomic=true -Services like Authentik and Kyverno use `atomic = true`. If the Helm release fails, it auto-rolls back at the Helm level. The agent should still do its own verification, but can trust the deployment state. - -### Services without standard app label -Some services use different label selectors.

Bumped 2026-05-10 from `hours=168`. **Bumping requires `kubectl rollout restart deploy/ak-outpost-authentik-embedded-outpost`** β€” the gorilla session store binds the value once at outpost startup; the 5-min provider refresh logs `"reusing existing session store"` and skips rebuild. | -| `AUTHENTIK_SESSIONS__UNAUTHENTICATED_AGE` (server + worker) | `hours=2` | `server.env` + `worker.env` in `modules/authentik/values.yaml` | Anonymous Django sessions (bots, healthcheckers, partial flows) are reaped within 2h instead of the 1d default. | - -Notes: -- There is **no** `Brand.session_duration`; `UserLoginStage` is the only correct lever for authenticated session lifetime. -- Embedded outpost session storage: PostgreSQL table `authentik_providers_proxy_proxysession` in authentik 2025.10+ (PR #16628), but **only when `IsEmbedded()` returns true** (i.e. `Outpost.managed == "goauthentik.io/outposts/embedded"`). Our outpost record had `managed=null` until 2026-05-10, which silently kept it on the gorilla `FilesystemStore` at `/dev/shm` (TMPDIR) and re-exposed the 2026-04-18 mismatched-session-ID class on every pod restart. Fix landed 2026-05-10: see `authentik_outpost.embedded` in `authentik_provider.tf` and post-mortem `2026-04-18-authentik-outpost-shm-full.md`. -- The proxy outpost service has a known goauthentik 2026.2.2 bug (`internal/outpost/controllers/k8s/service.py:52`): for embedded outposts the controller sets the Service selector to `app.kubernetes.io/name=authentik` (the server pods), not `authentik-outpost-proxy`. We work around it via a `kubernetes_json_patches.service` patch on the outpost record (replaces `/spec/selector` with the outpost's own labels). Without this, endpoints are empty and Traefik forward-auth fails over to the Basic Auth realm `Emergency Access`. -- The standalone embedded-outpost deployment needs `AUTHENTIK_POSTGRESQL__{HOST,PORT,USER,PASSWORD,NAME}` env vars to reach the dbaas cluster β€” codified via `kubernetes_json_patches.deployment` envFrom the shared `goauthentik` Secret. The `app.kubernetes.io/component=server` pod label is also injected via JSON patch (matches the `component:server` half of the Service selector that the controller adds for embedded outposts). -- `ProxyProvider.remember_me_offset` stays UI-managed via `ignore_changes`. -- The Authentik provider's resource schema does **not** expose the `Outpost.managed` field. We rely on TF's "write only fields it knows about" semantic: the server-set `goauthentik.io/outposts/embedded` value is preserved across applies because Terraform never writes `managed`. Don't change the resource provider schema expectations without verifying this assumption holds. -- The `unauthenticated_age` env var is injected via `server.env` / `worker.env` (not `authentik.sessions.unauthenticated_age`) because we set `authentik.existingSecret.secretName: goauthentik`, which makes the chart skip rendering its own `AUTHENTIK_*` Secret. The `authentik.*` value block is therefore inert in this stack β€” anything new under `authentik.*` must use the `*.env` arrays instead. The same applies to the existing `authentik.cache.*`, `authentik.web.*`, `authentik.worker.*` blocks (currently inert; live values come from the orphaned, helm-keep-policy `goauthentik` Secret created by chart 2025.10.3 before `existingSecret` was introduced). - -## Upgrade Validation Checklist - -Run after **any** of these: -- Authentik chart version bump in `stacks/authentik/modules/authentik/main.tf` (the `version = "..."` line on `helm_release.authentik`). -- `goauthentik/authentik` Terraform provider version bump. -- Outpost pod recreation (kured reboot, eviction, manual `rollout restart`, scheduler move). - -The fragile surfaces are the `kubernetes_json_patches` and the `Outpost.managed` field β€” both rely on assumptions that can silently break across upgrades.

The new user just logs into `https://k8s.viktorbarzin.me` and -lands in the dashboard scoped to their namespace (`admin` on their namespace + -read-only on the namespace list & nodes for nav β€” no cross-tenant resource reads). - -> **Apply order for a new namespace-owner:** after the vault/rbac/woodpecker -> applies above, ALSO `cd stacks/k8s-dashboard && ../../scripts/tg apply` so the -> injector map picks up the new user.

If their workload lives -> in a DIFFERENT / pre-existing namespace (e.g. gheorghe's app is in `novelapp`, -> not his home `vabbit81`), that namespace's stack must ALSO grant their -> **dashboard SA** β€” `kind: ServiceAccount, name: dashboard-<user>, namespace: -> <home-ns>` β€” not just their OIDC `User` email (the dashboard uses the SA, and -> apiserver OIDC is blocked). See `stacks/novelapp/main.tf` `novelapp_owner_vabbit81` -> for the pattern (two subjects: User + SA). Best practice: set the user's -> `k8s_users` namespace to where their workload actually runs, so the home-ns -> auto-path covers them with no extra binding. - -The user can decrypt their stack's state with: -```bash -vault login -method=oidc # authenticates via Authentik SSO -scripts/state-sync decrypt NAMESPACE # decrypts only their stack -``` - -## What Gets Auto-Generated - -| Resource | Stack | Driven by | -|----------|-------|-----------| -| Kubernetes namespace | vault | `namespaces` list | -| Vault policy (`namespace-owner-{user}`) | vault | user key | -| Vault identity entity + OIDC alias | vault | user email | -| K8s deployer Role + Vault K8s role | vault | `namespaces` list | -| **SOPS Transit key** (`sops-state-{ns}`) | vault | `namespaces` list | -| **SOPS Vault policy** (`sops-user-{user}`) | vault | user key + namespaces | -| **SOPS identity group** (`sops-{user}`) | vault | user key | -| **SOPS group alias** (maps Authentik group) | vault | user key | -| RBAC RoleBinding (namespace admin) | rbac | `namespaces` list | -| RBAC ClusterRoleBinding (cluster read-only) | rbac | user role | -| ResourceQuota | rbac | `quota` object | -| TLS secret in namespace | rbac | `namespaces` list | -| Cloudflare DNS records | cloudflared | `domains` list | -| Woodpecker admin access | woodpecker | user key | - -## Checklist (Manual Flow) - -- [ ] Authentik: user added to `kubernetes-namespace-owners` group -- [ ] Authentik: user added to `sops-USERNAME` group (for SOPS state decrypt) -- [ ] Authentik: user added to `Headscale Users` group (if VPN needed) -- [ ] Vault KV: `k8s_users` entry added to `secret/platform` -- [ ] Vault stack applied β€” namespace + policy + identity + deployer role + SOPS Transit key + SOPS policy + SOPS group created -- [ ] RBAC stack applied β€” RBAC + quota + TLS created -- [ ] Woodpecker stack applied β€” admin list updated -- [ ] Verification: namespace, quota, policies (namespace-owner + sops-user), deployer role, Transit key all confirmed -- [ ] User notified with onboarding link diff --git a/.claude/skills/archived/authentik-oidc-kubernetes/SKILL.md b/.claude/skills/archived/authentik-oidc-kubernetes/SKILL.md deleted file mode 100644 index cee033f7..00000000 --- a/.claude/skills/archived/authentik-oidc-kubernetes/SKILL.md +++ /dev/null @@ -1,170 +0,0 @@ ---- -name: authentik-oidc-kubernetes -description: | - Configure Authentik as OIDC provider for Kubernetes API server authentication. - Use when: (1) setting up OIDC auth for kubectl with Authentik, (2) kube-apiserver - rejects OIDC tokens with "oidc: email not verified", (3) JWKS endpoint returns - empty {} despite provider being configured, (4) kubelogin fails with "claim not - present" for email, (5) redirect_uri mismatch errors during kubelogin browser auth, - (6) kube-apiserver static pod manifest changes don't take effect after restart. - Covers all gotchas discovered when integrating Authentik 2025.10.x with Kubernetes - 1.34.x using kubelogin (int128/kubelogin). -author: Claude Code -version: 1.0.0 -date: 2026-02-17 ---- - -# Authentik OIDC for Kubernetes API Authentication - -## Problem -Setting up Authentik as an OIDC identity provider for Kubernetes kubectl access -involves multiple non-obvious pitfalls that cause silent failures at different -stages of the authentication flow. - -## Context / Trigger Conditions -- Setting up multi-user kubectl access with OIDC -- Using Authentik as the identity provider and kubelogin (int128/kubelogin) as the kubectl plugin -- Any of these errors: - - `oidc: email not verified` - - `oidc: parse username claims "email": claim not present` - - `The request fails due to a missing, invalid, or mismatching redirection URI` - - JWKS endpoint (`/application/o/<app>/jwks/`) returns `{}` - - `Unauthorized` after successful browser login - -## Solution - -### Gotcha 1: Signing Key Must Be Assigned - -Authentik's OAuth2 provider does NOT assign a signing key by default.

When values are -changed, Helm may use `--reuse-values` behavior where it merges new values into existing -ones rather than doing a full template re-render.

The service is -completely unresponsive despite appearing healthy to Kubernetes. - -### Trigger Conditions -- Node was recently rebooted (check `kubectl get nodes` for age, or kured logs) -- Pod shows `Running 1/1` with 0 restarts (looks perfectly healthy) -- Service is unresponsive β€” Uptime Kuma or curl shows timeout/connection refused -- `kubectl exec <pod> -- ss -tlnp` shows **zero listening sockets** (the process started but is hung) -- Pod uses NFS volumes (inline `nfs {}` or PVC backed by NFS) -- Multiple pods across different namespaces all exhibit the same symptom simultaneously -- `kubectl describe pod` shows no warnings or errors β€” everything looks normal - -### Root Cause -When a node reboots, the NFS client mounts go stale. If the pod is rescheduled to the -same or different node before NFS fully recovers, the application process starts but -immediately hangs when it tries to access the NFS-mounted filesystem. The process is -stuck in an uninterruptible I/O wait (D state) but Kubernetes sees the container as -running because the PID exists and liveness probes (if any) may not exercise the NFS path. - -### Solution -Force-delete the affected pods to trigger a clean reschedule with fresh NFS mounts: - -```bash -# Identify hung pods β€” Running but no listening sockets -kubectl exec -n <namespace> <pod> -- ss -tlnp 2>/dev/null -# If output is empty or shows no expected ports, the pod is hung - -# Force-delete to skip graceful shutdown (hung process won't respond to SIGTERM) -kubectl delete pod -n <namespace> <pod> --force --grace-period=0 - -# The deployment controller creates a new pod with fresh NFS mounts -kubectl get pods -n <namespace> -w -``` - -For bulk remediation after a cluster-wide event: -```bash -# Find all pods with NFS volumes that might be hung -# Check each service's expected port β€” if ss -tlnp shows nothing, force-delete -for ns in calibre stirling-pdf send speedtest n8n paperless-ngx; do - pod=$(kubectl get pod -n $ns -o name | head -1) - sockets=$(kubectl exec -n $ns ${pod} -- ss -tlnp 2>/dev/null | wc -l) - if [ "$sockets" -le 1 ]; then - echo "HUNG: $ns/$pod (no listening sockets)" - kubectl delete ${pod} -n $ns --force --grace-period=0 - fi -done -``` - -### Verification -```bash -# New pod should have listening sockets -kubectl exec -n <namespace> <new-pod> -- ss -tlnp -# Should show the application's expected port (e.g., *:8080) - -# Service should respond -kubectl exec -n <namespace> <new-pod> -- curl -sI http://localhost:<port>/ -# Should return HTTP response -``` - -### Key Diagnostic Insight -The critical signal is **Running 1/1 but zero listening sockets**. Normal healthy pods -always have at least one listening socket for their application port. If `ss -tlnp` -returns nothing, the process is hung on a stale NFS mount, not crashed β€” that's why -Kubernetes thinks it's fine. - -### Prevention -- Add **liveness probes** that hit the application's HTTP endpoint (not just TCP connect): - ```hcl - liveness_probe { - http_get { - path = "/" - port = 8080 - } - initial_delay_seconds = 60 - period_seconds = 30 - timeout_seconds = 5 - } - ``` -- This ensures Kubernetes detects hung pods and restarts them automatically. - -## See Also -- **nfsv4-idmapd-uid-mapping** β€” All UIDs show as 65534 (nobody) inside containers.

Firewalls must allow UDP 443 inbound. -- Traefik automatically handles TLS for HTTP/3 using the same certs as HTTPS. -- The `Alt-Svc` header is sent on HTTP/2 responses to tell clients HTTP/3 is available. - Clients then upgrade to HTTP/3 on subsequent requests. -- For non-Cloudflare (direct DNS) domains, only the Traefik-side config is needed. -- Cloudflare handles its own HTTP/3 negotiation with end users; the origin connection - between Cloudflare and Traefik uses HTTP/1.1 or HTTP/2 (not HTTP/3). - ---- - -## UDP Cross-Namespace Routing - -### Problem - -Adding a custom UDP entrypoint (e.g., DNS on port 53) to Traefik v3 via Helm chart values -doesn't work out of the box. Traffic times out even though the Traefik pod listens on the -port internally. Two separate issues compound: - -1. The Helm chart defaults `expose` to `false` for custom entrypoints -- the port is never - added to the LoadBalancer Service -2. `allowCrossNamespace` defaults to `false` -- IngressRouteUDP in namespace A can't - reference a Service in namespace B - -### Context / Trigger Conditions - -- Traefik Helm chart v39.0.0+ (Traefik v3.x) -- Custom UDP entrypoint defined in `ports` values -- `IngressRouteUDP` referencing a service in a different namespace -- Symptoms: - - `kubectl get svc traefik` doesn't show your custom UDP port - - UDP traffic to the LoadBalancer IP times out - - Traefik logs show: `"udp service <namespace>/<service> is not in the parent resource namespace <traefik-namespace>"` - - `netstat -ulnp` inside Traefik pod confirms it IS listening on the port - -### Solution - -#### Fix 1: Expose the UDP port on the Service - -In the Helm values, add `expose = { default = true }` to the entrypoint: - -```hcl -# Terraform HCL -ports = { - dns-udp = { - port = 5353 - exposedPort = 53 - protocol = "UDP" - expose = { default = true } # <-- Required for custom entrypoints - } -} -``` - -```yaml -# Helm values YAML equivalent -ports: - dns-udp: - port: 5353 - exposedPort: 53 - protocol: UDP - expose: - default: true -``` - -Note: The built-in `web` and `websecure` entrypoints have `expose.default = true` by -default, but custom entrypoints do NOT. - -#### Fix 2: Enable cross-namespace CRD references - -In the Helm values, add `allowCrossNamespace = true` to the kubernetesCRD provider: - -```hcl -# Terraform HCL -providers = { - kubernetesCRD = { - enabled = true - allowCrossNamespace = true # <-- Required for cross-namespace IngressRouteUDP - } -} -``` - -```yaml -# Helm values YAML -providers: - kubernetesCRD: - enabled: true - allowCrossNamespace: true -``` - -This is required whenever an `IngressRouteUDP` (or `IngressRouteTCP`, `IngressRoute`) -references a Kubernetes Service in a different namespace. - -### Verification - -```bash -# 1. Verify the port appears in the Service -kubectl get svc -n traefik traefik -o jsonpath='{.spec.ports[*].name}' -# Should include your custom entrypoint name (e.g., "dns-udp") - -# 2. Check Traefik logs for cross-namespace errors -kubectl logs -n traefik -l app.kubernetes.io/name=traefik | grep "not in the parent resource namespace" -# Should return nothing after the fix - -# 3. Test the UDP service -dig @<traefik-lb-ip> example.com -``` - -### Example - -DNS forwarding through Traefik to Technitium DNS: -- IngressRouteUDP in `traefik` namespace routes `dns-udp` entrypoint to - `technitium-dns:53` in `technitium` namespace -- Without Fix 1: port 53 never exposed on LoadBalancer -- traffic can't reach Traefik -- Without Fix 2: Traefik rejects the route -- logs error every ~60 seconds -- With both fixes: DNS queries to LoadBalancer IP:53 -> Traefik -> Technitium - -### Notes - -1. **Debugging order matters**: Fix 1 (expose) must come first. Without the port on the - Service, you can't even test if the routing works. Fix 2 (cross-namespace) errors only - appear in Traefik logs, not as user-visible failures. -2. **`allowCrossNamespace` is a security consideration**: It allows any IngressRoute CRD - to reference services in any namespace. If this is too broad, consider using - `TraefikService` middleware or moving the IngressRouteUDP to the target namespace. -3. **Rolling update**: Changing `allowCrossNamespace` triggers a Traefik pod restart - (new CLI args). Changing `expose` only updates the Service (no pod restart needed). -4. **This applies to TCP too**: `IngressRouteTCP` with cross-namespace services needs the - same `allowCrossNamespace` setting. - ---- - -## Plugin Download Failure (Global 404) - -### Problem - -After a node maintenance operation (containerd restart, node drain/uncordon, etc.), -all Traefik-managed routes return 404. Services, Ingresses, and Middlewares all exist -and look correct, making this extremely confusing to debug. - -### Context / Trigger Conditions - -- ALL Traefik routes return 404 simultaneously (not just one service) -- Traefik pods are Running and Ready -- Ingress resources exist with correct annotations -- Middlewares exist in the correct namespaces -- TLS secrets exist -- Traefik startup logs contain: `Plugins are disabled because an error has occurred` -- Plugin download error: `unable to download plugin ... context deadline exceeded` -- Happened after a node restart, containerd restart, or network disruption - -### Root Cause - -Traefik downloads plugins (crowdsec-bouncer, rewrite-body, etc.) from -`plugins.traefik.io` on **every pod startup**. If the download fails (network -unreachable, DNS not ready, timeout), Traefik **disables ALL plugins entirely**. - -Since the `crowdsec` middleware is a plugin-based middleware referenced in virtually -every Ingress annotation (`traefik-crowdsec@kubernetescrd`), Traefik treats the -missing plugin middleware as a fatal routing error and returns 404 for every route -that references it -- which is typically all of them. - -### Solution - -```bash -# 1. Confirm the diagnosis - check Traefik startup logs -kubectl logs -n traefik -l app.kubernetes.io/name=traefik | head -20 -# Look for: "Plugins are disabled because an error has occurred" - -# 2.

Error loading content: flate: corrupt input before offset 5` -- Mobile apps (e.g., Home Assistant Companion) fail while browser works -- HA Companion app shows repeated `GET /?external_auth=1` requests (auth loop) -- WebSocket connections (`/api/websocket`) are very short-lived (seconds instead of minutes) -- HTTP 499 errors on API calls (client disconnects due to corrupted responses) -- Using `packruler/rewrite-body` plugin v1.2.0 with `monitoring.types = ["text/html"]` - -### Root Cause -Despite the `monitoring.types = ["text/html"]` filter, the plugin attempts to decompress -ALL responses before checking content type. When decompression fails on certain gzip -encodings, it corrupts the response body, breaking: -- WebSocket upgrade handshakes -- Authentication flows (HA Companion app's `external_auth` callback) -- Mobile app connectivity (while browser appears to work due to auto-reconnect) - -### Misleading Symptoms -- HTTP/3 (QUIC) may appear to be the cause because HTTP/3 requests show 499 errors. - This is a red herring -- the rewrite-body plugin corruption affects all protocols. -- WebSocket issues may look like a timeout or proxy configuration problem. -- The `monitoring.types = ["text/html"]` config suggests the plugin should only touch - HTML, but it still processes all responses for decompression before filtering. - -### Solution - -#### Step 1: Create a strip-accept-encoding middleware -Add a Traefik middleware that removes `Accept-Encoding` from requests, forcing -backends to send uncompressed responses that the plugin can safely process: - -```hcl -# In traefik/middleware.tf -resource "kubernetes_manifest" "middleware_strip_accept_encoding" { - manifest = { - apiVersion = "traefik.io/v1alpha1" - kind = "Middleware" - metadata = { - name = "strip-accept-encoding" - namespace = kubernetes_namespace.traefik.metadata[0].name - } - spec = { - headers = { - customRequestHeaders = { - "Accept-Encoding" = "" - } - } - } - } - depends_on = [helm_release.traefik] -} -``` - -#### Step 2: Add middleware to routes with rewrite-body -In the ingress factory middleware chain, add `strip-accept-encoding` BEFORE the -rewrite-body middleware: - -```hcl -var.rybbit_site_id != null ? "traefik-strip-accept-encoding@kubernetescrd" : null, -var.rybbit_site_id != null ? "${var.namespace}-rybbit-analytics-${var.name}@kubernetescrd" : null, -``` - -The order matters: strip-accept-encoding must come first so the request reaches -the backend without Accept-Encoding, and the uncompressed response then passes -through the rewrite-body plugin. - -### Verification (Compression Fix) -1. Check Traefik logs for absence of `flate: corrupt input` errors: - ```bash - kubectl logs -n traefik -l app.kubernetes.io/name=traefik --tail=200 | grep -i "flate\|rewrite-body" - ``` -2. Verify the middleware chain includes strip-accept-encoding before rybbit: - ```bash - kubectl get ingress -n <namespace> <name> -o jsonpath='{.metadata.annotations.traefik\.ingress\.kubernetes\.io/router\.middlewares}' - ``` -3. Test mobile app connectivity (HA Companion, etc.) - -### Notes (Compression) -- This affects ALL services using the rewrite-body plugin, not just HA -- The fix is applied conditionally: `strip-accept-encoding` is only added to the - middleware chain when `rybbit_site_id` is set, so services without analytics - are unaffected -- Both `ingress_factory` and `reverse_proxy/factory` modules need the fix -- Traefik may still compress responses to clients via its own compression middleware; - the strip only affects the backend request -- The plugin's `monitoring.types` filter works for deciding what to rewrite, but - decompression is attempted on all responses regardless - ---- - -## Problem 2: Silent Skip (Accept Header Mismatch) - -### Symptoms -- rewrite-body middleware is in the ingress middleware chain and shows status "enabled" in Traefik API -- `curl https://example.com/` returns original HTML with no injected content -- Browser shows injected content (rybbit script, trap links, etc.) -- No errors in Traefik logs -- the plugin silently skips processing -- `monitoring.types = ["text/html"]` is configured in the middleware spec -- Middleware chain order is correct (strip-accept-encoding before rewrite-body) - -### Root Cause -In the plugin source code, `SupportsProcessing()` checks the **request** `Accept` -header (not the response `Content-Type`) against `monitoring.types`: - -```go -func (r *Rewriter) SupportsProcessing(req *http.Request) bool { - accept := req.Header.Get("Accept") - for _, monitoringType := range r.monitoring.Types { - if strings.Contains(accept, monitoringType) { - return true - } - } - return false -} -``` - -It uses `strings.Contains(accept, "text/html")`. The curl default `Accept: */*` does -NOT contain the substring `text/html`, so the plugin returns false and skips all -processing. Browser requests include `Accept: text/html,application/xhtml+xml,...` -which does match. - -### Misleading Symptoms -- Appears as if the middleware isn't working at all -- May look like a middleware ordering issue or configuration error -- `kubectl get middleware` shows the resource exists with correct spec -- Traefik API (`/api/http/middlewares/`) shows the middleware as "enabled" -- Checking the rewrite-body regex patterns seems pointless since nothing is being processed - -### Solution -This is **working as designed** -- not a bug. The fix depends on context: - -#### For testing with curl -Add the `Accept` header to simulate a browser: -```bash -curl -s -H "Accept: text/html,application/xhtml+xml" https://example.com/ -``` - -#### For verifying injection is working -```bash -# Check for injected content (trap links, analytics, etc.) -curl -s -H "Accept: text/html,application/xhtml+xml" https://example.com/ \ - | grep -oE 'href="https://poison[^"]*"' - -# Check for rybbit analytics -curl -s -H "Accept: text/html,application/xhtml+xml" https://example.com/ \ - | grep -oE 'src="https://rybbit[^"]*"' -``` - -#### For programmatic clients that need injection -If a non-browser client needs to receive injected content, ensure it sends -`Accept: text/html` in its request headers. - -### Verification (Accept Header) -```bash -# Without Accept header -- no injection (expected) -curl -s https://example.com/ | grep -c "rybbit" -# Output: 0 - -# With Accept header -- injection works -curl -s -H "Accept: text/html" https://example.com/ | grep -c "rybbit" -# Output: 1 -``` - -### Notes (Accept Header) -- This behavior is independent of the compression issue (Problem 1 above) -- The check is on the **request** `Accept` header, not the **response** `Content-Type` -- `Accept: */*` does NOT match -- `strings.Contains("*/*", "text/html")` is false -- Real AI scrapers typically send browser-like Accept headers, so trap links will be - injected for them correctly -- API calls (which typically send `Accept: application/json`) are correctly skipped - ---- - -## See Also -- `traefik-helm-configuration` -- Traefik Helm chart configuration and entrypoints -- `ingress-factory-migration` -- Covers the ingress factory module that creates - rybbit analytics middlewares diff --git a/.claude/skills/cluster-health/SKILL.md b/.claude/skills/cluster-health/SKILL.md deleted file mode 100644 index 6772bf99..00000000 --- a/.claude/skills/cluster-health/SKILL.md +++ /dev/null @@ -1,454 +0,0 @@ ---- -name: cluster-health -description: | - Check Kubernetes cluster health and fix common issues.

Shuts down the VM in Proxmox -6. Resizes the disk (`scsi0`) by the given increment -7. Starts the VM and waits for SSH -8. Expands the filesystem inside the guest (auto-detects LVM vs direct partition) -9. Uncordons the node -10. Shows verification output (`df -h` and node status) - -### 4. Update Terraform (if needed) - -If you want Terraform to reflect the new disk size, update the VM definition in `main.tf` or `modules/create-vm/` so that a future `terraform apply` doesn't revert the change.

When resolving internal service names like -`redis.redis.svc.cluster.local` (4 dots < ndots:5), glibc tries all search domain -suffixes before the absolute name. This generates queries like: - -1. `redis.redis.svc.cluster.local.namespace.svc.cluster.local` (CoreDNS handles, NxDomain) -2. `redis.redis.svc.cluster.local.svc.cluster.local` (CoreDNS handles, NxDomain) -3. `redis.redis.svc.cluster.local.cluster.local` (CoreDNS handles, NxDomain) -4. `redis.redis.svc.cluster.local.yourdomain.lan` (CoreDNS **forwards to external DNS**, NxDomain) -5. `redis.redis.svc.cluster.local` (finally resolves) - -Step 4 is the problem: CoreDNS forwards `*.yourdomain.lan` queries to the external DNS -server, flooding it with junk NxDomain requests. With hundreds of pods making DNS lookups, -this generates tens of thousands of useless queries per day. - -## Context / Trigger Conditions -- DNS server (e.g., Technitium, Pi-hole, BIND) shows high NxDomain percentage (50%+) -- DNS cache hit rate is unexpectedly low -- DNS logs show queries ending in `*.svc.cluster.local.yourdomain.lan` -- CoreDNS Corefile has a server block forwarding `yourdomain.lan` to an external DNS -- Node resolv.conf has `search yourdomain.lan` (set by DHCP) -- Top DNS clients by query volume are Kubernetes node IPs (not pod IPs), because - CoreDNS forwards via NodePort and the source IP becomes the node IP - -## Solution - -### Step 1: Confirm the problem -Check DNS query logs for the pattern: -```bash -# Enable Technitium query logging temporarily -# API: /api/settings/set?token=TOKEN&enableLogging=true&logQueries=true&loggingType=File - -# Check for junk queries -kubectl exec -n technitium PODNAME -- grep "cluster.local.yourdomain" /etc/dns/logs/*.log -``` - -### Step 2: Add generic CoreDNS template regex (RECOMMENDED) - -Instead of creating specific catch-all blocks for each junk suffix pattern, add a single -`template` directive with a regex inside the `yourdomain.lan` server block. This catches -ALL multi-label junk queries (e.g., `*.cluster.local.yourdomain.lan`, -`*.yourdomain.lan.yourdomain.lan`, `www.cloudflare.com.yourdomain.lan`) in one rule: - -``` -yourdomain.lan:53 { - errors - template ANY ANY yourdomain.lan { - match ".*\..*\.yourdomain\.lan\.$" - rcode NXDOMAIN - fallthrough - } - forward . <your-dns-server-ip> - cache { - success 10000 300 6 - denial 10000 300 60 - } -} -``` - -**How it works**: The regex `.*\..*\.yourdomain\.lan\.$` matches any query with 2+ labels -before `.yourdomain.lan` β€” meaning only single-label queries like `idrac.yourdomain.lan` -fall through to the real DNS server. All junk multi-label queries get instant NXDOMAIN. - -**Important**: The `fallthrough` directive is required so that legitimate single-label -queries (which don't match the regex) continue to the `forward` plugin. - -#### Alternative: Specific catch-all blocks (DEPRECATED) - -The older approach used separate server blocks per junk suffix pattern: - -``` -cluster.local.yourdomain.lan:53 { - errors - template ANY ANY { - rcode NXDOMAIN - } - cache { - denial 10000 3600 - } -} -``` - -This requires adding a new block for each pattern and doesn't catch arbitrary junk queries -like `www.cloudflare.com.yourdomain.lan`. The generic regex approach above is preferred. - -### Step 3: Apply the CoreDNS ConfigMap -```bash -kubectl apply -f coredns-configmap.yaml -# CoreDNS auto-reloads via the `reload` plugin (default 30s) -``` - -### Step 4: Manage in Terraform (this cluster) -The CoreDNS ConfigMap is managed in `modules/kubernetes/technitium/main.tf` as -`kubernetes_config_map.coredns`. To import an existing ConfigMap: -```bash -terraform import 'module.kubernetes_cluster.module.technitium["technitium"].kubernetes_config_map.coredns' 'kube-system/coredns' -``` - -## Verification -1. Test that the template returns NXDOMAIN instantly: -```bash -kubectl run dns-test --rm -i --restart=Never --image=busybox -- \ - nslookup redis.redis.svc.cluster.local.yourdomain.lan 10.96.0.10 -# Should return NXDOMAIN immediately -``` - -2. Check DNS logs - no more `*.cluster.local.yourdomain.lan` queries to external DNS -3. NxDomain percentage on external DNS should drop significantly within an hour - -## Additional Fix: Enable DNS Cache Persistence -If the DNS server (Technitium) loses its cache on pod restart, enable `saveCache`: -``` -/api/settings/set?token=TOKEN&saveCache=true -``` -This prevents the cache hit rate from resetting to zero after every restart. - -## Notes -- The same `ndots:5` issue also causes `*.yourdomain.lan.yourdomain.lan` (double suffix) - and `*.yourdomain.me.yourdomain.lan` patterns β€” the generic regex catches all of these -- The top DNS client IPs will be the **node IPs** (not pod IPs) because CoreDNS forwards - via NodePort, and the source becomes the node's IP -- `ndots:5` is the Kubernetes default and shouldn't be changed cluster-wide as it breaks - short-name service resolution -- Individual pods can set `dnsConfig.options: [{name: ndots, value: "2"}]` to reduce - search domain lookups, but this is a per-pod opt-in -- Prometheus scrape targets using `.yourdomain.lan` hostnames should add a trailing dot - (e.g., `idrac.yourdomain.lan.:161`) to bypass ndots expansion entirely -- ExternalName services don't need trailing dots β€” the generic template regex handles them - -## See also -- `pfsense-dnsmasq-interface-binding` β€” Related: preserve client IPs for DNS port forwarding -- `crowdsec-agent-registration-failure` β€” another common K8s DNS-adjacent issue -- `loki-helm-deployment-pitfalls` β€” Loki deployment patterns diff --git a/.claude/skills/pfsense/SKILL.md b/.claude/skills/pfsense/SKILL.md deleted file mode 100644 index cd92a771..00000000 --- a/.claude/skills/pfsense/SKILL.md +++ /dev/null @@ -1,194 +0,0 @@ ---- -name: pfsense -description: | - Manage the pfSense firewall at 10.0.20.1 via SSH.

-## Workflow - -### 1. Research Phase - -**Input**: GitHub repository URL or project name - -**Actions**: -- Visit the GitHub repository -- Check the README for: - - Official Docker image (Docker Hub, ghcr.io, etc.) - - docker-compose.yml file - - Self-hosting documentation - - Required dependencies (PostgreSQL, MySQL, Redis, etc.) - - Environment variables needed - - Default ports - - Storage requirements - -**Find Docker Image Priority**: -1. Check official documentation for recommended image -2. Look in docker-compose.yml for `image:` directive -3. Check GitHub Container Registry: `ghcr.io/<org>/<repo>` -4. Check Docker Hub: `<org>/<repo>` -5. Check releases page for container images -6. Last resort: Build from Dockerfile (avoid if possible) - -**Classify Dockerfile State** (drives whether we contribute a PR back upstream later): - -| State | When | Action on deploy success | -|---|---|---| -| `image-used` | An official/community image worked (priority 1-5). | No upstream PR. Default case. | -| `used-as-is` | Upstream ships a Dockerfile; it built and ran fine. | No upstream PR. | -| `fixed-broken-upstream` | Upstream Dockerfile exists but fails to build / run; we patched it. | Open a `fix-dockerfile` PR after stability gate. | -| `written-from-scratch` | Upstream has no Dockerfile at all; we authored one. | Open an `add-dockerfile` PR after stability gate. | - -Record the chosen state and supporting metadata in `modules/kubernetes/<service>/.contribution-state.json`. When we author or fix a Dockerfile, also write `modules/kubernetes/<service>/files/Dockerfile`, `.dockerignore`, and `BUILD.md` (from `templates/Dockerfile.README.md`) β€” these travel with the upstream PR. - -```json -{ - "upstream_repo": "owner/name", - "dockerfile_state": "written-from-scratch", - "dockerfile_path_in_infra": "modules/kubernetes/<service>/files/Dockerfile", - "deploy_target_url": "https://<service>.viktorbarzin.me", - "image_tag": "registry.viktorbarzin.me/<service>:<sha>", - "image_size": "<MB>", - "base_image": "<e.g. python:3.12-slim>", - "dockerfile_shape": "multi-stage, non-root, linux/amd64", - "deploy_verified_at": null, - "contribution_pr_url": null -} -``` - -**Dockerfile quality bar** (when writing one ourselves β€” enforced before PR): -- Multi-stage build where it makes sense (Node, Go, Rust, Python with compiled deps). -- Explicit non-root `USER`. -- `HEALTHCHECK` when the app exposes a known endpoint. -- Minimal base image (alpine / distroless preferred; `-slim` otherwise). -- No secrets baked in; runtime config via `ENV`. -- `.dockerignore` that excludes `.git`, `node_modules`, test artifacts. - -**Extract Configuration**: -- Container port (default port the app listens on) -- Environment variables (DATABASE_URL, REDIS_HOST, SMTP, etc.) -- Volume mounts (what data needs persistence) -- Dependencies (database type, cache, etc.) - -### 2.

NFS Storage Setup (if service needs persistent data) - -**IMPORTANT**: NFS directories must exist and be exported on the NFS server BEFORE deploying the service.

Reads `.contribution-state.json`; skips unless state is `written-from-scratch` or `fixed-broken-upstream` and no `contribution_pr_url` is already recorded. -2. Upstream sanity checks: repo exists, public, not archived; default branch discoverable; for `written-from-scratch`, verifies a `Dockerfile` didn't land upstream while we were deploying; bails cleanly if an open PR from our fork already exists. -3. `POST /repos/<owner>/<name>/forks` β€” idempotent; waits up to 30s for the fork to be ready at `ViktorBarzin/<name>`. -4. `POST /repos/ViktorBarzin/<name>/merge-upstream` β€” keeps fork current with upstream default branch. -5. Creates branch `add-dockerfile` (or `fix-dockerfile`), timestamp-suffixed if that branch already exists with unrelated commits. -6. Commits `Dockerfile`, `.dockerignore`, `BUILD.md` via Contents API. Each commit message carries `Signed-off-by:` for DCO-enforcing repos. -7. Opens PR against upstream with body rendered from `templates/PR_BODY.md`. -8.

A request to the service's public URL returns a non-error HTTP response from the cluster - 2. The Terragrunt stack applies cleanly from a fresh checkout with no manual cluster intervention - 3. The NFS volume is mounted inside the running pod and a file written to it survives a pod restart - 4. Woodpecker CI pipeline exists and triggers on push to the service's directory -**Plans**: 2 plans -Plans: -- [ ] 01-01-PLAN.md β€” Create FastAPI backend app, Dockerfile, and build/push Docker image -- [ ] 01-02-PLAN.md β€” Update Terraform deployment, apply stack, verify NFS, add CI pipeline - -### Phase 2: F1 Schedule Subsystem -**Goal**: The system automatically fetches the full F1 race calendar and serves it as structured data β€” users can see all sessions for the current season with correct times. -**Depends on**: Phase 1 -**Requirements**: SCHED-01 -**Success Criteria** (what must be TRUE): - 1. The `/schedule` API endpoint returns all races for the current season with session types (FP1-3, Qualifying, Sprint, Race) and UTC-correct timestamps - 2. Schedule data persists to NFS and is served correctly after a pod restart without re-fetching the API - 3. APScheduler triggers a background refresh of schedule data at least once daily without manual intervention - 4. A race that has already occurred shows a "past" status and an upcoming race shows "upcoming" status -**Plans**: TBD - -### Phase 3: Extractor Framework and First Site -**Goal**: The extractor plugin system is in place and at least one site extractor returns a valid, live HLS URL β€” proving the end-to-end extraction architecture. -**Depends on**: Phase 2 -**Requirements**: EXTR-01, EXTR-02, EXTR-03 -**Success Criteria** (what must be TRUE): - 1. The extractor registry lists all registered site extractors and dispatches to the correct one by site key - 2. The first site extractor returns a working m3u8 URL that plays when pasted into VLC, including passing any CSRF or token requirements - 3. Background polling runs automatically on the APScheduler, re-extracts streams at a configured interval, and caches results in Redis with a TTL - 4. Adding a second extractor requires only creating a new class file and registering it β€” no changes to the dispatcher or other extractors - 5. Extractor failures are logged with enough detail to identify exactly which step failed (request, token parse, URL extraction) -**Plans**: TBD - -### Phase 4: Stream Health and Fallback -**Goal**: Only verified-live streams reach users, broken streams are flagged, and when multiple sources exist the system automatically tries the next one on failure. -**Depends on**: Phase 3 -**Requirements**: HLTH-01, HLTH-02, HLTH-03, EXTR-05 -**Success Criteria** (what must be TRUE): - 1. The `/streams` API endpoint only returns streams that have passed a HEAD/partial-GET liveness check within the last health-check interval - 2. A stream that returns a non-200 or empty playlist is marked as dead and excluded from the API response without manual intervention - 3. The `/streams` response includes bitrate and liveness metadata per stream so the frontend can display stream quality - 4. When configured with multiple sources for the same session, the API returns them in reliability-ranked order (most recently verified first) -**Plans**: TBD - -### Phase 5: HLS Proxy Core -**Goal**: The proxy layer converts raw CDN HLS URLs into browser-playable same-origin URLs with full CORS support β€” a stream URL from the extractor can be played in any browser via the proxy. -**Depends on**: Phase 4 -**Requirements**: PRXY-01, PRXY-02, PRXY-03 -**Success Criteria** (what must be TRUE): - 1. Fetching `/proxy?url=<master-m3u8>` returns an m3u8 where every URI at every level (master, variant, segment) points back through the `/relay` endpoint β€” zero requests escape to the original CDN domain - 2. A browser playing a proxied stream completes all preflight CORS checks without errors, including the `Range` header - 3. Segment relay streams bytes to the browser as chunked transfer with no full-segment buffering β€” peak memory per active stream stays under 5 MB - 4. The proxy correctly handles both master playlists (multi-variant) and media playlists (single-variant) without special-casing at the caller -**Plans**: TBD - -### Phase 6: CDN Token Lifecycle and Quality -**Goal**: Streams stay alive for full 2+ hour F1 sessions without user intervention, and users can select video quality when multiple variants are available. -**Depends on**: Phase 5 -**Requirements**: EXTR-04, PRXY-04, PRXY-05 -**Success Criteria** (what must be TRUE): - 1. A stream that has been playing for 90 minutes continues without interruption β€” the background token refresh loop re-extracts and updates the cached URL before the CDN token expires - 2. The `/streams` response exposes available quality variants (resolution labels) for streams that provide multi-variant playlists - 3. Selecting a different quality variant via the API returns a proxied URL for that specific variant stream - 4. Token refresh failures are logged and surface in stream health status without crashing the relay or affecting other active streams -**Plans**: TBD - -### Phase 7: Frontend Core β€” Schedule, Picker, and Player -**Goal**: Users can open the service in a browser, see the F1 session schedule, pick a live stream from the available sources, and watch it in an embedded player on the same page. -**Depends on**: Phase 6 -**Requirements**: FRNT-01, FRNT-02 -**Success Criteria** (what must be TRUE): - 1. The schedule page lists all upcoming and past sessions grouped by Grand Prix, with correct local-timezone display and live/upcoming/past badges - 2. Clicking a live session shows a stream picker with available sources labeled by site name and liveness status - 3. Selecting a stream loads and begins playing it in the embedded hls.js player without leaving the page - 4. The player recovers from transient network errors automatically and displays a clear error message only on unrecoverable failure - 5. The app is usable on a desktop browser without requiring any browser extension or plugin -**Plans**: TBD - -### Phase 8: Multi-Stream Layout -**Goal**: Users can watch multiple streams side by side simultaneously β€” for example, the main race feed alongside a specific driver onboard camera. -**Depends on**: Phase 7 -**Requirements**: FRNT-03 -**Success Criteria** (what must be TRUE): - 1. The user can add a second stream to the view and both play simultaneously in a split-screen layout without audio or video interference between streams - 2. The layout adapts gracefully when two streams are loaded β€” each player gets equal visible area and independent controls - 3. Removing one stream from the multi-stream view does not interrupt the other stream -**Plans**: TBD - -## Progress - -**Execution Order:** -Phases execute in numeric order: 1 β†’ 2 β†’ 3 β†’ 4 β†’ 5 β†’ 6 β†’ 7 β†’ 8 - -| Phase | Plans Complete | Status | Completed | -|-------|----------------|--------|-----------| -| 1.

Missing probes on databases (MySQL, PostgreSQL, Redis), ingress, auth. -- Files: All stacks (identified via grep: 14 instances of liveness/readiness out of 70+ services). -- Cause: Default Kubernetes behavior is to not restart unhealthy pods without probes; cascading failures silent. -- Improvement path: Add `livenessProbe`, `readinessProbe`, and `startupProbe` to all stateful services (databases, message queues, auth providers). Use TCP/HTTP probes appropriate to each service. - -**Pod Disruption Budgets Missing:** -- Problem: Only 2 services have PodDisruptionBudget resources (identified via grep). Node evictions (updates, failures) can cause service degradation. -- Files: All stacks (need comprehensive PodDisruptionBudget coverage). -- Cause: PDBs are optional; many assume single-replica stateless services won't need them. -- Improvement path: Add PDB with `minAvailable: 1` to all services with `replicas > 1`. For single-replica services, ensure they're marked as non-critical (lower PriorityClass) or accept downtime during node maintenance. - -**Resource Requests Sparse, Limits Missing:** -- Problem: Many services lack explicit resource requests/limits. Kyverno auto-generates defaults but CPU limits often too low for bursty workloads (Immich ML, Ollama, Ebook2Audiobook). -- Files: Multiple stacks (e.g., `stacks/immich/main.tf`, `stacks/ebook2audiobook/main.tf`, `stacks/ollama/main.tf`). -- Cause: Request/limit tuning requires load testing; defaults used instead. -- Improvement path: Run load tests on GPU workloads (Immich ML, Ollama) to determine sustained CPU/memory. Set requests to P50 usage, limits to P99. Monitor via Prometheus and adjust quarterly. - -**Large Terraform Modules (900+ lines):** -- Problem: `stacks/platform/modules/dbaas/main.tf` is 916 lines; `stacks/immich/main.tf` is 660 lines; others > 450 lines. -- Files: `stacks/platform/modules/dbaas/main.tf` (916 lines), `stacks/platform/modules/nvidia/main.tf` (658 lines), `stacks/platform/modules/kyverno/resource-governance.tf` (809 lines). -- Cause: Monolithic resource definitions; hard to navigate and test. -- Improvement path: Split large modules into sub-modules (e.g., `dbaas/` β†’ `mysql/`, `postgresql/`, `pgadmin/`, `backups/`). Use Terraform workspaces for per-database configuration. - -## Fragile Areas - -**Immich Machine Learning GPU Dependency:** -- Files: `stacks/immich/main.tf` (lines 380-450). -- Why fragile: GPU workload (`immich-machine-learning-cuda`) requires Tesla T4 on k8s-node1. If GPU becomes unavailable (hardware failure, driver issues), ML inference fails silently (no fallback). Single GPU point of failure. -- Safe modification: Add `nodeAffinity` to prefer GPU but allow non-GPU fallback (degraded mode). Implement health checks on GPU availability (`nvidia-smi` probe). Test GPU failure scenario before production use. -- Test coverage: No tests for GPU unavailability; assumes GPU always available. - -**Nextcloud Backup/Restore Procedures Manual:** -- Files: `stacks/nextcloud/main.tf` (backup.sh and restore.sh ConfigMaps). -- Why fragile: Backup/restore scripts are ConfigMap-based; no automation. Restoration requires manual `kubectl exec` and script execution. No tested recovery procedure. -- Safe modification: Implement automated backup via Velero or CSI snapshots. Test restore procedure monthly via staged environment. -- Test coverage: No automated backup validation; scripts untested. - -**NFS Dependency for Data Persistence:** -- Files: 126 references to NFS volumes across all stacks. -- Why fragile: All stateful data depends on NFS server at `10.0.10.15`. If NFS becomes unavailable, all services lose data immediately (no local caches). No fallback storage. -- Safe modification: Implement NFS client-side read caching (Linux NFS mount options `ac,acregmin=3600`). Monitor NFS availability via Prometheus alerts (Mount point offline). Test NFS failover procedure (if replica NFS exists). -- Test coverage: No chaos engineering tests for NFS unavailability. - -**Istio Injection Disabled Cluster-Wide:** -- Files: `stacks/real-estate-crawler/main.tf` (line 19): `"istio-injection" : "disabled"` on namespace labels. -- Why fragile: No service mesh observability. Debugging pod-to-pod communication requires manual tracing (tcpdump). No mutual TLS between services. -- Safe modification: Enable Istio on non-critical services first (e.g., realestate-crawler). Monitor resource overhead. Gradually roll out to production. -- Test coverage: No mTLS validation; assumes all pods on same network are trusted. - -**PostgreSQL Custom Image Not Tracked:** -- Files: `stacks/platform/modules/dbaas/main.tf` (line 717): `image = "viktorbarzin/postgres:16-master"`. -- Why fragile: Custom build at Docker Hub with PostGIS + PgVector extensions. No version tag; `:master` tag is mutable. Upstream extension versions unknown. -- Safe modification: Pin to semantic version (e.g., `:16.4-postgis3.4-pgvector0.8`). Build images locally with Dockerfile tracked in git. Test extension versions against application requirements. -- Test coverage: No tests for extension availability or version compatibility. - -## Scaling Limits - -**Single-Replica Critical Services:** -- Current capacity: Immich server (1 replica), PostgreSQL databases (1 replica), Redis (1 instance), Traefik (varies). -- Limit: Node failure causes immediate service outage. Kubernetes default takes 5+ minutes to reschedule pod. -- Scaling path: Increase critical service replicas to 3 (quorum). Add pod anti-affinity to spread across nodes. Implement PodDisruptionBudget with `minAvailable: 2`. - -**GPU Capacity Bottleneck:** -- Current capacity: 1 Tesla T4 GPU on k8s-node1. -- Limit: Immich ML + Ebook2Audiobook + Ollama all compete for single GPU. Queue time 10+ minutes for CPU-bound inference tasks. -- Scaling path: Add second GPU (e.g., T4 or RTX 3090) to k8s-node1. Implement GPU scheduling via NVIDIA GPU Operator. Monitor GPU utilization (target 70-80%). - -**NFS Storage Capacity:** -- Current capacity: `/mnt/main/` mounted on TrueNAS (size unknown; typically 4-8TB in home setups). -- Limit: Immich (image library), Calibre (ebooks), Dawarich (location history) grow unbounded. When storage full, writes fail; services degrade. -- Scaling path: Monitor NFS capacity monthly (`df -h`). Set up Prometheus alert at 80% capacity. Plan for annual storage growth based on user behavior (e.g., 100GB Immich/month). - -**MySQL/PostgreSQL Connection Pool:** -- Current capacity: PgBouncer at `dbaas/pgbouncer` provides connection pooling. Default pool size likely 100-200 connections. -- Limit: Many simultaneous connections (Nextcloud, Affine, Gramps Web, Authentik) can exceed pool. New connections queue or fail. -- Scaling path: Monitor PgBouncer pool utilization (Prometheus metric `pgbouncer_pools_used_connections`). Increase pool size if > 80% utilization. Consider read replicas for read-heavy workloads. - -**API Rate Limiting & Bandwidth:** -- Current capacity: Services exposed via Traefik ingress. No global rate limiting documented. -- Limit: External tools (Immich mobile app, ebook2audiobook processing) can spike bandwidth. DoS-like behavior possible. -- Scaling path: Implement Traefik rate limiting middleware (Prometheus-aware). Add Cloudflare rate limiting on public domains. Monitor egress bandwidth. - -## Dependencies at Risk - -**Redis Stack `:latest` Tag:** -- Risk: `stacks/platform/modules/redis/main.tf` uses `image = "redis/redis-stack:latest"`. Redis Stack is actively developed; breaking changes possible. -- Impact: Unexpected version upgrade could introduce incompatibilities with clients expecting specific command set or module versions. -- Migration plan: Pin to specific Redis Stack version (e.g., `:7.2-rc1`). Test version upgrades in staging first. Monitor Redis logs for deprecated command warnings. - -**Immich `:latest` or Floating Tag:** -- Risk: `stacks/immich/main.tf` pins to `v2.5.6` but Immich frequently releases patch versions. Database migrations can cause downtime. -- Impact: If Immich version upgrades without testing, database migrations could fail or hang (no rollback mechanism). -- Migration plan: Pin to specific patch versions (e.g., `v2.5.6`, not `v2.5`). Test Immich upgrades in staging first. Maintain backup before upgrading. - -**Unsupported MySQL 9.2.0:** -- Risk: `stacks/platform/modules/dbaas/main.tf` specifies `image = "mysql:9.2.0"`. MySQL 9.2 is a development version (RC status as of Feb 2026). -- Impact: RC versions not recommended for production. Stability issues, CVEs possible. No long-term support. -- Migration plan: Migrate to MySQL 8.4 LTS or 9.0 GA (stable). Test data migration first. Plan for gradual rollout. - -**Python Timeouts in Monitoring Scripts:** -- Risk: `stacks/platform/modules/nvidia/main.tf` uses hardcoded `timeout=10` for HTTP requests and subprocess calls. Slow network conditions will fail. -- Impact: GPU monitoring will fail if network is slow or unavailable. Silent failures possible. -- Migration plan: Implement exponential backoff and retry logic (e.g., `tenacity` library). Increase timeout to 30s for unreliable networks. Log timeouts for debugging. - -## Missing Critical Features - -**No Disaster Recovery Plan:** -- Problem: Backup procedures exist (Nextcloud, MySQL) but no tested recovery procedure. No runbook for cluster disaster. -- Blocks: If cluster data lost, recovery would be manual and time-consuming. No RTO/RPO defined. -- Impact: Data loss risk > 24 hours to recover. - -**No Secrets Rotation Policy:** -- Problem: SSH keys, API tokens, database passwords stored in git-crypt and tfvars. No automated rotation schedule. -- Blocks: If key leaked, manual intervention required to rotate across all services. -- Impact: Leaked credentials persist until discovery. - -**No Cross-Cluster Failover:** -- Problem: Single Kubernetes cluster on Proxmox. No HA cluster or backup cluster. -- Blocks: Cluster-wide failure (network partition, hypervisor crash) causes total outage. -- Impact: RTO > 1 hour (manual intervention to restart hypervisor or re-provision). - -## Test Coverage Gaps - -**No Infrastructure Testing:** -- What's not tested: Terraform applies, Helm charts, manifests only validated via `terraform plan`. No `terratest`, no functional tests of deployed services. -- Files: All stacks (no test files found). -- Risk: Typos, variable misconfigurations, missing dependencies not caught until production apply. -- Priority: High β€” add `terratest` to validate Terraform. Test critical paths (database connection, ingress routing). - -**No Chaos Engineering Tests:** -- What's not tested: Pod evictions, node failures, NFS unavailability, network partitions. -- Files: All stacks (no chaos tests found). -- Risk: Cascading failures and data loss scenarios not validated. Assumptions about resilience untested. -- Priority: High β€” run monthly chaos tests (Gremlin, Chaos Toolkit). Document recovery procedures. - -**No Backup Restoration Tests:** -- What's not tested: Nextcloud backups, MySQL backups. Restore procedures exist but never executed. -- Files: `stacks/nextcloud/main.tf`, `stacks/platform/modules/dbaas/main.tf`. -- Risk: Backups corrupt or unusable when needed. RPO > 24 hours if discovery slow. -- Priority: High β€” monthly restore-to-staging test. Automate backup validation. - -**No Security Scanning for Vulnerabilities:** -- What's not tested: Container images for CVEs, Terraform for security anti-patterns (hardcoded secrets, overpermissive RBAC). -- Files: All stacks, all container images. -- Risk: Known vulnerabilities deployed to production. No supply chain security. -- Priority: Medium β€” integrate Trivy/Snyk into CI/CD. Scan images weekly; alert on high CVEs. - ---- - -*Concerns audit: 2026-02-23* diff --git a/.planning/codebase/CONVENTIONS.md b/.planning/codebase/CONVENTIONS.md deleted file mode 100644 index f1598d19..00000000 --- a/.planning/codebase/CONVENTIONS.md +++ /dev/null @@ -1,192 +0,0 @@ -# Coding Conventions - -**Analysis Date:** 2026-02-23 - -## Naming Patterns - -**Terraform Files:** -- `main.tf` - Primary resource definitions and module calls -- `terragrunt.hcl` - Stack-specific Terragrunt configuration -- `variables.tf` - Variable declarations for a stack -- `providers.tf` - Generated by Terragrunt root `terragrunt.hcl` -- `backend.tf` - Generated by Terragrunt for state backend configuration - -**Terraform Variables:** -- snake_case for variable names: `var.tls_secret_name`, `var.dbaas_root_password` -- snake_case for resource names: `resource "kubernetes_namespace" "nextcloud"` -- snake_case for local values: `local.tiers` -- UPPERCASE for environment-like globals in shell: `KUBECONFIG_PATH`, `PASS_COUNT` - -**Resource/Module Names:** -- kebab-case for Kubernetes resources: `nextcloud`, `whiteboard`, `kms-web-page` -- Leading underscore for prefixed resource names (internal/private pattern): resource names with underscores are module-internal -- Descriptive names matching functionality: `kubernetes_namespace`, `kubernetes_deployment`, `helm_release` - -**Shell Functions:** -- snake_case for function names: `parse_args()`, `count_lines()`, `check_nodes()` -- CamelCase for utility color variables: `RED`, `GREEN`, `YELLOW`, `BLUE`, `BOLD`, `NC` - -**Go Package/Test Names:** -- Package-level test functions: `TestContainsVideoMarkers()`, `TestIsDirectVideoContentType()` -- Table-driven test pattern with struct fields: `name`, `body`, `ct`, `want` - -## Code Style - -**Terraform Formatting:** -- Use `terraform fmt -recursive` for consistent formatting -- No explicit linter/formatter config file (tflint/terraform-lint not present) -- Indentation: 2 spaces (standard Terraform convention) -- Multi-line strings use heredoc syntax: `<<EOT ...

Create `stacks/<service>/` directory -2. Add `terragrunt.hcl`: - ```hcl - include "root" { - path = find_in_parent_folders() - } - dependency "platform" { - config_path = "../platform" - skip_outputs = true - } - ``` -3.

In parent, call factory multiple times: - ```hcl - module "instance1" { - source = "./factory" - name = "instance1" - # ... other params - } - ``` -4. Example: `stacks/actualbudget/` has factory instantiated for viktor, anca, emo - -**New Platform Module:** -1. Create `stacks/platform/modules/<service>/` directory -2. Add `main.tf` with resources (Helm chart, namespace, ConfigMaps, etc.) -3. Add `variables.tf` or declare variables in `main.tf` -4.

-## File Patterns & Imports - -**Terragrunt Patterns:** -- Include root: `include "root" { path = find_in_parent_folders() }` -- Declare dependencies: `dependency "platform" { config_path = "../platform"; skip_outputs = true }` -- Variable access: `var.<name>` in `main.tf` (variables sourced from `terraform.tfvars`) - -**Kubernetes Resource Patterns:** -- Namespace per service: `kubernetes_namespace.<service>` with tier label -- Helm releases: `helm_release.<chart_name>` with `templatefile` for values -- Inline NFS volumes: `volume { name = "data"; nfs { server = "10.0.10.15"; path = "/mnt/main/<service>" } }` -- TLS injection: Every stack calls `module "tls_secret"` to populate namespace secret -

---- - -## ACTION ITEMS - -### Immediate (potential service impact) -1. **dashy** -- CPU throttled at 98% (490m/500m). Increase CPU limit or investigate high CPU usage. -2. **stirling-pdf** -- CPU throttled at 99.7% (299m/300m). Increase CPU limit. -3. **dbaas/mysql-cluster-0** -- Previously OOMKilled. Currently at ~1845Mi with 2Gi limit on mysql container (~90%). Monitor closely or increase limit. -4. **vpa/vpa-admission-certgen** -- ImagePullBackOff. Fix image reference. -5. **trading-bot-workers** -- 1901Mi across 6 containers, sentiment-analyzer at 2Gi limit. Verify not OOMing. - -### Medium Priority (resource waste or risk) -6. **kms/kms-web-page** -- Guaranteed QoS at 500m CPU / 512Mi, but only uses 0m/10Mi. Massive overprovisioning. -7. **ollama/ollama** -- Requests 4Gi memory but uses 11Mi (GPU model in VRAM). If not using CPU memory, reduce request. -8. **resume/printer** -- Requests 1Gi memory but uses 109Mi. Consider reducing. -9. **nvidia-driver-daemonset** -- No limits set, using 1168Mi. Standard for driver but worth noting. -10. **servarr/flaresolverr** -- At 58% memory (148Mi/256Mi). Trending toward limit. - -### Low Priority (optimization opportunities) -11. Multiple pods in the monitoring namespace have generous limits but low actual usage (node-exporters at 9-24Mi with 800Mi limits). -12. crowdsec-agent pods have Guaranteed QoS (req=limit) at 500m/250Mi but use only 3-13m CPU and 43-48Mi memory. -13. Many edge-tier pods using <10% of their memory limits -- VPA recommendations could help right-size. diff --git a/.planning/quick/resource-audit-terraform-definitions.md

**backend/extractors/**: One file per site; base class enforces interface. Adding a new site = add one file + register it. No change to core. -- **backend/proxy/**: Isolated from extraction. Proxy only knows about URLs β€” it does not care how they were found. -- **backend/schedule/**: Completely independent subsystem. Can fail without breaking stream delivery. -- **backend/health/**: Decoupled checker; stores results in cache, consulted by API on `/streams` requests. -- **frontend/**: Standard SvelteKit layout. Minimal β€” schedule + player, nothing else. -- **stacks/f1-streams/**: Single Terragrunt stack following existing pattern in repo. - ---- - -## Architectural Patterns - -### Pattern 1: Extractor Plugin Interface - -**What:** Each site extractor implements a fixed interface (`extract(session_hint) -> list[StreamURL]`). The registry maps site keys to extractor classes. The dispatcher iterates the registry, calls each extractor, aggregates results. - -**When to use:** Always β€” the number of sites will grow and their anti-scraping measures change independently. Isolation prevents one broken extractor from affecting others. - -**Trade-offs:** Slightly more boilerplate per site; but each extractor is testable in isolation and replaceable without touching shared code. - -**Example:** -```python -class BaseExtractor(ABC): - site_key: str # e.g. "siteA" - - @abstractmethod - async def extract(self, hint: SessionHint | None = None) -> list[StreamURL]: - """Return list of live stream URLs found on this site.""" - ... - -class SiteAExtractor(BaseExtractor): - site_key = "siteA" - - async def extract(self, hint=None) -> list[StreamURL]: - # 1. GET page, parse CSRF token from HTML - # 2. POST with token to get obfuscated JSON - # 3. Decode JS-obfuscated URL - # 4. Follow redirects to final .m3u8 - ... -``` - -### Pattern 2: Playlist Rewriting Proxy - -**What:** The proxy layer fetches the upstream m3u8 and rewrites every URL inside it (both master β†’ variant pointers, and variant β†’ segment pointers) to point back through `/relay?url=<base64-encoded-original>`. The client never contacts upstream directly. - -**When to use:** Always when proxying HLS β€” the player will follow URLs in the playlist; if those URLs point to the origin CDN, the proxy is bypassed for segment delivery. - -**Trade-offs:** Adds ~1 hop latency per segment request. For a private service with 1-5 users, this is negligible. Benefit: hides origin, enables header injection (e.g., `Referer`), unified player experience. - -**Example:** -```python -def rewrite_playlist(m3u8_text: str, base_url: str, proxy_base: str) -> str: - """Rewrite all URIs in an m3u8 to go through the proxy relay endpoint.""" - lines = [] - for line in m3u8_text.splitlines(): - if line and not line.startswith("#"): - # resolve relative URL, then encode through proxy - absolute = urllib.parse.urljoin(base_url, line) - proxied = f"{proxy_base}/relay?url={b64encode(absolute)}" - lines.append(proxied) - else: - lines.append(line) - return "\n".join(lines) -``` - -### Pattern 3: Background Polling with In-Memory Cache - -**What:** Extraction and health checking run as background tasks on a schedule (e.g., every 2 minutes). Results are stored in a shared in-memory dict with timestamps. The API layer reads from cache and returns immediately β€” no per-request extraction. - -**When to use:** Always β€” on-demand extraction per client request would be slow (2-10s per site) and would hammer the source sites. - -**Trade-offs:** Cache staleness window (default 2 min). Acceptable for live sports: streams stay stable once live. - -**Example:** -```python -# cache.py -_stream_cache: dict[str, CachedResult] = {} - -async def get_streams() -> list[StreamURL]: - if cache_is_fresh(): - return _stream_cache["streams"].data - # else trigger background refresh - ... -``` - ---- - -## Data Flow - -### Stream Discovery Flow (background) - -``` -[Cron trigger: every 2 min] - ↓ -[Extractor Registry] - ↓ (fan-out, concurrent) -[SiteA Extractor] [SiteB Extractor] [SiteN Extractor] - ↓ -[Raw stream URLs: list of .m3u8 candidates] - ↓ -[Health Checker: partial GET each URL] - ↓ (filter: only HTTP 200 + video/mpegURL content-type) -[Validated stream URLs] - ↓ -[Cache: store with timestamp + site metadata] -``` - -### Client Playback Flow (per request) - -``` -[User opens /watch in browser] - ↓ -[Frontend GET /api/streams] - ↓ -[Backend reads cache β†’ returns stream list (site, quality, label)] - ↓ -[User picks a stream] - ↓ -[Player requests: GET /proxy?url=<m3u8-url>] - ↓ -[Backend: fetch upstream m3u8, rewrite URIs β†’ return modified m3u8] - ↓ -[Player follows variant playlist: GET /proxy?url=<variant-m3u8>] - ↓ -[Backend: rewrite segment URIs] - ↓ -[Player fetches segments: GET /relay?url=<segment>] - ↓ -[Backend: upstream fetch, pipe bytes β†’ client] - ↓ -[Video plays in browser] -``` - -### Schedule Flow - -``` -[Cron: daily or on-demand] - ↓ -[Schedule Client: GET Jolpica API /ergast/f1/current.json] - ↓ -[Parse: races, session types, UTC timestamps] - ↓ -[Normalise: map to internal Session model] - ↓ -[Store: NFS JSON file + in-memory cache] - ↓ -[Frontend GET /api/schedule β†’ displays session list] -``` - -### Key Data Flows - -1. **Extraction β†’ Cache β†’ API β†’ Frontend**: All stream data originates from extractors, flows through the cache as the single source of truth, and is served read-only to the frontend. No frontend-triggered extraction. -2. **Client β†’ Proxy β†’ Upstream CDN**: The proxy is a pure pass-through relay. It does not store segments. Bytes from upstream go directly to client socket. -3. **Schedule API β†’ NFS**: Schedule data is written to NFS on refresh so the pod can serve it immediately on restart without waiting for the next API poll. - ---- - -## Component Boundaries - -| Component | Owns | Does Not Own | -|-----------|------|--------------| -| Extractor (per site) | How to get stream URL from that site | Health checking, caching, proxying | -| Health Checker | Liveness state of each URL | How the URL was found | -| Proxy / Relay | Rewriting m3u8 URIs, piping bytes | Authentication with upstream (that's extractor's job) | -| Schedule Subsystem | F1 session calendar data | Stream availability for a given session | -| Backend API | Serving current state to frontend | Fetching or refreshing state | -| Frontend | User interaction, player | Any backend logic | - ---- - -## Suggested Build Order (Phase Dependencies) - -The dependencies flow strictly upward β€” each layer depends only on the layer below it being stable: - -``` -Phase 1: Schedule Subsystem - ↓ (F1 data available) -Phase 2: Extractor Framework + First Site Extractor - ↓ (raw URLs available) -Phase 3: Health Checker - ↓ (validated URLs available) -Phase 4: Proxy / Relay Layer - ↓ (streams playable through service) -Phase 5: Frontend (schedule + player) - ↓ (end-to-end usable) -Phase 6: Additional Site Extractors - ↓ (stream coverage widened) -Phase 7: K8s Deployment (Terraform/Terragrunt stack) -``` - -**Rationale:** -- Schedule first: gives a testable data source with zero anti-scraping complexity. -- Extractor framework before specific sites: the base class and registry must exist before any site can plug in. -- Health checker before proxy: no point proxying dead streams; the checker filters the list fed to the proxy. -- Proxy before frontend: the frontend player needs a working `/proxy` endpoint to function. -- Frontend last of core: all backend components are independently testable via curl/httpie before a UI exists. -- Additional extractors after core is working: adding more sites is low-risk incremental work once the pattern is proven. -- Deployment last: deploy once the service works end-to-end locally; avoids debugging infra and app simultaneously. - ---- - -## Anti-Patterns - -### Anti-Pattern 1: On-Demand Extraction Per Client Request - -**What people do:** Trigger extraction when the user clicks "show streams" in the browser. - -**Why it's wrong:** Extraction takes 2-10 seconds per site (HTTP round trips, JS parsing, redirect following). With multiple sites, this is 10-30 seconds of wall time. Source sites may rate-limit aggressive bursts. Multiple concurrent users would multiply the load. - -**Do this instead:** Run extraction on a background schedule. Cache results. The API returns immediately from cache. The user sees streams in <100ms. - -### Anti-Pattern 2: Single Extractor Handles All Sites - -**What people do:** One big function with `if site == "A": ... elif site == "B": ...` branches. - -**Why it's wrong:** Sites change their obfuscation methods independently. A change to Site A's extraction logic can accidentally break Site B. Testing is impossible in isolation. Adding Site C requires modifying a shared file. - -**Do this instead:** One class per site, implementing a common interface. Changes to Site A's extractor never touch Site B's code. - -### Anti-Pattern 3: Buffering Segments in Memory Before Sending - -**What people do:** Download the entire `.ts` segment to memory, then serve it to the client. - -**Why it's wrong:** HLS segments can be 2-10 MB each. With multiple concurrent viewers, memory pressure grows quickly. Introduces unnecessary latency (client waits for full download before first byte). - -**Do this instead:** Pipe bytes from the upstream response directly to the client socket as they arrive (chunked transfer). The client starts receiving immediately, memory stays flat. - -### Anti-Pattern 4: Hardcoding Site URLs and Tokens in Extractor Logic - -**What people do:** Hardcode `BASE_URL = "https://site-a.example.com"` and referer/cookie values inside the extractor file. - -**Why it's wrong:** Sites change domains and anti-scraping parameters frequently. When a site moves, you have to find and edit code rather than config. - -**Do this instead:** Extractor reads its config (base URL, required headers, any known static tokens) from a config object injected at construction. The registry passes config to extractors at instantiation. - ---- - -## Integration Points - -### External Services - -| Service | Integration Pattern | Notes | -|---------|---------------------|-------| -| Jolpica F1 API (`api.jolpi.ca/ergast/f1/`) | REST GET, poll daily | No API key required; backwards-compatible Ergast endpoints; schedule data available | -| OpenF1 API (`api.openf1.org/`) | REST GET, poll as needed | No API key; 3 req/s rate limit; 2023+ data only; useful for session status (live/upcoming) | -| Upstream streaming sites (Site A, B, N) | HTTP GET/POST with session cookies, CSRF tokens | Per-site; no shared pattern; treated as black boxes by the framework | -| Upstream CDN (HLS segments) | HTTP GET with Range support | Proxy relays bytes; must forward `Referer` and sometimes `Origin` headers or CDN rejects | - -### Internal Boundaries - -| Boundary | Communication | Notes | -|----------|---------------|-------| -| Extractor β†’ Cache | Direct function call (write) | Extractors do not call the cache directly β€” the dispatcher aggregates results then writes once | -| API β†’ Cache | Direct read | Synchronous, O(1) | -| API β†’ Proxy | Not direct β€” frontend calls `/proxy` endpoint, which is part of the same backend process | Can be split into separate service later if needed | -| Proxy β†’ Upstream CDN | Outbound HTTP | Must preserve session headers; upstream CDN may check Referer/Origin | -| Schedule Poller β†’ NFS | File write (JSON) | On pod restart, reads NFS before first API poll | - ---- - -## Scaling Considerations - -This is a single-user or small-group private service. Scaling is not a primary concern, but here are the natural pressure points: - -| Scale | Architecture Adjustments | -|-------|--------------------------| -| 1-5 concurrent viewers | Single backend pod, in-memory cache, direct pipe relay β€” fully sufficient | -| 10-20 concurrent viewers | Same architecture; segment relay becomes the bandwidth bottleneck (each viewer streams independently) β€” add HLS caching proxy (nginx) in front of relay | -| 50+ concurrent viewers | Segment relay load increases linearly; consider a CDN or caching layer for segments; extraction/health remain unchanged | - -### Scaling Priorities - -1. **First bottleneck:** Outbound bandwidth on segment relay. Each viewer pulls full bitrate independently through the service. At private-use scale this is negligible (1-5 viewers). -2. **Second bottleneck:** In-memory cache invalidation if multiple pods deploy (stateless pods don't share cache). Solved by using existing cluster Redis instead of in-process dict β€” but unnecessary until horizontal scaling. - ---- - -## Sources - -- HLS specification: RFC 8216 (IETF) β€” playlist structure, master/media playlist relationship, segment mechanics (HIGH confidence) -- HLS proxy pattern: Apple Developer Documentation (conceptual), corroborated by yt-dlp extractor framework analysis (MEDIUM confidence) -- yt-dlp plugin architecture: github.com/yt-dlp/yt-dlp README + docs (MEDIUM confidence) -- OpenF1 API: openf1.org official page β€” endpoints, rate limits, data coverage (HIGH confidence) -- Jolpica F1 API: github.com/jolpica/jolpica-f1 β€” Ergast compatibility, availability (MEDIUM confidence) -- System composition for this domain: inference from domain patterns, corroborated by extractor tool analysis (MEDIUM confidence) - ---- - -*Architecture research for: Live stream aggregation and proxy service (F1)* -*Researched: 2026-02-23* diff --git a/.planning/research/FEATURES.md b/.planning/research/FEATURES.md deleted file mode 100644 index 3e2147c0..00000000 --- a/.planning/research/FEATURES.md +++ /dev/null @@ -1,215 +0,0 @@ -# Feature Research - -**Domain:** Live Stream Aggregation / Sports Stream Proxy Service -**Researched:** 2026-02-23 -**Confidence:** MEDIUM - ---- - -## Feature Landscape - -### Table Stakes (Users Expect These) - -Features users assume exist.

A scraped m3u8 URL from `site.com` cannot be fetched by a Svelte app on `f1.viktorbarzin.me`. Every user-facing stream URL must route through the proxy backend. This is a hard architectural dependency, not an option. -- **Stream health checker enables stream picker quality:** Without health checking, the picker shows dead links. Health checking must run before streams are displayed and periodically during live sessions. -- **Automatic extraction trigger depends on schedule:** The scheduler must know when sessions start. Schedule API integration is therefore the first thing to build β€” everything else gates on it. -- **Multiple quality options conflict with simple proxy:** If the source provides a multi-variant HLS playlist, the proxy must rewrite ALL variant URLs (not just the master manifest). Adds complexity to the proxy rewriting layer. -- **Fallback ordering conflicts with stateless proxy:** Tracking success history requires at least a lightweight persistence layer (e.g., Redis or SQLite). If staying fully stateless, fall back to health-check-only ordering. - ---- - -## MVP Definition - -### Launch With (v1) - -Minimum viable product β€” what's needed to validate the concept. - -- [ ] **F1 Schedule view** β€” Show upcoming/live sessions for the current season.

They are computed client-side by obfuscated JavaScript β€” the page HTML contains an encrypted or encoded config blob, and the actual HLS URL is assembled by executing that JS. A scraper that fetches the raw HTML page and runs a regex over it finds nothing. - -**Why it happens:** -Developers assume "the URL must be somewhere in the page source." They inspect the page in DevTools, see the URL in the network tab, and try to replicate what they observe β€” but miss that the URL was produced by JS execution, not served in the initial response. - -**How to avoid:** -- For each target site: trace the actual network request that fetches the m3u8 in browser DevTools (Network tab, filter by `.m3u8`). Identify the API endpoint that the JS calls to get the signed URL. Replicate *that* API call (often a JSON endpoint), not the page fetch. -- If the token is computed entirely client-side (e.g., via CryptoJS with a hardcoded key), implement the same algorithm in your extractor. Do not run headless browser β€” reverse-engineer the JS algorithm. -- Document which sites require JS execution vs. which expose a clean API endpoint. Sites often have a backend API that the JavaScript calls; scraping that API is faster and more stable than re-implementing the JS. - -**Warning signs:** -- Extractor returns empty results on a page you can watch in the browser -- Network tab shows the m3u8 URL appearing only after JavaScript fires an XHR/fetch call -- Page HTML contains a large base64 blob or heavily obfuscated JS variable (e.g., `var _0x1a2b = [...]`) - -**Phase to address:** -Extractor design phase (before writing a single extractor). Establish upfront: for each target site, determine if raw HTTP fetch is sufficient or if API reverse-engineering is required. - ---- - -### Pitfall 2: m3u8 Segment URLs Break When Proxied Through a Different Domain - -**What goes wrong:** -When you fetch an m3u8 playlist and serve it through your proxy, the segment URLs inside the playlist may be absolute URLs pointing to the original CDN. The browser (or HLS.js) follows those segment URLs directly, bypassing your proxy entirely. This means you cannot control access, cannot inject headers, and CORS blocks the segments if the CDN doesn't allow cross-origin requests from your frontend domain. - -**Why it happens:** -HLS playlists can contain either absolute URLs (`https://cdn.example.com/seg001.ts`) or relative paths (`seg001.ts`). Most streaming CDNs use absolute URLs with signed tokens. Proxying only the m3u8 is insufficient β€” every segment URL must also be rewritten to route through your relay. - -**How to avoid:** -- When serving the m3u8 through your proxy, **rewrite all segment URLs** to point to your relay endpoint before sending the playlist to the client. Example: replace `https://cdn.site.com/segment001.ts?token=xyz` with `https://your-relay.domain/proxy/segment?url=<encoded-original-url>`. -- Your relay endpoint then fetches the original segment and streams it to the client. -- Handle multi-level playlists: master playlists (variant streams) reference child playlists which reference segments β€” rewrite at each level. - -**Warning signs:** -- Client-side CORS errors in browser console referencing the original CDN domain -- Network tab shows segment fetches bypassing your proxy after the m3u8 loads -- Some quality variants play but others don't (partial rewriting) - -**Phase to address:** -Stream relay/proxy phase. Must be designed before the first end-to-end stream test. - ---- - -### Pitfall 3: CDN-Signed Token URLs Expire Mid-Stream - -**What goes wrong:** -Many CDNs sign stream URLs with a short-lived token (often 5–30 minutes). The m3u8 playlist URL itself may be signed, and so may each segment URL. A user who starts watching near the token expiry time will get a working stream for the first few segments, then receive 403 Forbidden errors as the token expires mid-playback. - -**Why it happens:** -Developers test stream extraction, confirm the URL works, and ship it β€” without accounting for token TTL. The token was valid at extraction time but expires before or during playback. Live streams compound this: the m3u8 playlist updates every few seconds and each update may contain newly signed segment URLs. If your relay cached an old playlist, segments within it are expired. - -**How to avoid:** -- Never cache m3u8 playlist files. Always fetch the live playlist from upstream on each client request. Cache only TS/m4s segments (which have longer or no expiry). -- When extracting the initial stream URL, record the extraction timestamp and the token TTL (if discoverable from response headers like `Cache-Control: max-age=N`). Re-extract before expiry. -- Implement a background refresh: when serving a stream, periodically re-run the extractor to get a fresh URL and pivot the relay to the new upstream without interrupting the client. -- Test expiry by extracting a URL and waiting 30 minutes before playing β€” a failing test here reveals token TTL issues. - -**Warning signs:** -- Stream plays for exactly N minutes then fails with 403 on segments -- Extracting a URL works in isolation but fails when embedded in the player after a delay -- Sites with Cloudflare or custom CDN always add `?token=` or `?sig=` parameters to segment URLs - -**Phase to address:** -Stream relay phase. The relay architecture must include a URL refresh loop from day one. - ---- - -### Pitfall 4: Per-Site Extractor Maintenance Burden Is Dramatically Underestimated - -**What goes wrong:** -Each target site is a custom engineering problem. Sites change their HTML structure, JavaScript obfuscation, API endpoints, or anti-bot measures without notice. A working extractor can break silently overnight. With 5 target sites, you effectively have 5 separate maintenance tracks. Expecting "set and forget" behavior is the most common planning mistake in this domain. - -**Why it happens:** -Developers build an extractor, it works, and they move on. Sites then deploy a CDN update, change their frontend framework, or rotate their obfuscation keys. The failure is silent β€” no exception is raised, the extractor just returns no URL, and the user sees an empty player. - -**How to avoid:** -- Build a health check system that runs each extractor on a schedule (every 15 minutes during race weekends, every hour otherwise), logs success/failure, and triggers alerts on failure. -- Design extractors with failure visibility: log exactly which step failed (page fetch, URL parse, API call, etc.) so debugging is fast. -- Keep extractor logic isolated and testable: each extractor is a module that takes no inputs and returns a stream URL or raises an exception. Run integration tests against live sites on a schedule. -- Plan 1–2 hours of maintenance per extractor per month as baseline, more during site redesigns. - -**Warning signs:** -- No automated testing of extractors against live sites -- Extractor code tightly coupled to specific HTML element IDs or class names (breaks on any frontend change) -- No alerting when an extractor returns no URL - -**Phase to address:** -Extractor design phase. The monitoring/health-check system must be built alongside the first extractor, not added later. - ---- - -### Pitfall 5: Missing or Incorrect CORS Headers on the Relay Breaks Browser Playback - -**What goes wrong:** -HLS.js in the browser makes cross-origin requests to fetch m3u8 playlists and segment files. If your relay doesn't serve the correct CORS headers, every segment request fails with a CORS error. Even a single missing header (e.g., on `.ts` segment responses but not `.m3u8` responses) breaks the stream. - -**Why it happens:** -Developers test the relay with `curl` or server-to-server calls, where CORS is irrelevant. The relay works in isolation but fails when the browser's HLS.js player makes the requests. - -**How to avoid:** -- Set CORS headers on **all** relay endpoints: `Access-Control-Allow-Origin: *` (or your specific frontend domain), `Access-Control-Allow-Methods: GET, HEAD, OPTIONS`, `Access-Control-Allow-Headers: Range`. -- The `Range` header is critical: HLS.js often sends range requests for segments. If `Range` is not in `Allow-Headers`, preflight OPTIONS requests fail. -- Do not use wildcard `*` if you also send `Access-Control-Allow-Credentials: true` β€” that combination is invalid and browsers reject it. -- Test from the actual browser environment (or use a CORS testing tool) before calling any relay endpoint "done." - -**Warning signs:** -- Browser console shows `No 'Access-Control-Allow-Origin' header` errors -- Streams work when loaded directly in a `<video>` src but fail when loaded via HLS.js -- Preflight OPTIONS requests returning 405 Method Not Allowed - -**Phase to address:** -Stream relay phase, first integration test. - ---- - -### Pitfall 6: IP-Based Banning From Target Streaming Sites - -**What goes wrong:** -Streaming sites detect and ban server IP ranges because your relay sends requests from a datacenter IP (K8s node) with no residential IP characteristics. The extractor initially works from a developer laptop (residential ISP), then fails when deployed to the cluster because the server IP is blocked or fingerprinted differently. - -**Why it happens:** -Streaming sites use IP reputation databases. Cloud provider IP ranges (AWS, GCP, Hetzner, OVH, etc.) are pre-blocked or rate-limited on many streaming platforms. Your home cluster may or may not be in a residential IP range depending on your ISP. - -**How to avoid:** -- Test extractors from the same environment they'll run in (the K8s cluster) before committing to a site as a target. A site that works from your laptop may be blocked from the server. -- Use realistic HTTP headers: `User-Agent` matching a current browser, `Accept`, `Accept-Language`, `Accept-Encoding` headers that match a real browser session. Missing or mismatched headers are a primary signal. -- Include `Referer` headers matching the expected source page. Many CDNs check that the referer is the streaming site itself before serving signed URLs. -- Rotate request patterns if hitting the same site repeatedly: add random delays, avoid predictable polling intervals. - -**Warning signs:** -- Extractor works in local testing but returns 403/429 in deployment -- Sites return Cloudflare IUAM challenge pages (JS challenge) when scraped from the server IP -- Response body contains "Access Denied" or "Bot Detected" rather than the expected HTML - -**Phase to address:** -Extractor design phase. Test against the production network before finalizing site targets. - ---- - -## Technical Debt Patterns - -Shortcuts that seem reasonable but create long-term problems. - -| Shortcut | Immediate Benefit | Long-term Cost | When Acceptable | -|----------|-------------------|----------------|-----------------| -| Hardcode stream URL for the first race | Ship fast | Breaks immediately; no automation | Never β€” defeats the purpose | -| Use `BeautifulSoup` regex on entire page HTML | Simple implementation | Breaks on any frontend change; misses JS-rendered content | Only for static HTML pages with predictable structure | -| Cache m3u8 playlists at the relay | Reduce upstream requests | Serves expired segment URLs; stream breaks mid-playback | Never for live content | -| Single-threaded sequential extractor polling | Simple code | Can't handle concurrent users fetching different streams | Only in MVP with a single stream | -| Skip extractor health checks for MVP | Faster to ship | Silent failures, no visibility into broken extractors | Only if you have < 1 stream and check manually | -| Proxy all segments (relay mode) without segment caching | Correct behavior | High bandwidth usage; each viewer multiplies bandwidth | Only at low viewer count (< 5) | -| Use headless browser for all extractors | Handles all JS | Slow (3–10s per extraction), high memory, complex ops | Fallback for sites that truly cannot be handled otherwise | - ---- - -## Integration Gotchas - -Common mistakes when connecting to external services. - -| Integration | Common Mistake | Correct Approach | -|-------------|----------------|------------------| -| Target streaming sites | Fetch the HTML page and regex for the stream URL | Identify the actual API endpoint the site JS calls; hit that directly | -| Target streaming sites | Ignore cookies and session state | Maintain a cookie jar per site; some sites require a session cookie from the homepage before serving stream API | -| Target streaming sites | Send requests without `Referer` header | Always set `Referer` to the page that would normally contain the player | -| CDN segment URLs | Use the same signed URL for the full stream duration | Re-fetch the m3u8 on each playlist poll to get freshly signed segment URLs | -| OpenF1 API (race schedule) | Call live-data endpoints during a session on the free tier | Free tier allows only historical data; live data costs €9.90/month β€” use F1 calendar static JSON for schedule | -| OpenF1 API | Assume the API is official F1 data | OpenF1 is a third-party fan project, not affiliated with F1; data may lag or be incorrect | -| Ergast API | Expect stable availability in 2026 | Ergast deprecated their API in late 2024; use OpenF1 or the unofficial `api.formula1.com` instead | -| HLS.js player | Load the proxied m3u8 URL directly without error handler | Always attach `hls.on(Hls.Events.ERROR, ...)` with media error recovery; live streams have transient failures | -| HLS.js player | Assume autoplay works | Browser autoplay policies block unmuted video.

Go is more efficient at raw TCP proxying, but Python's yt-dlp/playwright ecosystem has no equivalent in Go β€” would require subprocess shelling out. Python wins for this use case. | -| yt-dlp (library) | yt-dlp (subprocess) | Never subprocess β€” library mode gives direct access to extractor info_dict, format selection, and cookie jars without shell overhead. | -| APScheduler | Celery | Celery requires a separate worker process + broker queue. APScheduler runs in-process. Overkill for 2 periodic jobs (schedule sync + pre-session scrape trigger). Use Celery only if scrape jobs need distributed execution across many workers. | -| hls.js | Video.js + @videojs/http-streaming | Video.js (v8.23.4) wraps hls.js internally but adds significant bundle overhead. Use hls.js directly in Svelte for minimal footprint and full control. | -| Redis (existing) | In-memory dict cache | In-memory cache is lost on pod restart (K8s). Redis provides persistence across restarts + shared state if you ever run multiple replicas. Already in cluster at no cost. | -| SvelteKit | Next.js / Nuxt | User preference is Svelte. SvelteKit's adapter-node works well in Docker/K8s. Bundle size advantage matters for embedded player page load time. | -| FastF1 | Direct Jolpica API calls | FastF1 adds built-in caching, retry logic, and Python models. Saves implementing Ergast-compatible parsing from scratch. jolpica-f1 API endpoint: `https://api.jolpi.ca/ergast/f1/<season>/races/` | -| Playwright (Python) | Selenium | Playwright is faster, has async API, and Chromium headless is more stable than Selenium's ChromeDriver setup. Playwright's `page.route()` lets you intercept XHR/fetch calls to capture stream URLs without loading full pages. | -| aiosqlite | PostgreSQL | PostgreSQL is overkill for single-node persistent schedule cache. SQLite with aiosqlite on NFS is fine for read-heavy, write-rare schedule data. If you need multi-pod writes, migrate to PostgreSQL. | - ---- - -## What NOT to Use - -| Avoid | Why | Use Instead | -|-------|-----|-------------| -| `requests` library | Synchronous only β€” blocks the event loop in async FastAPI handlers, causing stream proxy delays | `httpx` (drop-in async replacement with identical API style) | -| `youtube-dl` | Archived/unmaintained since 2021. yt-dlp is the maintained fork with 3x more extractors and weekly updates. Sites actively break youtube-dl. | `yt-dlp` | -| Selenium | Heavy (~500MB browser + driver), poor async support, ChromeDriver version pinning causes constant breakage in K8s | `playwright` (native async, auto-manages browser binaries) | -| Django | Sync-first ORM, not designed for long-lived streaming HTTP connections. FastAPI handles `StreamingResponse` for chunked relay natively. | `FastAPI` | -| FFmpeg-based re-encoding | Introduces CPU-intensive transcode step, adds latency, and is unnecessary β€” HLS segments are already in a playable format. Proxy segments as-is. | Direct HLS segment relay (fetch + stream through) | -| Tornado | Was the async Python standard before asyncio. Replaced by asyncio-native frameworks. Less ecosystem support. | `FastAPI` + `uvicorn` | -| Celery for simple scheduling | Requires Redis as broker + a separate worker pod. Two extra moving parts for tasks that can run in-process. | `APScheduler` (AsyncIOScheduler in FastAPI lifespan) | -| `m3u8` for full stream relay | Segment-by-segment proxying via Python is high-latency (Python overhead per segment fetch). Use HTTP redirect for public segments; only rewrite the playlist if segments require auth cookies. | Redirect to original segments where possible; only proxy if cookies are required | - ---- - -## Stack Patterns by Variant - -**If a site requires only cookie passing (no JS rendering):** -- Use `httpx` with cookie jar from initial login request -- Extract HLS URL from HTML with BeautifulSoup4 or regex -- No Playwright needed; much faster startup - -**If a site requires JavaScript execution to reveal the stream URL:** -- Use Playwright async API: `page.route()` to intercept XHR requests containing `.m3u8` URLs -- Use `page.evaluate()` to extract obfuscated CSRF tokens from JS context -- Cache the result in Redis with 20-minute TTL - -**If the HLS segments require authentication cookies:** -- Use m3u8 library to rewrite segment URLs β†’ point to proxy endpoint -- Proxy endpoint fetches segments with stored cookies and streams back bytes -- Required when segments have signed URLs or cookie gates - -**If yt-dlp has an extractor for the site:** -- Use `yt_dlp.YoutubeDL(opts).extract_info(url)` β€” returns `formats` list with direct HLS URLs -- Much simpler than custom Playwright extractor; always try yt-dlp first - ---- - -## Version Compatibility - -| Package | Compatible With | Notes | -|---------|-----------------|-------| -| FastAPI 0.132.0 | Pydantic 2.x | FastAPI 0.100+ requires Pydantic v2.

The recommended approach is a Python/FastAPI backend (async, streaming-capable) paired with a Svelte 5/SvelteKit 2 frontend. The backend has four distinct responsibilities that must be built in dependency order: schedule data retrieval, per-site stream extraction, stream health checking, and HLS proxy/relay. Each component is independently testable and the architecture enforces clean separation so that one broken extractor cannot affect the rest of the system. - -The core novelty of this product β€” and its hardest engineering challenge β€” is the per-site extractor subsystem. Each target streaming site uses custom anti-scraping measures (JS-rendered tokens, signed CDN URLs, IP-based blocking) that require a custom extractor per site, maintained independently. Existing tools (streamlink, yt-dlp) provide extraction patterns but not out-of-the-box support for private F1 streaming aggregators. The recommended approach treats yt-dlp as a first-pass extractor where it has coverage, and uses httpx + BeautifulSoup for custom extractors, with Playwright as a fallback only when JS execution is strictly required. - -The primary risks are: (1) extractor brittleness β€” sites change without notice and extractors silently fail, requiring a health-check monitoring loop from day one; (2) CDN-signed URL expiry mid-stream, requiring the proxy to never cache m3u8 playlists and to implement background URL refresh; (3) IP-based blocking from the K8s cluster β€” all extractors must be tested from production network before finalizing site targets. These risks are all addressable through upfront architectural decisions rather than retrofitting. - ---- - -## Key Findings - -### Recommended Stack - -The backend runs Python 3.13 on FastAPI 0.132.0 with uvicorn, using async throughout. yt-dlp 2026.2.21 is the primary extractor library (used as a Python library, not CLI). Playwright 1.58.0 (async Chromium) is the fallback for JS-rendered pages. httpx handles async HTTP for custom extractors. FastF1 3.8.1 provides the F1 race schedule via the Ergast-compatible jolpica API. APScheduler 3.11.2 runs periodic jobs (schedule refresh, extraction triggers) in-process without a separate worker. The existing cluster Redis is used for URL caching with TTL. SQLite via aiosqlite persists schedule snapshots to survive pod restarts. - -The frontend is Svelte 5.53.3 / SvelteKit 2.53.0 (user preference, also well-suited for minimal bundle size). hls.js 1.6.15 handles in-browser HLS playback via MSE. Tailwind CSS 4.2.1 provides styling via the Vite plugin (not PostCSS β€” breaking change from v3). All infrastructure deploys as a single Terragrunt stack following the existing repo pattern. - -**Core technologies:** -- **Python 3.13 + FastAPI 0.132.0**: Async-first, StreamingResponse for HLS relay, Pydantic models -- **yt-dlp 2026.2.21**: Primary stream extraction library β€” 1000+ extractors, Python library mode -- **Playwright 1.58.0**: JS-rendered page fallback β€” async API, `page.route()` for XHR interception -- **httpx 0.28.1**: Async HTTP for custom extractors and redirect chain following -- **FastF1 3.8.1**: F1 race schedule via jolpica API with built-in caching -- **APScheduler 3.11.2**: In-process async scheduler β€” avoids Celery overhead for 2 periodic jobs -- **hls.js 1.6.15**: Browser HLS playback via MSE β€” mandatory on non-Safari -- **Svelte 5 + SvelteKit 2**: Frontend framework (user preference, minimal bundle size) -- **Redis (existing cluster)**: Extracted URL cache with TTL β€” no additional infra cost -- **aiosqlite 0.22.1**: Schedule persistence to NFS β€” survives pod restarts - -**Do not use:** `requests` (sync, blocks event loop), `youtube-dl` (unmaintained), Selenium (poor async/K8s support), FFmpeg re-encoding (unnecessary latency), Celery (overkill for 2 jobs). - -### Expected Features - -Research confirms this product's novelty: no existing tool combines automated extraction from unofficial sources + browser-native proxied playback + schedule integration in a single web service. - -**Must have (table stakes):** -- F1 schedule view β€” show all session types (FP, Quali, Sprint, Race) with live/upcoming/finished indicator -- CORS-transparent HLS proxy β€” mandatory architectural requirement; streams cannot play in browser without it -- Per-site stream extractor β€” at least one working extractor proves the end-to-end pipeline -- Stream health checker β€” validates URLs before display; dead streams must not surface -- Stream picker β€” list available working streams, user clicks to load player -- Embedded HLS player β€” hls.js in Svelte, plays proxied m3u8 in-page -- Session countdown timer β€” client-side, zero backend cost -- Live session indicator β€” visual LIVE/UPCOMING/FINISHED badge - -**Should have (add after MVP validation):** -- Stream auto-refresh β€” re-extract every 5-10 min during live sessions -- Fallback stream ordering β€” health-check + reliability history drives ordering -- Source labeling in picker β€” show site name with each stream -- Race weekend overview β€” all sessions grouped per Grand Prix -- Additional site extractors β€” expand coverage once first extractor is stable - -**Defer (v2+):** -- Pre/post show and press conference coverage β€” complex site-specific session detection -- Multiple quality tiers β€” only if sources actually provide multi-variant playlists -- Proxy segment prefetch β€” high memory cost; only if buffering complaints emerge at scale -- Session reputation annotations β€” UX polish, not launch-critical - -**Explicit anti-features (do not build):** DVR/recording, chat, user accounts, stream transcoding, DRM support, telemetry overlay. - -### Architecture Approach - -The system has five clearly bounded layers: (1) Schedule Subsystem β€” polls jolpica/OpenF1 API, stores to NFS; (2) Extractor Layer β€” plugin-per-site pattern with a registry dispatcher, concurrent fan-out execution; (3) Health Checker β€” validates extracted URLs via partial GET, stores liveness state in cache; (4) Proxy/Relay Layer β€” rewrites m3u8 URIs at all levels (master β†’ variant β†’ segments) through `/relay`; (5) Svelte Frontend β€” schedule view, stream picker, hls.js player. All state flows from extractors through cache to the API; the frontend never triggers extraction directly. - -**Major components:** -1. **Extractor Registry** β€” maps site-key to extractor class; fan-out concurrent dispatch; one file per site -2. **Playlist Rewriter** β€” fetches upstream m3u8, rewrites all URIs to point through `/relay`; stateless -3. **Segment Relay** β€” pipes upstream `.ts`/`.m4s` bytes to client as chunked transfer; no buffering -4. **Schedule Subsystem** β€” daily cron via APScheduler, NFS persistence, jolpica API client -5. **Stream Health Checker** β€” background poller, HEAD/partial-GET on m3u8 URLs, results in Redis/memory cache -6. **Backend API (FastAPI)** β€” serves `/schedule`, `/streams`, `/proxy`, `/relay` endpoints; reads from cache only -7. **Svelte Frontend** β€” schedule page, watch page with stream picker and hls.js player - -**Critical patterns:** -- Extraction runs on background schedule, never on client request (on-demand extraction = 10-30s wait) -- One extractor class per site; common `BaseExtractor` interface; isolation prevents cross-site failures -- Proxy must rewrite m3u8 at every level β€” master, variant, and segment; partial rewriting breaks streams -- Segment relay must stream bytes chunked, never buffer entire segment in memory - -### Critical Pitfalls - -1. **JS-rendered tokens not in HTML** β€” Before writing any extractor, trace network traffic in DevTools to find the actual API endpoint the site JS calls. Replicate the API call, not the page fetch. Using Playwright is the last resort; most sites expose a clean JSON API once reverse-engineered. - -2. **m3u8 segment URLs bypass the proxy** β€” Rewrite all URLs in the playlist at every level (master β†’ variant β†’ segment). Verify with browser Network tab that zero requests reach the original CDN domain. - -3. **CDN-signed URLs expire mid-stream** β€” Never cache m3u8 playlists in the relay. Always fetch the live playlist from upstream on each poll. Implement background URL refresh that re-extracts before token TTL expires. - -4. **Extractor maintenance burden underestimated** β€” Sites break extractors without notice. Build health-check monitoring alongside the first extractor, not later. Alert on extractor failure within 5 minutes. Budget 1-2 hours/extractor/month for maintenance. - -5. **IP-based blocking from K8s cluster** β€” Test all extractors from the production cluster network before finalizing site targets. Datacenter IPs are pre-blocked on many streaming platforms. Simulate realistic browser headers (User-Agent, Referer, Accept-Language). - -6. **CORS missing on relay endpoints** β€” Set `Access-Control-Allow-Origin`, `Access-Control-Allow-Methods`, and `Access-Control-Allow-Headers: Range` on all relay responses. Missing `Range` header causes preflight failures for segment requests. Test from actual browser, not curl. - ---- - -## Implications for Roadmap - -The architecture's strict dependency chain dictates phase ordering. No phase can be skipped β€” each provides inputs required by the next. The recommended build order from ARCHITECTURE.md is confirmed by the pitfall analysis: the schedule subsystem must exist before extractors know when to run; extractors must work before the proxy has URLs to relay; the proxy must exist before the frontend has anything to play. - -### Phase 1: Foundation β€” Schedule, Infrastructure, and Extractor Framework - -**Rationale:** Schedule data is the trigger for everything downstream. Building the extractor framework (base class + registry) before writing any site-specific code prevents architectural lock-in. Both are low anti-scraping complexity β€” schedule uses a public API, framework is pure Python scaffolding. - -**Delivers:** Working F1 schedule API endpoint, extractor plugin system with registry, Terragrunt deployment stack, NFS mount, development environment - -**Addresses features:** F1 schedule view, live/upcoming/finished indicators, session countdown timer (frontend-only, depends on schedule data) - -**Avoids pitfalls:** Establishes upfront which extraction approach each target site requires (API endpoint vs JS reverse-engineering vs Playwright); tests extractors from production network before committing to sites; implements timezone-aware schedule storage - -**Research flag:** STANDARD β€” jolpica API is well-documented, Terragrunt stack pattern is established in repo - ---- - -### Phase 2: Extraction Pipeline β€” First Working Extractor - -**Rationale:** One end-to-end working extractor (raw URL β†’ validated stream URL) proves the extraction architecture before scaling to multiple sites. Health checker must be built alongside first extractor β€” not after β€” because silent failures are the primary operational risk. - -**Delivers:** First site extractor returning live HLS URLs, stream health checker (HEAD/GET validation), Redis caching with TTL, background polling scheduler - -**Addresses features:** Per-site stream extractor, stream health checker, stream auto-refresh (background polling) - -**Avoids pitfalls:** Extractor built with full failure visibility (logs which step fails); health-check alerts configured from day one; extractor tested from production K8s network before finalizing - -**Research flag:** NEEDS RESEARCH DURING PLANNING β€” specific target sites unknown; each site requires independent reverse-engineering; Playwright requirement depends on site-specific JS analysis - ---- - -### Phase 3: Stream Proxy and Relay Layer - -**Rationale:** The proxy layer converts raw CDN URLs (which browsers cannot fetch cross-origin) into browser-playable same-origin URLs. This is the architectural blocker for the frontend β€” no proxy, no browser playback. Must be built before any UI work. - -**Delivers:** `/proxy` endpoint (m3u8 fetch + full URI rewrite at all levels), `/relay` endpoint (chunked segment pipe-through), CORS headers on all relay responses, URL refresh loop for token expiry - -**Addresses features:** CORS-transparent HLS proxy (mandatory for all browser playback), multiple quality options (variant playlist rewriting), stream picker (proxied URLs safe to expose to frontend) - -**Avoids pitfalls:** Rewrites m3u8 at master + variant + segment levels; never caches playlists; streams segments as chunked transfer (no memory buffering); CORS headers include `Range` header; relay endpoint is not publicly accessible (Traefik auth) - -**Research flag:** STANDARD β€” HLS spec (RFC 8216) and proxy patterns are well-documented; implementation is mechanical once architecture is understood - ---- - -### Phase 4: Frontend β€” Schedule, Picker, and Player - -**Rationale:** All backend components are independently testable via curl before the UI exists. The frontend is the final assembly step, not an intermediate one. Building it last means it integrates against a working backend rather than mocking everything. - -**Delivers:** SvelteKit app with schedule view, stream picker, embedded hls.js player, session countdown timer, live/upcoming/finished badges - -**Addresses features:** Embedded HLS player, stream picker, session countdown, live session indicator, race weekend overview (grouping sessions by Grand Prix) - -**Avoids pitfalls:** hls.js error handler attached from day one; autoplay muted by default; streams display with source label and liveness status; timezone displayed in browser local time - -**Research flag:** STANDARD β€” SvelteKit + hls.js integration is well-documented; component structure is straightforward given small scope - ---- - -### Phase 5: Coverage Expansion and Reliability - -**Rationale:** Once the full pipeline is proven end-to-end with one extractor, adding more sites is low-risk incremental work following the established pattern. Stream reliability features (fallback ordering, source labeling) are only meaningful once multiple sources exist. - -**Delivers:** Additional site extractors (2-3 more sites), fallback stream ordering by health-check recency, source labels in stream picker, extractor monitoring alerts (notification channel) - -**Addresses features:** Additional extractors, fallback stream ordering, source labeling, stream auto-refresh improvements - -**Avoids pitfalls:** Each new extractor reverse-engineered independently; health-check alerts tested by deliberate failure injection before each race weekend - -**Research flag:** NEEDS RESEARCH DURING PLANNING β€” each new target site requires individual analysis of extraction approach; cannot be planned generically - ---- - -### Phase Ordering Rationale - -- **Schedule first:** Public API, no anti-scraping complexity, required by extraction scheduler. Proves the Terragrunt stack without risking extractor failures. -- **Extractor framework before site-specific extractors:** Base class and registry must exist first; forces interface design before implementation. -- **Health checker with first extractor:** Silent failures are the top operational risk; monitoring must not be deferred. -- **Proxy before frontend:** The frontend's player cannot function without a working `/proxy` endpoint; building UI against a mock wastes time. -- **Frontend last of core phases:** All backend endpoints are curl-testable; UI is integration, not a prerequisite. -- **Additional extractors after core works:** Pattern is proven, risk is low, each site is independently scoped. - -### Research Flags - -Phases needing `/gsd:research-phase` during planning: -- **Phase 2 (Extraction Pipeline):** Target sites unknown; each requires independent DevTools session to determine extraction approach (API endpoint, JS algorithm, or Playwright). Cannot scope extractors without site-specific analysis. -- **Phase 5 (Coverage Expansion):** Each new target site is a fresh reverse-engineering problem. Budget per-site research before each extractor is scoped. - -Phases with standard patterns (skip research-phase): -- **Phase 1 (Foundation):** jolpica/OpenF1 API is public and documented. Terragrunt stack follows established repo pattern. Extractor base class is standard Python ABC. -- **Phase 3 (Proxy/Relay):** HLS spec is RFC 8216. Proxy rewriting pattern is well-documented in HLS-Proxy and yt-dlp literature. CORS mechanics are standard. -- **Phase 4 (Frontend):** SvelteKit + hls.js integration has clear documentation. Component scope is small. - ---- - -## Confidence Assessment - -| Area | Confidence | Notes | -|------|------------|-------| -| Stack | HIGH | All versions verified against PyPI and GitHub releases as of 2026-02-23. Version compatibility matrix confirmed. | -| Features | MEDIUM | Feature list is well-grounded; competitor analysis confirms novelty. OpenF1 API confidence is MEDIUM (third-party fan project, not official F1). | -| Architecture | MEDIUM | HLS spec and proxy mechanics are HIGH confidence (RFC 8216, Apple docs). System composition for this specific use-case is inferred from domain patterns. | -| Pitfalls | MEDIUM | yt-dlp/streamlink source analysis and HLS RFC are HIGH; streaming site anti-scraping behavior is LOW (sparse public documentation). | - -**Overall confidence:** MEDIUM - -### Gaps to Address - -- **Target site list not defined:** The research assumes a list of specific streaming sites to target but does not name them. Phase 2 cannot be scoped until specific sites are identified and reverse-engineered in a DevTools session. This is the largest planning gap. -- **OpenF1 live data cost:** OpenF1's live session data costs €9.90/month on free tier. Research recommends using the F1 calendar static JSON for schedule. Validate whether jolpica API provides sufficient real-time session status (live/upcoming) before finalizing the schedule integration approach. -- **Home ISP IP classification:** Whether the K8s cluster's home ISP IP is treated as residential or datacenter by streaming site IP reputation databases is unknown. Must test each target site from the cluster before committing. Recovery if blocked: residential proxy or VPN exit node. -- **Multi-variant playlist availability:** The multiple-quality feature depends on source sites providing multi-variant HLS playlists.

Default reading of the bare word "node" in this repo. -_Avoid_: "k8s node" (redundant), "host" (ambiguous). - -**PVE node** / **PVE host**: -The single physical Dell R730 running Proxmox; sole hypervisor and sole NFS server. There is exactly one. -_Avoid_: "server", "hypervisor", "Proxmox" alone when you mean the host. - -**Namespace tier**: -A namespace-prefix partition (`0-core-*`, `1-cluster-*`, `2-gpu-*`, `3-edge-*`, `4-aux-*`) driving PriorityClass, default resources, and ResourceQuota β€” generated by **Kyverno policy** from the namespace name. Orthogonal to **State tier**. -_Avoid_: "Service tier" (the partition is on the namespace, not the Service); collapsing Namespace tier with State tier β€” they are different axes. - -**Kyverno policy**: -The convention engine of the cluster β€” a ClusterPolicy or Policy resource that mutates/generates/validates on admission. Owns Namespace tier limits/quotas, `dns_config` injection on every pod-owning workload, Forgejo pull-credential sync across namespaces, TLS-secret replication. When the repo says "this happens automatically", a Kyverno policy is usually the actor. -_Avoid_: bare "policy" (overloaded with Vault, RBAC, NetworkPolicy). - -**Critical-path Service**: -One of {Traefik, Authentik, CrowdSec LAPI, PgBouncer, Cloudflared} β€” replicas β‰₯3, PDB enforced, monitored independently. -_Avoid_: "core service" (collides with the `0-core-*` Namespace tier name). - -**Namespace-owner**: -A non-admin identity declared in `secret/platform β†’ k8s_users` (JSON map). Owns one or more namespaces and one or more public subdomains. Also drives a **Workstation profile** (an identity has both a cluster facet and a workstation facet). -_Avoid_: bare "user", "tenant". - -### Workstation (multi-user devvm) - -**devvm**: -The dev VM (`10.0.10.10`), a non-cluster VM on the **PVE host** that hosts each person's Claude Code coding environment (the `t3-serve@<user>` and terminal-lobby sessions). Not a **Node** (it isn't in the cluster). -_Avoid_: calling it a "Node"; "host" (reserved for the PVE host). - -**Workstation**: -A person's identity-scoped Claude Code environment on the **devvm** β€” one OS account, their session runs as that uid. The same human may also be a **Namespace-owner**; the cluster identity and the Workstation are two facets of one person. -_Avoid_: "t3 instance" (only one surface of a Workstation); bare "user". - -**RBAC tier**: -The role band that governs a person everywhere β€” `kubernetes-admins` (Viktor; cluster-admin, secrets, apply), `kubernetes-power-users` (infra-aware, broad read, no destructive change), `kubernetes-namespace-owners` (own-namespace app dev). The single axis that keys both cluster RBAC **and** the **Workstation profile**. -_Avoid_: inventing per-service roles; conflating with **Namespace tier** / **State tier** (those are not identity). - -**Workstation profile**: -The **RBAC tier**-keyed bundle a **Workstation** receives: **Config inheritance** (identical for everyone) plus the person's **Infra visibility** and cluster scope (varies by tier). Never hand-tuned per person β€” one identity decision (Authentik group + `k8s_users`) provisions the cluster facet and the Workstation together. -_Avoid_: per-person bespoke setup (the rejected "stitched-together" status quo). - -**Config inheritance**: -The universal half of every **Workstation profile** β€” Viktor's *static* Claude config (skills, rules, agents, commands, `CLAUDE.md`, hooks) **live-extends** from a **Config base**, it is NOT copied: each person's `~/.claude` draws these from the shared base, so an edit Viktor makes appears in every Workstation immediately, with no seed/copy/sync step. Users may layer their own items on top (rarely do). **RBAC tier**-independent. Per-user *mutable* state (`~/.claude.json`, `.credentials.json`, `projects/`, sessions) is never shared β€” local only. -_Avoid_: a periodic copy/seed/sync of `~/.claude` (rejected β€” inheritance must be live); sharing `~/.claude.json` / `.credentials.json` (per-user, secret-bearing, corrupts under concurrent writes β€” see emo's multi-session profile). - -**Config base**: -The shared, secret-free, version-controlled source of truth for the *static* Claude config that every **Workstation** live-extends (see **Config inheritance**). Viktor's authoring surface β€” when he edits a skill/rule, he edits the base; the chezmoi dotfiles repo is its versioned form (commit = audit/rollback, NOT a push to users). Holds only skills/rules/agents/commands/`CLAUDE.md`/hooks β€” never secrets or per-user mutable state. -_Avoid_: treating it as a per-user seed target (it is a live shared source, not a copy); putting secrets in it. - -**Infra visibility**: -What a non-admin **Workstation** may SEE of the infra: the public repo **code** and the person's own **RBAC**-scoped view of the live cluster (kubectl / dashboard within their namespaces). Explicitly excludes the **git-crypt** secrets (`terraform.tfvars`, `secrets/`) and any out-of-scope mutation. The boundary that "respect their permissions" enforces β€” violated today because `~/code` is one git-crypt-*unlocked* tree shared via the `code-shared` group. -_Avoid_: reading "see the infra" as access to secrets or apply rights. - -### Networking - -**Public domain**: -`viktorbarzin.me`, served through Cloudflare. DNS records are either **proxied** (Cloudflare CDN/WAF in front) or **non-proxied** (direct A/AAAA reachable via Cloudflared Tunnel). -_Avoid_: "external", "outside". - -**Internal domain**: -`viktorbarzin.lan`, served by Technitium DNS. Resolves only inside the homelab network. -_Avoid_: bare "lan", "private", "intranet". - -**Ingress auth**: -The `auth = "..."` parameter on `ingress_factory` β€” a discrete *mode*, not a ranked tier β€” one of `required` (Authentik forward-auth gates every request), `app` (the backend owns its login), `public` (anonymous Authentik binding for audit only), or `none` (Anubis-fronted content, or native-client API). Default `required` (fail-closed). -_Avoid_: "auth tier" / "auth mode" β€” refer to it by the canonical key, `auth` (e.g. `auth = "required"`). "tier" is reserved for State tier and Namespace tier. - -**Authentik outpost**: -A standalone Authentik deployment that terminates the proxy/auth flow for a specific binding model. The repo runs two distinct ones: the default outpost (used by `auth = "required"`) and the `public` outpost (anonymous binding, used by `auth = "public"`). -_Avoid_: conflating outpost with Authentik core; "Authentik instance". - -**Cloudflared Tunnel**: -The channel by which non-proxied **public domain** traffic reaches the cluster, terminating at Traefik. Backs every `dns_type = "non-proxied"` record and is the fallback path for the wildcard `*.viktorbarzin.me`. -_Avoid_: "the tunnel" without "Cloudflared" (could mean Headscale). - -**Ingress chain**: -The opinionated stack of Traefik middlewares that `ingress_factory` layers onto every Ingress. Slots, in order: forward-auth (per **Ingress auth**) β†’ anti-AI scraping (default-on when no Authentik is in the path) β†’ CrowdSec bouncer (fail-open) β†’ retry (2Γ— / 100ms) β†’ rate-limit (429, not 503). Adding or removing a middleware is a Stack-level choice, but the chain order is convention. -_Avoid_: "middleware list", "Traefik chain". The Anubis PoW gate is upstream of this chain, not inside it. - -**MetalLB / LB IP**: -The bare-metal load-balancer that assigns external IPs to `type=LoadBalancer` Services. Two IPs matter: the **shared LB IP** `10.0.20.200` (~10 services β€” PG state-backend, headscale, wireguard, coturn, xray… β€” all `externalTrafficPolicy: Cluster`) and **Traefik's dedicated LB IP** `10.0.20.203` (`externalTrafficPolicy: Local`). Traefik runs on its own IP because ETP:Local preserves the **real client IP** (for CrowdSec) and enables QUIC, and MetalLB forbids mixed ETP on one shared IP. -_Avoid_: calling `.200` "the cluster IP" or assuming all ingress shares one LB IP. - -**Calico**: -The cluster CNI and **NetworkPolicy** engine (also GlobalNetworkPolicy + flow logs). Egress lockdown follows an **observe-then-enforce** rollout β€” flow logs build an empirical allowlist, then default-deny egress is enforced per-namespace, tier by tier (wave 1 began at `recruiter-responder`; Tier 0/1/2 deferred). -_Avoid_: "firewall" (it's pod-level policy, not a perimeter); conflating a Calico **NetworkPolicy** (enforced in the data path) with a **Kyverno policy** (enforced at admission) β€” different layers. - -### Storage - -**proxmox-lvm-encrypted**: -Default StorageClass for any workload holding sensitive data (databases, auth, password managers, email, financial data). LUKS2 over a Proxmox LVM-thin LV. -_Avoid_: bare "encrypted PVC" β€” name the StorageClass. - -**proxmox-lvm**: -Block StorageClass for non-sensitive workloads (caches, monitoring data, indexes, app state without secrets). - -**NFS volume**: -RWX file storage for shared media libraries, large datasets, or anything that needs to be inspected from outside K8s. Provisioned via the `nfs_volume` Module. -_Avoid_: "shared storage" (ambiguous). - -**nfs-truenas StorageClass**: -A historical SC name retained only because StorageClass strings are immutable on bound PVs. The underlying server is the **PVE host**, not TrueNAS; TrueNAS is decommissioned. -_Avoid_: assuming this means TrueNAS. - -**local-path**: -The cluster's Kubernetes default StorageClass (`rancher.io/local-path`) β€” node-local hostpath, **non-replicated**, no CSI snapshots, outside the backup pipeline. A PVC that omits `storageClassName` silently binds here, pinned to one Node's disk. Always set an explicit `storageClassName`; reach for local-path only for genuinely throwaway, node-pinned data. -_Avoid_: relying on the default. Note the two senses of "default": local-path is the *cluster default SC* (what an unspecified PVC gets); proxmox-lvm-encrypted is the *default choice* for sensitive data. Different things. - -**3-2-1 backup**: -The named posture of where data lives: **Copy 1** = live on the PVE thin pool (sdc), **Copy 2** = sda backup disk (`/mnt/backup`), **Copy 3** = offsite Synology NAS. Per-PVC file-level rsync from LVM thin snapshots; databases additionally dump to NFS for per-DB restore. -_Avoid_: bare "backup" without saying which copy you mean (a service is "backed up" only once it's on Copy 2; Copy 3 is the disaster floor). - -### Data - -**CNPG** / **pg-cluster**: -**CNPG** is the CloudNativePG operator; **`pg-cluster`** is the Postgres cluster it manages β€” the shared Postgres substrate. Backs Tier-1 Terraform state (`pg-cluster-rw.dbaas.svc.cluster.local:5432/terraform_state`) and ~12 application databases, reached through **PgBouncer** (a **critical-path Service**) for connection pooling; app credentials rotate via the `vault-database` ClusterSecretStore. -_Avoid_: "the database" (many DBs share one cluster); the legacy `postgresql.dbaas` Service (no endpoints β€” dead); conflating the CNPG operator with the `pg-cluster` it manages. - -### Secrets - -**Vault path**: -Convention: `secret/<service>` for Service-owned secrets, `secret/viktor` for personal/global, `secret/platform` for cluster-wide maps (`k8s_users`, `homepage_credentials`). -_Avoid_: conflating Vault path (e.g. `secret/viktor`) with Vault field (e.g. `forgejo_pull_token`). - -**ExternalSecret** / **ESO**: -A K8s manifest that materialises a Vault KV value as a K8s Secret. Two ClusterSecretStores: `vault-kv` (KV engine) and `vault-database` (rotating DB creds). - -**Plan-time secret**: -A secret value read in Terraform via `data "kubernetes_secret"` (i.e. via the ESO-created K8s Secret) at plan time, with no Vault provider call. Distinct from a **vault data source** read (`data "vault_kv_secret_v2"`), which still goes through the Vault provider. A few Stacks remain hybrid (plan-time for env vars, vault data source for module inputs). - -**Sealed Secret**: -A user-managed secret committed to a Stack directory as `sealed-*.yaml`. Distinct from ExternalSecret β€” Sealed Secrets carry their own bytes, ExternalSecrets reference Vault. - -### CI/CD - -**GHA build + Woodpecker deploy**: -The split where Docker images are built+pushed by GitHub Actions and Woodpecker only runs `kubectl set image` on a deploy-only pipeline. Repos that can't fit GHA limits stay on Woodpecker for build too. -_Avoid_: bare "Woodpecker pipeline" β€” say "build" or "deploy". - -**Keel**: -The **poll-driven** rollout orchestrator β€” watches registries for new image tags and rolls the matching Deployments automatically. The actor behind "auto-upgrade" for upstream images, and a redundant net for owned apps (already rolled on push by **Woodpecker deploy**). -_Avoid_: conflating with **Woodpecker deploy** (push-driven, fires on commit) or **Diun** (watches but only notifies). Never point Keel / `set image` at operator-managed StatefulSets. - -**Diun**: -**Notify-only** image-update monitoring β€” reports that a newer image exists, never rolls anything (contrast **Keel**, which acts). Disabled on pinned images (MySQL, PostgreSQL, Redis) so version pins aren't nagged. -_Avoid_: expecting Diun to deploy; conflating with **Keel**. - -**Anubis**: -A PoW reverse-proxy issuing a 30-day JWT cookie, used in front of public content-bearing sites without app-level auth (blog, wiki, landing pages). Never in front of Git, WebDAV, CalDAV, or API endpoints (clients can't solve PoW). - -## Relationships - -- A **Service** is defined by exactly one **Stack** β€” **flat** or wrapping a **Stack-local module** β€” which sources zero or more shared **Factory modules** and resolves to one or more K8s workloads. -- A **Namespace-owner** owns one or more namespaces and one or more public subdomains. -- A **Service** owns its **Vault path** at `secret/<service>`, surfaces values through **ExternalSecrets**, and reads them at plan time via **plan-time secrets**. -- An **Ingress** picks exactly one **Ingress auth** mode; the choice defines how strangers reach the backend. -- A **proxmox-lvm-encrypted** PVC binds to one Node at a time (RWO) and requires a Service-level backup CronJob; an **NFS volume** is RWX and is backed up at the host level via rsync. -- **State tier** and **Namespace tier** are orthogonal β€” a Tier 0 Stack can deploy a Service into any Namespace tier and vice versa. -- A **Service**'s image reaches the cluster via **Woodpecker deploy** (push-driven, on commit) or **Keel** (poll-driven, on a new registry tag); **Diun** only notifies. Operator-managed StatefulSets are rolled by neither. -- Tier-1 **State tier** state and ~12 app databases share one **CNPG** `pg-cluster`, reached through **PgBouncer**; their credentials rotate via the `vault-database` store. - -## Example dialogue - -> **Dev:** "I'm adding a new **Service** β€” FastAPI backend with its own JWT login. Do I need Authentik?" -> **Domain expert:** "If the FastAPI login is the gate, set `auth = "app"` on the ingress. That records the intent that you _chose_ not to layer Authentik β€” leave a one-line comment above stating what gates the Service, or `scripts/tg` will refuse the apply." -> **Dev:** "And storage?" -> **Domain expert:** "Does it hold user data? If yes, `proxmox-lvm-encrypted` β€” that's the default for anything sensitive. Add a backup CronJob writing to `/mnt/main/<service>-backup/`. If the data is just caches, plain `proxmox-lvm` is fine." -> **Dev:** "What about a Secret with the JWT signing key?" -> **Domain expert:** "Put the key in `secret/<service>` in Vault, then declare an **ExternalSecret** to materialise it as a K8s Secret. Read it at plan time with `data "kubernetes_secret"` β€” that keeps Vault out of the plan path." - -## Flagged ambiguities - -- **"tier"** has exactly two senses β€” always qualify which: *State tier* (Tier 0 / Tier 1, Terraform backend partition) and *Namespace tier* (`0-core`..`4-aux`, scheduling priority/quota). They are orthogonal axes. Do **not** coin new "tier"s: **Ingress auth** is a *mode* (not a tier), and storage speed (SSD vs HDD) is *not* a "tier" either. -- **"node"** can mean a K8s Node (default) or a PVE node. For Proxmox-level statements, say **PVE node** explicitly. -- **"service"** spans two distinct concepts: the deployed app (capitalised **Service**, this repo's domain noun) and the K8s `Service` object (in backticks or qualified "K8s Service"). Lowercase "service" in prose is fine when context disambiguates; flag it when it doesn't. -- **"secret"** spans Vault entries, K8s Secret objects, **ExternalSecrets**, and **Sealed Secrets**. Always specify which. -- **"proxied"** / **"non-proxied"** refer to Cloudflare's CDN posture for a DNS record, _not_ Anubis or forward-auth layering. -- **"policy"** spans **Kyverno policy** (admission-time mutate/generate/validate), **Calico NetworkPolicy** (data-path ingress/egress), Vault policy (KV access), and K8s RBAC. Always qualify which engine. diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md deleted file mode 100644 index e764801a..00000000 --- a/CONTRIBUTING.md +++ /dev/null @@ -1,125 +0,0 @@ -# Contributing to the Infrastructure Repo - -This guide covers the namespace-owner workflow for deploying apps on the cluster.

Apply Stacks - -```bash -vault login -method=oidc - -cd stacks/vault && terragrunt apply --non-interactive -# Creates: namespace, Vault policy, identity entity, K8s deployer role - -cd ../platform && terragrunt apply --non-interactive -# Creates: RBAC bindings, ResourceQuota, TLS secret, DNS records - -cd ../woodpecker && terragrunt apply --non-interactive -# Adds user to Woodpecker admin list -``` - -### What Gets Auto-Generated - -| Resource | Stack | -|----------|-------| -| Kubernetes namespace | vault | -| Vault policy (`namespace-owner-{user}`) | vault | -| Vault identity entity + OIDC alias | vault | -| K8s deployer Role + Vault K8s role | vault | -| RBAC RoleBinding (namespace admin) | platform | -| RBAC ClusterRoleBinding (cluster read-only) | platform | -| ResourceQuota | platform | -| TLS secret in namespace | platform | -| Cloudflare DNS records | platform | -| Woodpecker admin access | woodpecker | - -## New User Onboarding - -If you've been added as a namespace-owner, follow these steps to get started. - -### 1. Join the VPN - -```bash -# Install Tailscale: https://tailscale.com/download -tailscale login --login-server https://headscale.viktorbarzin.me -# Send the registration URL to Viktor, wait for approval -ping 10.0.20.100 # verify connectivity -``` - -### 2. Install Tools - -Run the setup script to install kubectl, kubelogin, Vault CLI, Terraform, and Terragrunt: - -```bash -# macOS -bash <(curl -fsSL https://k8s-portal.viktorbarzin.me/setup/script?os=mac) - -# Linux -bash <(curl -fsSL https://k8s-portal.viktorbarzin.me/setup/script?os=linux) -``` - -### 3. Authenticate - -```bash -# Log into Vault (opens browser for SSO) -vault login -method=oidc - -# Test kubectl (opens browser for OIDC login) -kubectl get pods -n YOUR_NAMESPACE -``` - -### 4. Deploy Your First App - -```bash -# Clone the infra repo -git clone https://github.com/ViktorBarzin/infra.git && cd infra - -# Copy the stack template -cp -r stacks/_template stacks/myapp -mv stacks/myapp/main.tf.example stacks/myapp/main.tf - -# Edit main.tf β€” replace all <placeholders> - -# Store secrets in Vault -vault kv put secret/YOUR_USERNAME/myapp DB_PASSWORD=secret123 - -# Submit a PR -git checkout -b feat/myapp -git add stacks/myapp/ -git commit -m "add myapp stack" -git push -u origin feat/myapp -``` - -After review and merge, an admin runs `cd stacks/myapp && terragrunt apply`. - -### 5. Set Up CI/CD (Optional) - -Create `.woodpecker.yml` in your app's Forgejo repo: - -```yaml -steps: - - name: build - image: woodpeckerci/plugin-docker-buildx - settings: - repo: YOUR_DOCKERHUB_USER/myapp - tag: ["${CI_PIPELINE_NUMBER}", "latest"] - username: - from_secret: dockerhub-username - password: - from_secret: dockerhub-token - platforms: linux/amd64 - - - name: deploy - image: hashicorp/vault:1.18.1 - commands: - - export VAULT_ADDR=http://vault-active.vault.svc.cluster.local:8200 - - export VAULT_TOKEN=$(vault write -field=token auth/kubernetes/login - role=ci jwt=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)) - - KUBE_TOKEN=$(vault write -field=service_account_token - kubernetes/creds/YOUR_NAMESPACE-deployer - kubernetes_namespace=YOUR_NAMESPACE) - - kubectl --server=https://kubernetes.default.svc - --token=$KUBE_TOKEN - --certificate-authority=/var/run/secrets/kubernetes.io/serviceaccount/ca.crt - -n YOUR_NAMESPACE set image deployment/myapp - myapp=YOUR_DOCKERHUB_USER/myapp:${CI_PIPELINE_NUMBER} -``` - -### Useful Commands - -```bash -# Check your pods -kubectl get pods -n YOUR_NAMESPACE - -# View quota usage -kubectl describe resourcequota -n YOUR_NAMESPACE - -# Store/read secrets -vault kv put secret/YOUR_USERNAME/myapp KEY=value -vault kv get secret/YOUR_USERNAME/myapp - -# Get a short-lived K8s deploy token -vault write kubernetes/creds/YOUR_NAMESPACE-deployer \ - kubernetes_namespace=YOUR_NAMESPACE -``` - -### Important Rules - -- **All changes go through Terraform** β€” never `kubectl apply/edit/patch` directly -- **Never put secrets in code** β€” use Vault: `vault kv put secret/YOUR_USERNAME/...` -- **Always use a PR** β€” never push directly to master -- **Docker images**: build for `linux/amd64`, use versioned tags (not `:latest`) - -## git-crypt setup - -To decrypt the secrets, you need to setup [git-crypt](https://github.com/AGWA/git-crypt). - -1.

- -- **Lighter weight**: Lower resource footprint (3+3+3 replicas vs Keycloak's heavier Java runtime) -- **Better UX**: Modern UI, simpler admin experience, better mobile support -- **Python-based**: Easier to extend, faster startup times, better developer experience -- **Active development**: More frequent releases, responsive community - -### Why Forward Auth over Sidecar? - -- **Simpler architecture**: Single auth check at ingress, no sidecar per pod -- **Works with any backend**: Language/framework agnostic, no SDK required -- **Centralized policy**: All auth logic in Authentik, not distributed across sidecars -- **Performance**: Single auth check per session, not per request - -### Why OIDC for Kubernetes? - -- **SSO integration**: Same login as all other services, no separate credentials -- **No credential management**: No kubeconfig secrets to rotate, tokens are short-lived -- **Group-based RBAC**: Centralized group management in Authentik, automatic K8s role mapping -- **Public client flow**: No client secret needed, works in kubectl plugins and dashboards - -### Why Invitation-Only Enrollment? - -- **Security**: Prevents open internet access to homelab services -- **Controlled onboarding**: Explicit approval before granting access -- **Social login convenience**: No password management, leverages trusted providers -- **Group auto-assignment**: Invitation encodes initial group membership - -## Troubleshooting - -### Headers Not Stripped - -**Problem**: Backend receives `X-Authentik-Username`, `X-Authentik-Email`, `X-Authentik-Groups` headers and breaks. - -**Fix**: Traefik middleware should strip these headers before forwarding. Check `ingress_factory` module for header stripping config. - -### OIDC Token Expired - -**Problem**: `kubectl` returns 401 Unauthorized. - -**Fix**: Re-authenticate to refresh token: -```bash -kubectl oidc-login setup --oidc-issuer-url=https://authentik.viktorbarzin.me/application/o/kubernetes/ -``` - -### Social Login Redirect Loop - -**Problem**: After social login, redirects to Authentik login page instead of destination. - -**Fix**: Check Authentik application's redirect URIs. Must include `https://authentik.viktorbarzin.me/source/oauth/callback/*` for social providers. - -### User Not in Correct Group - -**Problem**: User authenticated but lacks permissions. - -**Fix**: Check group membership in Authentik admin UI. Verify invitation `fixed_data` specified correct group. Manually add to group if needed. - -### Vault OIDC Login Fails - -**Problem**: Vault UI redirects to Authentik but returns error. - -**Fix**: -1. Verify Vault OIDC client credentials in Authentik -2. Check Vault OIDC issuer URL matches Authentik -3. Ensure Vault redirect URI (`https://vault.viktorbarzin.me/ui/vault/auth/oidc/oidc/callback`) is registered in Authentik - -### K8s Auth Group Mapping Not Working - -**Problem**: User authenticated but `kubectl` shows limited permissions despite being in `kubernetes-admins`. - -**Fix**: -1. Verify group claim is present in token: `kubectl oidc-login get-token | jq -R 'split(".") | .[1] | @base64d | fromjson'` -2.

A failed `kubeadm upgrade apply` is an outage. Mitigations: - -- **Mandatory etcd snapshot before every run** (even patch). Recovery point if master breaks. -- **Halt-on-alert before every drain**. Reuses the same Prometheus ignore-list regex kured uses β€” any unrelated cluster-health alert blocks. Three gate alerts catch upgrade-specific half-states (version skew, missing snapshot, stalled chain). -- **Job pinning eliminates self-preemption**. Each Job's pod runs on a node that is NOT its drain target. k8s-node1 hosts every Job except the one that drains it (which runs on k8s-master with a control-plane toleration). -- **Sequential workers with 10-min inter-node soak**. Same risk-bounding as the 24h OS-reboot soak, but tightened because kubelet failures surface within minutes β€” not hours. -- **Master upgrade goes first, workers last**. If master breaks, the cluster is already degraded so further worker upgrades would just delay recovery. By upgrading master first, we either succeed (workers can roll afterward) or fail loud (operator triages before any worker is touched). -- **No auto-rollback**. kubeadm doesn't support clean downgrade; the snapshot + manual apt rollback in the runbook is the recovery path. -- **PDB-blocked pods don't stall the chain**. `predrain_unstick` deletes PDB=0 pods on the target node directly (bypassing the eviction API), so the parent Deployment recreates them elsewhere. This was the workaround applied manually during the 2026-05-11 recovery for Anubis single-replica instances. - -### Secrets - -| Secret | Vault Path | Purpose | -|--------|-----------|---------| -| SSH private key | `secret/k8s-upgrade.ssh_key` | Jobs SSH `wizard@<node>` | -| SSH public key | `secret/k8s-upgrade.ssh_key_pub` | Deployed to nodes' `~/.ssh/authorized_keys` | -| Slack webhook | `secret/k8s-upgrade.slack_webhook` | Pipeline notifications (separate channel from kured) | - -The previous `api_bearer_token` entry is gone β€” the chain does not POST to `claude-agent-service`. - -### Operational reference - -See `docs/runbooks/k8s-version-upgrade.md` for: verifying health, manually triggering detection, killing a stuck Job, skipping a phase, rollback paths (master / worker / mid-flight abort), and SSH key rotation. diff --git a/docs/architecture/backup-dr.md b/docs/architecture/backup-dr.md deleted file mode 100644 index 60c1c77d..00000000 --- a/docs/architecture/backup-dr.md +++ /dev/null @@ -1,961 +0,0 @@ -# Backup & Disaster Recovery Architecture - -Last updated: 2026-06-01 - -> **2026-06-01 β€” regenerable services carved back out** (offsite Synology hit -> 97%; the `Backup` share had grown +670 G in a week, traced to the 2026-05-26 -> change below that started mirroring large regenerable data offsite): -> - **`nfs-mirror` re-excludes** `ollama` (20 G), `prometheus-backup` (64 G), -> `audiblez` (24 G), `ebook2audiobook` (11 G).

These are CoW snapshots β€” instant creation, minimal overhead, sharing the thin pool's free space. - -**Script**: `/usr/local/bin/lvm-pvc-snapshot` on PVE host (source: `infra/scripts/lvm-pvc-snapshot.sh`). Deploy: `scp infra/scripts/lvm-pvc-snapshot.sh root@192.168.1.127:/usr/local/bin/lvm-pvc-snapshot` -**Schedule**: Daily 03:00 via systemd timer, 7-day retention -**Discovery**: Auto-discovers PVC LVs matching `vm-*-pvc-*` pattern in VG `pve` thin pool `data` - -**Coverage**: All 65 proxmox-lvm PVCs **except** `dbaas` and `monitoring` namespaces. These are excluded because: -- MySQL InnoDB, PostgreSQL, and Prometheus are high-churn (50%+ CoW divergence/hour) -- They already have app-level dumps (Layer 2) -- Including them causes ~36% write amplification; excluding them reduces overhead to ~0% - -**Monitoring**: Pushes metrics to Pushgateway via NodePort (30091). Alerts: `LVMSnapshotStale` (>30h since last run + 30m `for:`), `LVMSnapshotFailing`, `LVMThinPoolLow` (<15% free). - -**Restore**: `lvm-pvc-snapshot restore <pvc-lv> <snapshot-lv>` β€” auto-discovers K8s workload, scales down, swaps LVs, scales back up. See `docs/runbooks/restore-lvm-snapshot.md`. - -### Layer 2: Weekly File-Level Backup (sda Backup Disk) - -**Backup disk**: sda (1.1TB RAID1 SAS) β†’ VG `backup` β†’ LV `data` β†’ ext4 β†’ mounted at `/mnt/backup` on PVE host. Dedicated backup disk, independent of live storage. - -**Script**: `/usr/local/bin/daily-backup` on PVE host (source: `infra/scripts/daily-backup.sh`) -**Schedule**: Daily 05:00 via systemd timer -**Retention**: 4 weekly versions (weeks 0-3 via `--link-dest` hardlink dedup) - -#### What Gets Backed Up - -**1. PVC File Copies** (`/mnt/backup/pvc-data/<YYYY-WW>/`): -- Mount each LVM thin LV ro on PVE host β†’ rsync files (not block) β†’ unmount -- 62 PVCs covered (all except dbaas + monitoring) -- Organized as `/mnt/backup/pvc-data/<YYYY-WW>/<namespace>/<pvc-name>/` -- 4 weekly versions with `--link-dest` hardlink dedup (unchanged files share inodes) - -**2. Auto SQLite Backup** (`/mnt/backup/sqlite-backup/`): -- Detects SQLite databases in PVC snapshots via magic number check (`SQLite format 3`) -- Opens each database with `?mode=ro` (read-only, safe β€” no WAL replay) -- Runs `.backup` to create a consistent copy -- Covers all SQLite files across all PVC snapshots automatically - -**3. pfSense Backup** (`/mnt/backup/pfsense/<YYYY-WW>/`): -- `config.xml` via API (base64 decode) -- Full filesystem tar via SSH (`tar czf /tmp/pfsense-full.tar.gz /cf /var/db /boot/loader.conf`) -- 4 weekly versions - -**4. PVE Config** (`/mnt/backup/pve-config/`): -- `/etc/pve/` (cluster config, VM definitions) -- `/usr/local/bin/` (custom scripts) -- `/etc/systemd/system/` (timers) -- Single copy (no rotation) - -**Auto-discovered BACKUP_DIRS**: Uses glob-based discovery instead of a hardcoded list. Any new PVC LV matching `vm-*-pvc-*` is automatically included. - -**Snapshot Pruning**: Deletes LVM snapshots older than 7 days (safety net for snapshots that outlive `lvm-pvc-snapshot` timer). - -**Monitoring**: Pushes `daily_backup_last_run_timestamp`, `daily_backup_last_status`, and `daily_backup_bytes_synced` to Pushgateway (job `daily-backup`). Alerts: `WeeklyBackupStale` (>9d on `daily_backup_last_run_timestamp`), `WeeklyBackupFailing` (`daily_backup_last_status != 0`). The metric is pushed both on clean exit AND from a `trap TERM INT` handler β€” a 2026-04-30 β†’ 2026-05-09 silent-failure incident traced to systemd SIGTERMing the script before it reached its final push, leaving the alert blind. - -### Layer 2b: Application-Level Backups - -K8s CronJobs run inside the cluster, dumping database/state to NFS-exported backup directories. Each service writes to `/srv/nfs/<service>-backup/` (some legacy paths still use `/mnt/main/<service>-backup/`). - -**Why needed**: LVM snapshots capture block-level state, but: -- Cannot restore individual databases from a PostgreSQL snapshot -- Proxmox CSI LVs are opaque raw block devices -- Need point-in-time recovery for specific apps without full LVM rollback - -**Daily backups (00:00-00:30)**: -- **PostgreSQL full** (`pg_dumpall`, 00:00): Dumps all databases to `/mnt/main/postgresql-backup/dump_*.sql.gz`. 14-day rotation. -- **PostgreSQL per-db** (`pg_dump -Fc`, 00:15): Dumps each database individually to `/mnt/main/postgresql-backup/per-db/<dbname>/dump_*.dump`. Enables single-database restore via `pg_restore -d <db> --clean --if-exists`. 14-day rotation. -- **MySQL full** (`mysqldump --all-databases`, 00:30): Dumps all databases to `/mnt/main/mysql-backup/dump_*.sql.gz`. 14-day rotation. -- **MySQL per-db** (`mysqldump`, 00:45): Dumps each database individually to `/mnt/main/mysql-backup/per-db/<dbname>/dump_*.sql.gz`. Enables single-database restore. 14-day rotation. - -**Daily backups (Sunday 01:00-04:00)**: -- **etcd**: `etcdctl snapshot save /mnt/main/etcd-backup/snapshot-$(date +%Y%m%d).db`. 30-day retention. Critical for cluster recovery. -- **Vaultwarden**: See "Vaultwarden Enhanced Protection" below. 30-day retention. -- **Vault**: `vault operator raft snapshot save /mnt/main/vault-backup/snapshot-$(date +%Y%m%d).snap`. 30-day retention. -- **Redis**: `redis-cli BGSAVE` then copy RDB file. 30-day retention. - -### Vaultwarden Enhanced Protection - -Vaultwarden stores sensitive password vault data in SQLite on a proxmox-lvm volume. Extra safeguards prevent corruption: - -**Every 6 hours** (vaultwarden-backup CronJob): -1. Run `PRAGMA integrity_check` on live database -2. If check fails β†’ abort (alert fires) -3. If check passes β†’ `sqlite3 .backup /mnt/main/vaultwarden-backup/db-$(date +%Y%m%d%H%M).sqlite` -4. Run `PRAGMA integrity_check` on backup copy -5. Copy RSA keys, attachments, sends folder, config.json -6. Rotate backups older than 30 days - -**Every hour** (vaultwarden-integrity-check CronJob): -1. Run `PRAGMA integrity_check` on live database -2. Push metric to Pushgateway: `vaultwarden_sqlite_integrity_ok{status="ok"}=1` or `=0` -3. Prometheus scrapes Pushgateway and alerts on `integrity_ok == 0` - -This provides both frequent backups (every 6h) AND continuous integrity monitoring (hourly). - -### Layer 3: Offsite Sync to Synology NAS - -**Script**: `/usr/local/bin/offsite-sync-backup` on PVE host (source: `infra/scripts/offsite-sync-backup`) -**Schedule**: Daily 06:00 via systemd timer (After=daily-backup.service) - -Two-step offsite sync: - -#### Step 1: sda to Synology pve-backup/ - -**Method**: `rsync` from `/mnt/backup/` to `synology.viktorbarzin.lan:/Backup/Viki/pve-backup/` -**Content**: PVC snapshots (`pvc-data/`), pfSense backups, PVE config, SQLite backups, **plus the nfs-mirror output** (anca-elements + ~30 critical NFS subtrees) β€” see Layer 3a. After consolidation, sda is the single source for the bulk of Synology's payload. - -**Destination**: `Synology/Backup/Viki/pve-backup/`: -- `pvc-data/<YYYY-WW>/` β€” 4 weekly PVC file backups -- `sqlite-backup/` β€” auto SQLite backups -- `pfsense/<YYYY-WW>/` β€” 4 weekly pfSense backups -- `pve-config/` β€” latest PVE config -- `anca-elements/`, `mysql/`, `postgresql/`, `nextcloud/`, `health/`, `<other critical NFS dirs>/` β€” from nfs-mirror (Layer 3a) - -#### Step 2: sda-bypass NFS to Synology nfs/ + nfs-ssd/ (inotify change-tracked, FILTERED) - -**Role**: Carries the single path that bypasses sda β€” `/srv/nfs/immich/` (1.5 T, doesn't fit on sda). Plus the full `/srv/nfs-ssd/` (immich-ML + ollama + llamacpp; the SSD has no sda-mirror leg). Everything else under `/srv/nfs/` rides leg 1. - -**Method**: `rsync --files-from /mnt/backup/.nfs-changes.log` with regex filter `^/srv/nfs/immich/`. The monthly full sync uses `--include='/immich/***' --exclude='*'` for the HDD leg, and a plain `--delete` for the SSD leg. - -**Change tracking**: `nfs-change-tracker.service` (systemd, inotifywait) on PVE host watches `/srv/nfs` and `/srv/nfs-ssd` continuously. Changed file paths are logged to `/mnt/backup/.nfs-changes.log`. Step 2 reads this log and transfers only changed files matching the bypass regex. Incremental syncs complete in seconds. - -**Monthly full sync**: On 1st Sunday of month, runs `rsync --delete` with the immich-only include list. The `--delete` pass also reaps any stale Synology `/Viki/nfs/<dir>/` from the broader pre-2026-05-26 bypass list (ollama, audiblez, ebook2audiobook, *-backup, frigate, prometheus, loki, temp, alertmanager). - -**`/srv/nfs/anca-elements/` history**: had its own dedicated Synology exclusion line earlier in 2026-05-24 because the original Synology source (`/volume1/Backup/Anca/Elements`) was being preserved while we moved canonical to PVE. After the original was deleted (same day), anca-elements joined the broader "NOT bypassing sda" category and is covered by Step 1 via `nfs-mirror`. - -**Layer 3a: NFS local mirror on sda (3-2-1 second copy)**: `/usr/local/bin/nfs-mirror` rsyncs `/srv/nfs/` β†’ `/mnt/backup/<service>/` daily at 02:00 (switched from weekly Mon 04:00 on 2026-05-26 β€” steady-state delta is 10-20 min of mostly-metadata rsync, cuts non-CronJob app-data RPO from 7d to ~24h). Single rsync invocation, single destination. As of 2026-05-26 the skip-list (in `nfs-mirror.sh` `EXCLUDES`) is intentionally minimal: - -- **immich** (1.5 T) β€” too big for sda; ships sdc β†’ Synology direct (leg 2) -- **frigate** (camera ring buffer) β€” intentionally NOT backed up -- **temp** (scratch) β€” intentionally NOT backed up -- **anca-elements** (legacy) β€” now in Immich; `/mnt/backup/anca-elements` deleted 2026-05-26 -- **/srv/nfs-ssd** entirely β€” its three dirs (immich-ML, ollama, llamacpp) all ship direct to Synology nfs-ssd/ - -Everything else under `/srv/nfs/` β€” mysql, postgresql, nextcloud, health, real-estate-crawler, audiobookshelf, servarr, technitium, openclaw, ollama (HDD), audiblez, ebook2audiobook, every `*-backup` CronJob output, … β€” lands at `/mnt/backup/<svc>/`. Mirror size β‰ˆ 400 GB post-2026-05-26 (was ~900 GB with anca-elements). - -Pushes `nfs_mirror_last_run_timestamp` + `nfs_mirror_last_status` + `nfs_mirror_bytes` to Pushgateway. Alerts: `NfsMirrorStale` (>16d), `NfsMirrorFailing` (status != 0). `rsync -rlt --delete -H --no-perms --no-owner --no-group`; idempotent.

- -**3 copies**: -- Live PVCs (zero RTO for recent data) -- sda local backup (fast recovery without network) -- Synology offsite (site-level disaster protection) - -**2 media types**: -- sdc SSD (live, low latency) -- sda HDD (backup, cost-effective bulk storage) - -**1 offsite**: -- Protection against fire, theft, catastrophic hardware failure -- Weekly RPO acceptable for offsite (daily/weekly app backups reduce exposure) - -### Why File-Level + Block-Level Snapshots? - -**LVM snapshots** (Layer 1): -- Near-instant (<1s), zero overhead -- Point-in-time recovery for entire PVCs -- BUT: Cannot restore individual files, no offsite protection, 7-day retention - -**File-level backup** (Layer 2): -- Can restore single files or directories -- Offsite-compatible (rsync) -- Longer retention (4 weeks local, unlimited offsite) -- BUT: Slower RTO (rsync), higher storage overhead - -Both together provide flexibility: fast local rollback for recent changes, granular recovery for older data. - -### Why Dedicated Backup Disk (sda)? - -**Isolation**: If sdc fails (thin pool corruption, controller failure), sda is independent (different disk, different VG). - -**Performance**: Backup I/O doesn't compete with live PVC I/O. - -**Simplicity**: Single mount point (`/mnt/backup/`) for all backup data, easy to monitor disk usage. - -### Why Not Velero/Longhorn Backup? - -Evaluated K8s-native backup solutions (Velero, Longhorn): -- **Velero**: Requires object storage backend, complex restore, doesn't handle databases well -- **Longhorn**: High overhead (replicas, snapshots in-cluster), no offsite by default - -**Current approach wins** because: -- Leverages existing Proxmox LVM infrastructure (already running) -- Database-native backups (pg_dump/mysqldump) are battle-tested -- Simple restore procedures (documented runbooks) -- Lower resource overhead (no in-cluster replicas) - -### Why Hybrid Incremental + Full Sync? - -**Incremental alone** (rsync --files-from via inotify change log) is risky: -- Deleted files on source never deleted on destination -- Renamed paths create duplicates -- No cleanup of orphaned files - -**Full sync alone** (rsync --delete) is slow: -- 30-60 min per run (all files scanned) -- 7d RPO β†’ 14d if a sync fails - -**Hybrid approach**: -- Fast incremental weekly via inotify change tracking (completes in seconds) -- Monthly full `rsync --delete` for cleanup (tolerates longer runtime) - -### Why 6h Vaultwarden Backup vs Daily for Others? - -Vaultwarden stores **password vault data** β€” highest-value target: -- User creates 10 new passwords β†’ disaster 5h later β†’ daily backup loses all 10 -- 6h RPO acceptable for password vaults (industry standard is 1-24h) -- Hourly integrity checks detect corruption before it spreads to backups - -Other services (MySQL, PostgreSQL): -- Mostly application data (not authentication secrets) -- Daily RPO acceptable per user tolerance -- Lower change velocity - -## Troubleshooting - -### LVM Snapshot Restore Issues - -See `docs/runbooks/restore-lvm-snapshot.md`. - -### Weekly Backup Failing - -**Symptom**: `WeeklyBackupStale` or `WeeklyBackupFailing` alert - -**Diagnosis**: -```bash -ssh root@192.168.1.127 -systemctl status daily-backup.service -journalctl -u daily-backup.service --since "7 days ago" -df -h /mnt/backup -``` - -**Common causes**: -- Backup disk full (check `df -h /mnt/backup`, alert: `BackupDiskFull`) -- LV mount failed (check `lvs pve`, `dmesg | grep backup`) -- NFS mount failed (check `showmount -e 192.168.1.127`) - -**Fix**: -1.

If the GPU card is physically moved to a different -node, gpu-feature-discovery moves the `nvidia.com/gpu.present=true` -label with it, and `null_resource.gpu_node_config` re-applies the -`nvidia.com/gpu=true:PreferNoSchedule` taint to the new host on the -next apply (discovery keyed on -`feature.node.kubernetes.io/pci-10de.present=true`). - -**GPU Workloads** (time-sliced β€” node advertises `Tesla-T4-SHARED`, -`sharing-strategy=time-slicing`, `nvidia.com/gpu.replicas=100`, so many pods -share the single T4; request `nvidia.com/gpu: 1` for a slice, not the whole card): -- immich-machine-learning (CLIP smart-search + facial recognition, CUDA) -- immich-server (NVENC/NVDEC video transcoding β€” `ffmpeg.accel=nvenc` + `accelDecode=true`) -- Frigate (object-detection inference) -- llama-cpp / llama-swap (LLM inference) -- nvidia-exporter + gpu-pod-exporter (DCGM metrics) - -## Configuration - -### Key Files - -| Path | Purpose | -|------|---------| -| `modules/namespace_config/` | Kyverno policies for LimitRange + ResourceQuota generation | -| `modules/k8s_app/main.tf` | Default resource templates for apps | -| `stacks/<service>/terragrunt.hcl` | Per-service resource overrides | -| `modules/gpu_app/` | GPU-specific resource templates | - -### Terraform Resource Configuration - -**Standard App** (no PVC): -```hcl -module "app" { - source = "../../modules/k8s_app" - - resources = { - requests = { - memory = "1Gi" # VPA upperBound * 1.2 - cpu = "500m" - } - limits = { - memory = "1Gi" # Same as request - # No CPU limit - } - } -} -``` - -**App with Democratic-CSI PVC**: -```hcl -module "app" { - source = "../../modules/k8s_app" - - resources = { - requests = { - memory = "2Gi" - cpu = "500m" - } - limits = { - memory = "2Gi" - } - } - - sidecar_resources = { - requests = { - memory = "32Mi" - cpu = "10m" - } - limits = { - memory = "80Mi" - } - } -} -``` - -**GPU App**: -```hcl -module "gpu_app" { - source = "../../modules/gpu_app" - - gpu_count = 1 - - resources = { - requests = { - memory = "8Gi" # VPA upperBound * 1.3 - cpu = "2" - } - limits = { - memory = "8Gi" - nvidia.com/gpu = 1 - } - } -} -``` - -### Kyverno Policies - -**LimitRange Generation** (`modules/namespace_config/limitrange-policy.yaml`): -```yaml -apiVersion: kyverno.io/v1 -kind: ClusterPolicy -metadata: - name: generate-limitrange -spec: - rules: - - name: generate-limitrange-0-core - match: - resources: - kinds: - - Namespace - name: "0-core-*" - generate: - kind: LimitRange - data: - spec: - limits: - - default: - memory: 512Mi - cpu: 500m - defaultRequest: - memory: 512Mi - cpu: 500m - max: - memory: 8Gi - cpu: 4 - type: Container -``` - -**ResourceQuota Generation** (`modules/namespace_config/resourcequota-policy.yaml`): -```yaml -apiVersion: kyverno.io/v1 -kind: ClusterPolicy -metadata: - name: generate-resourcequota -spec: - rules: - - name: generate-quota-0-core - match: - resources: - kinds: - - Namespace - name: "0-core-*" - generate: - kind: ResourceQuota - data: - spec: - hard: - requests.cpu: "32" - requests.memory: 64Gi - pods: "100" -``` - -## Decisions & Rationale - -### Why no CPU limits? - -**Decision**: Set CPU requests but never set CPU limits. - -**Rationale**: -- **CFS Throttling**: Linux Completely Fair Scheduler throttles containers to their exact CPU limit, even when CPU is idle. This causes artificial performance degradation. -- **Burstability**: Services can burst to unused CPU during low-load periods, improving response times. -- **Memory-bound**: With 272GB physical host RAM (~160GB allocated to K8s VMs), memory is no longer the primary constraint. ~112GB headroom available for new VMs. - -**Tradeoff**: A runaway process could monopolize CPU. Mitigated by CPU requests reserving capacity and PriorityClass preemption. - -**Evidence**: After removing CPU limits cluster-wide, p95 latency dropped 40% for API services during load tests. - -### Why Goldilocks in Initial mode instead of Auto? - -**Decision**: Use VPA in "Initial" (recommend-only) mode rather than "Auto" (update pods automatically). - -**Rationale**: -- **Terraform State Drift**: VPA Auto mode directly mutates Deployment specs, creating drift from Terraform-managed state. Next Terraform apply reverts VPA changes. -- **Declarative Workflow**: Terraform is the source of truth. VPA recommendations are reviewed and applied via Terraform, maintaining declarative infrastructure. -- **Controlled Changes**: Quarterly review ensures resource changes align with capacity planning and cluster upgrades. -- **Avoid Thrashing**: VPA Auto can restart pods frequently during volatile workloads. Manual application reduces churn. - -**Tradeoff**: Requires quarterly manual review. Accepted because homelab prioritizes stability over auto-optimization. - -### Why memory requests = limits for tiers 0-2? - -**Decision**: Set memory requests equal to limits for core and cluster services (tiers 0-2). - -**Rationale**: -- **Guaranteed QoS**: Ensures pods are last to be evicted during memory pressure. -- **Predictable OOM**: Pods are OOMKilled only when exceeding their own limit, not due to other pods' usage. -- **Stability**: Critical services (traefik, authentik, vault) must not be evicted unexpectedly. - -**Tradeoff**: Cannot burst above limit. Accepted because critical services are right-sized via VPA. - -### Why Burstable QoS for tiers 3-4? - -**Decision**: Set memory requests < limits for edge and auxiliary services (tiers 3-4). - -**Rationale**: -- **Reduced Scheduler Pressure**: Lower memory requests allow more pods to fit on nodes. -- **Acceptable Eviction**: Tier 3-4 services are non-critical (freshrss, vaultwarden) and tolerate occasional eviction. -- **Cost Efficiency**: Allows oversubscription of memory for bursty workloads. - -**Tradeoff**: Pods may be evicted during memory pressure. Accepted because tier 3-4 services have PriorityClass 200K-300K. - -### Why VPA upperBound * 1.2 (or 1.3)? - -**Decision**: Set memory limits to VPA upperBound * 1.2 for stable services, * 1.3 for GPU/volatile services. - -**Rationale**: -- **Headroom**: VPA upperBound is the observed maximum usage. Adding 20-30% headroom prevents OOMKills during traffic spikes. -- **Growth Buffer**: Services grow over time (more users, more data). Headroom delays the need for manual intervention. -- **GPU Volatility**: GPU workloads (ML inference) have unpredictable memory usage. 30% headroom reduces OOMKills. - -**Tradeoff**: Slightly higher memory allocation. Accepted because 272GB RAM provides ample capacity. - -## Troubleshooting - -### Pods stuck in Pending state - -**Symptom**: Pod shows `status: Pending` with event `FailedScheduling`. - -**Diagnosis**: -```bash -kubectl describe pod <pod-name> -n <namespace> -``` - -**Common Causes**: - -1. **ResourceQuota exceeded**: - ``` - Error: exceeded quota: <namespace>-quota, requested: requests.memory=2Gi, used: requests.memory=14Gi, limited: requests.memory=16Gi - ``` - **Fix**: Increase ResourceQuota in `modules/namespace_config/` for that tier, or reduce other pods' requests. - -2. **LimitRange default too high**: - ``` - 0/5 nodes are available: 5 Insufficient memory. - ``` - **Fix**: Override pod resources explicitly in Terraform (defaults come from LimitRange). - -3. **GPU taint not tolerated**: - ``` - 0/5 nodes are available: 1 node(s) had untolerated taint {nvidia.com/gpu: true}, 4 Insufficient nvidia.com/gpu. - ``` - **Fix**: Add toleration and nodeSelector for GPU pods. - -4. **No nodes with GPU**: - ``` - 0/5 nodes are available: 5 Insufficient nvidia.com/gpu. - ``` - **Fix**: Verify the GPU-carrying node is Ready and has the `nvidia.com/gpu.present=true` label.

Clients talk to `redis-master.redis.svc.cluster.local:6379`, which now selects the single redis pod directly. **No Sentinel, no HAProxy, no replicas** β€” reverted from 3-node HA on 2026-05-30 (see "Why standalone" below). - -**Architecture**: - -1 pod in StatefulSet `redis-v2` (`replicas=1`, `podManagementPolicy=Parallel` retained for STS-field immutability), running `redis` + `redis_exporter` containers on `docker.io/library/redis:8-alpine` (8.6.2). Data on a `proxmox-lvm-encrypted` PVC (`data-redis-v2-0`, 5Giβ†’20Gi autoresize). - -- `maxmemory=640mb` (83% of the 768Mi pod limit), **`maxmemory-policy=volatile-lru`**. The instance is shared by two workload classes: CACHES (want LRU eviction of disposable keys) and QUEUES (Immich BullMQ `bull:*`, Celery `_kombu:*` β€” must never be evicted or jobs vanish). `volatile-lru` evicts only keys carrying a TTL (caches set them) and never touches TTL-less keys (queue jobs), serving both correctly in one instance. Backstop: alert `RedisMemoryPressure` at 80% β€” if it ever fills with non-volatile keys, writes error like `noeviction`. -- Persistence: RDB (`save 900 1 / 300 100 / 60 10000`) + AOF `appendfsync=everysec`. `aof-load-corrupt-tail-max-size=1024` tolerates ≀1KB of AOF tail garbage from an unclean reboot instead of crashlooping. Disk-wear (sdb Samsung 850 EVO, 150 TBW): Redis contributes <1 GB/day cluster-wide β†’ 40+ year runway. -- Memory `requests=limits=768Mi`. BGSAVE + AOF-rewrite fork can double RSS via COW; `auto-aof-rewrite-percentage=200` + `auto-aof-rewrite-min-size=128mb` tune down rewrite frequency. -- Service `redis-master` (name/DNS unchanged across the HA teardown so no consumer needed editing). Keel opt-out (`keel.sh/policy=never`, label + annotation) β€” a prior patch-bump to `:8.0.6-alpine` rejected the AOF config and crashed it. -- Weekly RDB backup to NFS (`/srv/nfs/redis-backup/`, Sunday 03:00, 28-day retention, Pushgateway metrics). -- Auth disabled β€” NetworkPolicy is the isolation layer. `requirepass` + creds rollout to all clients remains a planned follow-up. -- **Downtime model**: a single instance means a pod restart (image bump, node drain, OOM) is a few-seconds cluster-wide Redis blip. Explicitly accepted (Viktor, 2026-05-30) as the price of eliminating the HA failure modes below. There is no PDB (a single-replica PDB would only block node drains). - -**Observability**: `oliver006/redis_exporter:v1.62.0` sidecar on port 9121, auto-scraped. Alerts: `RedisDown`, `RedisMemoryPressure` (>80%), `RedisEvictions`, `RedisForkLatencyHigh`, `RedisAOFRewriteLong`, `RedisBackupStale`, `RedisBackupNeverSucceeded`. (`RedisReplicationLagHigh` + `RedisReplicasMissing` removed with the replicas.) - -**Why standalone** β€” HA Redis caused more outages than it prevented in this homelab. Five incidents: (a) 2026-04-04 service selector routed writes to a replica β†’ `READONLY`; (b) 2026-04-19 AM master OOMKilled during BGSAVE+PSYNC (256Mi too tight); (c) 2026-04-19 PM sentinel quorum drift (2 sentinels, no majority) routed writes to a slave; (d) 2026-04-22 five-factor flap cascade (soft anti-affinity co-located pods + aggressive sentinel/probe timing + HAProxy polling race); (e) **2026-05-30 split-brain** β€” `redis-v2-0` booted during a network partition, hit the init script's deterministic "pod-0 is bootstrap master" fallback, and became a SECOND master alongside the sentinel-elected `redis-v2-2`; HAProxy's `expect rstring role:master` matched both and round-robined client connections across them, so Immich enqueued BullMQ jobs on one master while its workers blocked-popped on the other β†’ every queue wedged, new-upload thumbnails 404'd cluster-wide. The 3-sentinel design (beads `code-v2b`) was built specifically to prevent split-brain after incident (c), yet the bootstrap fallback manufactured one anyway. Conclusion: for a homelab cache/broker, a single instance with a few-seconds restart blip is strictly simpler and more reliable than chasing Sentinel correctness. Mirrors the MySQL InnoDB-Cluster β†’ standalone reversion (2026-04-16).

LAN clients resolving non-proxied `*.viktorbarzin.me` domains get the public IP `176.12.22.76`, but can't reach it because the TP-Link won't route back to the local network. - -### Solution - -Technitium's **Split Horizon AddressTranslation** app post-processes DNS responses for 192.168.1.0/24 clients, translating the public IP to the internal Traefik LB IP: - -``` -176.12.22.76 β†’ 10.0.20.200 -``` - -**DNS Rebinding Protection** has `viktorbarzin.me` in `privateDomains` to allow the translated private IP without being stripped as a rebinding attack. - -### Scope - -- **Affected**: Non-proxied domains (ha-sofia, immich, headscale, calibre, vaultwarden, etc.) for 192.168.1.x clients -- **Not affected**: Cloudflare-proxied domains (resolve to Cloudflare edge IPs, no translation needed) -- **Not affected**: 10.0.x.x and K8s clients (reach public IP via pfSense outbound NAT normally) - -Config is synced to all 3 Technitium instances by CronJob `technitium-split-horizon-sync` (every 6h). - -## NodeLocal DNSCache - -A DaemonSet in `kube-system` (`node-local-dns`, image `registry.k8s.io/dns/k8s-dns-node-cache:1.23.1`) runs on every node including the control plane. Each pod uses `hostNetwork: true` + `NET_ADMIN` and installs iptables NOTRACK rules so it transparently serves DNS on both: - -- **169.254.20.10** β€” the canonical link-local IP from the upstream docs -- **10.96.0.10** β€” the `kube-dns` ClusterIP, so existing pods (which already use this as their nameserver) hit the on-node cache with no kubelet change - -Cache misses go to a separate `kube-dns-upstream` ClusterIP service (not `kube-dns`, to avoid looping back to ourselves) that selects the CoreDNS pods directly via `k8s-app=kube-dns`. - -Priority class is `system-node-critical`; tolerations are permissive (`operator: Exists`) so the DaemonSet runs on tainted master and other reserved nodes. Kyverno `dns_config` drift is suppressed via `ignore_changes` on the DaemonSet. - -**Caching**: `cluster.local:53` caches 9984 success / 9984 denial entries with 30s/5s TTLs. Other zones cache 30s. If CoreDNS is killed, nodes keep answering cached names β€” verified on 2026-04-19 by deleting all three CoreDNS pods and running `dig @169.254.20.10 idrac.viktorbarzin.lan` + `dig @169.254.20.10 github.com` from a pod (both returned answers). - -**Kubelet clusterDNS**: **Unchanged** β€” still `10.96.0.10`. NodeLocal DNSCache co-listens on that IP so traffic interception is transparent; switching kubelet to `169.254.20.10` would require a rolling reconfigure of every node and provides no additional cache benefit over transparent mode. - -**Metrics**: A headless Service `node-local-dns` (ClusterIP `None`) exposes each pod on port `9253` for Prometheus scraping (annotated `prometheus.io/scrape=true`). - -## CoreDNS Configuration - -CoreDNS is managed via Terraform in `stacks/technitium/modules/technitium/` β€” the Corefile ConfigMap lives in `main.tf`, and scaling/PDB are in `coredns.tf` (a `kubernetes_deployment_v1_patch` against the kubeadm-managed Deployment). - -``` -.:53 { - errors / health / ready - kubernetes cluster.local in-addr.arpa ip6.arpa # K8s service discovery - prometheus :9153 # Metrics - forward . 10.0.20.1 8.8.8.8 1.1.1.1 { - policy sequential # try upstreams in order - health_check 5s # mark unhealthy in 5s - max_fails 2 - } - cache { - success 10000 300 6 - denial 10000 300 60 - serve_stale 86400s # resilience during upstream outage - } - loop / reload / loadbalance -} - -viktorbarzin.lan:53 { - template: .*\..*\.viktorbarzin\.lan\.$ β†’ NXDOMAIN # ndots:5 junk filter - forward . 10.96.0.53 { # Technitium ClusterIP - health_check 5s - max_fails 2 - } - cache (success 10000 300, denial 10000 300, serve_stale 86400s) -} -``` - -**Scaling**: 3 replicas, `required` anti-affinity on `kubernetes.io/hostname` (spread across 3 distinct nodes). PodDisruptionBudget `coredns` with `minAvailable=2`. - -**Kyverno ndots injection**: A Kyverno policy injects `ndots:2` on all pods cluster-wide to reduce search domain expansion noise. The template regex is a second layer of defense for any queries that still get expanded. - -**Failover behaviour**: With `policy sequential` on the root forward block, CoreDNS tries pfSense first; if `health_check 5s` detects pfSense as down, it fails over to 8.8.8.8 then 1.1.1.1 within ~5s rather than timing out per-query. Combined with `serve_stale`, pods keep resolving cached names for up to 24h even with full upstream failure. - -## Cloudflare DNS β€” External Domains - -All public domains are under the `viktorbarzin.me` zone. DNS records are **auto-created per service** via the `ingress_factory` module's `dns_type` parameter. A small number of records (Helm-managed ingresses, special cases) remain centrally managed in `config.tfvars`. - -### How DNS Records Are Created - -``` -stacks/<service>/main.tf - module "ingress" { - source = ingress_factory - dns_type = "proxied" # ← auto-creates Cloudflare DNS record - } -``` - -- **`dns_type = "proxied"`**: Creates CNAME β†’ `{tunnel_id}.cfargotunnel.com` (Cloudflare CDN) -- **`dns_type = "non-proxied"`**: Creates A β†’ public IP + AAAA β†’ IPv6 -- **`dns_type = "none"`** (default): No DNS record - -The Cloudflare tunnel uses a **wildcard rule** (`*.viktorbarzin.me β†’ Traefik`) β€” no per-hostname tunnel config needed.

See [Storage & Backup Architecture](storage.md) for the 3-2-1 flow. - -## Decisions & Rationale - -### No Backup MX -- **Alternatives considered**: ForwardEmail (free relay), Cloudflare Email Routing, Dynu Store/Forward -- **Decision**: Direct MX only. ForwardEmail relay was evaluated (2026-04-12) and abandoned β€” its anti-spoofing enforcement rejects legitimate forwarded mail regardless of SPF configuration. Cloudflare Email Routing can't store-and-forward (pass-through proxy only). Dynu ($9.99/yr) is a viable future option. -- **Tradeoff**: If server is down, mail delivery relies on sender MTA retry queues (4-5 days standard). No immediate forwarding to a backup address. - -### Brevo for Outbound (migrated from Mailgun 2026-04-12) -- **Decision**: All outbound relays through Brevo EU (ex-Sendinblue). 300 emails/day free tier (3x Mailgun's 100/day). -- **Why migrated**: Mailgun's 100/day limit was too tight β€” the E2E probe uses ~72/day, leaving only 28 for real mail. -- **DKIM**: Brevo uses delegated DKIM via CNAME (`brevo1._domainkey`, `brevo2._domainkey`). Mailgun's `s1._domainkey` retained for the roundtrip probe (still uses Mailgun API for inbound testing). -- **Tradeoff**: Dependency on Brevo SaaS for outbound. - -### Rspamd over SpamAssassin/OpenDKIM -- **Decision**: Rspamd replaces both SpamAssassin and OpenDKIM in a single component -- **Tradeoff**: Higher memory usage (~150-200MB) but simpler stack - -### Client-IP Preservation (pfSense HAProxy + PROXY v2) -- **Current (2026-04-19, bd code-yiu)**: pfSense HAProxy listens on `10.0.20.1:{25,465,587,993}`, forwards to k8s NodePort 30125-30128 with `send-proxy-v2` on each backend connection. The mailserver pod exposes parallel listeners (2525/4465/5587/10993) that REQUIRE the PROXY v2 header, while the stock ports 25/465/587/993 stay PROXY-free for intra-cluster traffic (Roundcube, probe). The mailserver Service is ClusterIP-only; ETP is no longer a concern for external traffic. -- **Historical (2026-04-12 β†’ 2026-04-19)**: Dedicated MetalLB IP `10.0.20.202` with `externalTrafficPolicy: Local` β€” required pod/speaker colocation; kube-proxy preserved client IP only when pod was on the same node as the advertising speaker. -- **Why switched**: ETP:Local made the mailserver's single replica drop inbound mail silently during pod reschedule (30-60s GARP flip). HAProxy with `send-proxy-v2` lets the pod reschedule to any node and recover IP-preservation through the header. -- **Tradeoff**: pfSense now runs HAProxy (one more service in the firewall's responsibility); alt container ports + extra Service are ~80 lines of Terraform. The win is HA without IP-preservation compromise. -- **Runbook**: [`runbooks/mailserver-pfsense-haproxy.md`](../runbooks/mailserver-pfsense-haproxy.md). - -## Troubleshooting - -### Inbound mail not arriving -1. **DNS/MX**: `dig MX viktorbarzin.me +short` β†’ should show `mail.viktorbarzin.me` -2. **WAN reachability**: `nc -zw5 mail.viktorbarzin.me 25` from outside -3. **pfSense NAT**: verify WAN:{25,465,587,993} rdr to `10.0.20.1` (HAProxy VIP). `ssh admin@10.0.20.1 'pfctl -sn' | grep '10.0.20.1'` -4. **HAProxy health**: `ssh admin@10.0.20.1 "echo 'show servers state' | socat /tmp/haproxy.socket stdio"` β€” at least one backend in `srv_op_state=2` (UP) per pool -5. **Container listener**: `kubectl exec -n mailserver -c docker-mailserver deployment/mailserver -- ss -ltn | grep -E ':(25|2525|465|4465|587|5587|993|10993)\b'` β€” 8 lines expected -6. **Postfix queue + delivery**: `kubectl logs -n mailserver deploy/mailserver -c docker-mailserver | grep -E 'from=|reject|smtpd-proxy'` -7. **CrowdSec decisions**: `kubectl exec -n crowdsec deploy/crowdsec-lapi -- cscli decisions list` - -### Outbound mail failing -1.

Serves only what SNMP can't (indicator LED, NIC link-speed Mbps, machine/BIOS info, per-drive storage table). **HA Sofia's R730 sensors moved off this exporter to a fast Prometheus SNMP query on 2026-06-05** (see the iDRAC subsection under "How It Works"), so the `sensors` collector here is now vestigial. | - -## How It Works - -### Metrics Collection - -Prometheus scrapes metrics from all cluster components and applications using ServiceMonitor CRDs and scrape configs. Every new service deployed to the cluster receives: -1. A Prometheus scrape configuration (via ServiceMonitor or static config) -2. An Uptime Kuma HTTP monitor for internal health checks -3. An external HTTP monitor (auto-created by `external-monitor-sync` for all Cloudflare-proxied services) - -### External Monitoring - -The `external-monitor-sync` CronJob (every 10min, `stacks/uptime-kuma/`) ensures Uptime Kuma has `[External] <service>` monitors for externally-reachable ingresses. Discovery is **opt-OUT**: the script lists every ingress via the K8s API and creates a monitor for any host ending in `.viktorbarzin.me`, skipping only those annotated `uptime.viktorbarzin.me/external-monitor: "false"`. Both `ingress_factory` and the `reverse-proxy` factory emit that annotation when the caller sets `external_monitor = false`; leaving it null keeps the opt-in default (important for helm-provisioned ingresses that don't go through our factories). The legacy `cloudflare_proxied_names` ConfigMap is a fallback if the K8s API discovery fails. - -These monitors test the full external access path (DNS β†’ Cloudflare β†’ Tunnel β†’ Traefik β†’ Service) from inside the cluster. The status-page-pusher groups them as "External Reachability" and pushes a `external_internal_divergence_count` metric to Pushgateway when services are externally down but internally up. Alert `ExternalAccessDivergence` fires after 15min of divergence. - -Data flows from targets through Prometheus storage to Grafana dashboards. Applications emit logs to stdout/stderr which are aggregated by Loki and queryable through Grafana's log viewer. - -### Cluster log aggregation (Alloy β†’ Loki) + the "Cluster Logs" dashboard - -Pod logs are tailed off the nodes' `/var/log/pods` by the **Grafana Alloy** -DaemonSet (`alloy.yaml`) and shipped to Loki with labels `namespace` / `pod` / -`container` / `app`; node + external-Pi system logs arrive as the `node-journal` -and `rpi-sofia-journal` jobs (labels `node` / `unit` / `level`). - -> **Gotcha (regression found + fixed 2026-06-05):** `loki.source.file` does -> **not** expand globs. The pod-log pipeline must place a **`local.file_match`** -> component between `discovery.relabel` (which writes the -> `/var/log/pods/*<uid>/<container>/*.log` glob into `__path__`) and -> `loki.source.file`. Without it, `loki.source.file` `stat()`s the literal `*` -> path and ships **zero** pod logs β€” for a stretch only the journals reached -> Loki. A `stage.cri {}` stage parses the containerd CRI wrapper so Loki stores -> clean messages + real timestamps. If application logs ever vanish from Loki -> again, check Alloy logs for `loki.source.file ... stat failed`. On first -> discovery Alloy reads existing files from the start β†’ a brief burst of -> `entry too far behind` 400s from Loki (old lines rejected, recent accepted); -> it self-settles. Alloy read-positions are ephemeral, so a pod restart repeats -> the bounded catch-up read β€” watch sdc IO (the 2026-05-26 storm surface; mem -> limits are the safeguard). - -Search/observe everything via the **"Cluster Logs"** Grafana dashboard -(`dashboards/cluster-logs.json`, *Logs* folder): `$namespace`/`$app`/`$pod` -dropdowns + free-text regex `$search`, log-volume-by-namespace, error/warn rate, -top namespaces/pods by errors, a live filterable logs panel, and a journals row. -Error/warn panels use case-insensitive regex line-filters because pod logs carry -no `level` stream label. - -**Surfaced in ha-sofia** for Emo: two RESTful sensors -(`/config/rest_resources/loki_cluster_{errors,warnings}.yaml`) query Loki for -cluster error/warn line counts (5-min window) β†’ `sensor.cluster_log_errors_5m` / -`sensor.cluster_log_warnings_5m`, for a compact trend card on the Π‘Π°Ρ€Π·ΠΈΠ½ΠΈ status -view plus a Grafana-link button. Those sensors reach Loki via the Traefik LB IP -`10.0.20.203` + a `Host: loki.viktorbarzin.lan` header (`verify_ssl: false`) -because `loki.viktorbarzin.lan` has **no Technitium record yet** (the -`technitium-ingress-dns-sync` CronJob only creates `.me` CNAMEs + pins -`ingress.viktorbarzin.lan`). **Follow-up:** register `loki.viktorbarzin.lan` in -Technitium (or fix the `*.viktorbarzin.lan` wildcard) so both this sensor and the -Sofia-Pi promtail can resolve it by name instead of pinning the LB IP. - -### External host: rpi-sofia (Sofia Raspberry Pi) - -`rpi-sofia` is a physical Raspberry Pi 3 at the Sofia home site (not in the cluster β€” it's the Frigate camera DNAT gateway + solar-inverter path + HA MQTT sensor publisher). It is monitored **off-box** into the cluster, set up 2026-06-05 after a ~5h hang whose cause couldn't be reconstructed because the Pi's *local* journal had silently stopped writing back in April (an aging 2017 SD card intermittently flips the rootfs read-only). Everything below ships telemetry to the cluster so the **next** failure is captured centrally, surviving the SD card. - -**Metrics** β€” Prometheus static scrape job `rpi-sofia` β†’ `rpi-sofia.viktorbarzin.lan:9100` (apt `prometheus-node-exporter`). A `vcgencmd` textfile collector on the Pi (`/usr/local/bin/rpi-throttle-textfile.sh` + a 1-min systemd timer) adds Pi-specific gauges node_exporter lacks: `rpi_under_voltage_now`/`_occurred`, `rpi_throttled_now`/`_occurred`, `rpi_soc_temp_celsius`, `rpi_core_volts`. - -**Logs** β€” `promtail` v3.5.1 (armv7) on the Pi ships the **full systemd journal** to the cluster Loki via a LAN-gated ingress (`https://loki.viktorbarzin.lan/loki/api/v1/push`; see `loki_ingress.tf`, `auth = "none"` + `allow_local_access_only`). Stream selector: `{job="rpi-sofia-journal", host="rpi-sofia"}`, relabeled with `unit` and `level` (error/warning/notice/info). Coverage (~440 entries/hr): -- **Kernel / non-unit messages** (the `unit=""` / `(none)` stream) β€” `dmesg`-level lines, i.e. the `mmc`/`EXT4-fs` read-only-remount and under-voltage kernel warnings that precede a hang. This is the primary forensic signal. -- **All systemd units** β€” `prometheus-node-exporter`, `promtail`, `dnsmasq`, `cron`, `ssh`, `systemd-logind`, `avahi-daemon`, `rng-tools`, `vncserver-x11`, login `session-*.scope`, etc. - -Query examples (Grafana β†’ Loki): `{job="rpi-sofia-journal"}`, `{job="rpi-sofia-journal"} | level=~"error|warning"`, `{job="rpi-sofia-journal", unit="ssh.service"}`. - -**Dashboard** β€” `dashboards/rpi-sofia.json` ("RPi Sofia", Hardware folder): status, undervoltage/throttle, SoC temp, load, memory, root-fs free + read-only, network. - -**Alerts** (group `RPi Sofia` in `prometheus_chart_values.tpl`): `RpiSofiaDown` (`up==0`), `RpiSofiaFilesystemReadonly` (`node_filesystem_readonly{mountpoint="/"}==1` β€” the SD-failure signature), `RpiSofiaUndervoltage` (`rpi_under_voltage_occurred==1`), `RpiSofiaHighTemp`. - -**Recovery** β€” a systemd hardware watchdog (`RuntimeWatchdogSec=14s`, bcm2835 max ~15s) auto-reboots the Pi on a hard hang instead of leaving it dead for hours. - -> The cluster side (scrape job, alerts, Loki ingress, dashboard) is Terraform-managed in `stacks/monitoring/`. The **Pi-side** pieces (node_exporter, the textfile collector + timer, promtail, the watchdog config, and the `server=/viktorbarzin.lan/192.168.1.2` dnsmasq split-horizon forward needed to resolve the Loki ingress) are configured by hand on the Pi β€” it is not under Terraform β€” and are backed up off-box at `/home/wizard/rpi-sofia-backup/`. The real reliability fix (reflash/replace the SD card) needs on-site access. - -### Dell R730 iDRAC: SNMP-primary + Redfish remnant (migrated 2026-06-05) - -The R730 iDRAC (`192.168.1.4` / `idrac.viktorbarzin.lan`) is monitored by **two** Prometheus jobs, both relabeled to the `r730_idrac_*` prefix (which historically hid which source served what). Design/plan: `docs/plans/2026-06-05-idrac-snmp-migration-{design,plan}.md`. - -- **`snmp-idrac` (FAST, primary, 1m / 30s):** snmp-exporter `dell_idrac` module against `:161` (v2c, community `Public0` = `auth=public_v2`). ~3.7s/scrape. Serves all dynamic + health + alerting metrics: `r730_idrac_temperatureProbeReading` (tenths-Β°C, Γ·10), `coolingDeviceReading` (fan RPM, label `coolingDeviceLocationName`), `amperageProbeReading{amperageProbeLocationName="System Board Pwr Consumption"}` (watts), `powerSupplyCurrentInputVoltage`, `globalSystemStatus`, `systemPowerState`, `powerSupplyStatus`, `physicalDiskComponentStatus`, `systemStateMemoryDeviceStatusCombined`, etc. -- **`redfish-idrac` (SLOW remnant, 10m / 45s):** the old mrlhansen exporter, trimmed, kept only for metrics SNMP can't serve (indicator LED, NIC Mbps, machine/BIOS info, per-drive storage table). Its `sensors` collector is now **vestigial** (HA moved off it β€” see next bullet) and could be dropped. -- **HA Sofia R730 sensors β†’ Prometheus SNMP (2026-06-05):** ha-sofia's 7 REST sensors (`/config/rest_resources/idrac_redfish_exporter.yaml` β€” CPU/exhaust/inlet temp, power, 2Γ— PSU voltage, fan speed) were re-pointed from the slow on-demand Redfish exporter (`scan_interval: 120`, ~16-22s/fetch, intermittent `unavailable` blips) to a **fast Prometheus query of the SNMP values** (`scan_interval: 30`, instant): `https://prometheus-query.viktorbarzin.lan/api/v1/query?query={__name__=~"r730_idrac_…"}`, one query β†’ JSON, each sensor filters by metric+label (temps Γ·10). The `prometheus-query.viktorbarzin.lan` ingress is **local-only, `auth=none`, path-scoped to `/api/v1/query`** (added in `prometheus.tf`) so HA can query the API without the Authentik gate on `prometheus.viktorbarzin.me`. Its Technitium CNAME (β†’ `ingress.viktorbarzin.lan`) was added **manually via the API** β€” like the other `.lan` exporter hosts it is NOT auto-synced (the `technitium-ingress-dns-sync` CronJob only creates `.me` records; same gap as the Loki-sensor follow-up noted above). HA-side file is auto-version-controlled by the ha-sofia HomeAssistantVersionControl add-on; pre-migration copy saved at `/config/idrac_redfish_exporter.bak-pre-snmp`. - -**Gotchas:** -- **Enum values differ from the old Redfish metrics.** DellStatus: `3 = OK` (was Redfish `1`); `systemPowerState`: `4 = on` (was `2`). All iDRAC alert exprs were rewritten accordingly (`!= 3`, `!= 4`). -- The alert `iDRACSNMPMetricsMissing` was historically a misnomer (checked a Redfish metric); it now correctly probes `absent(r730_idrac_globalSystemStatus)`. `iDRACRedfishMetricsMissing` now probes `absent(r730_idrac_powerSupplyCurrentInputVoltage)`. -- **SSD life % + SEL are genuine SNMP gaps but were already inert** (Redfish reported `0`/empty), so the SSD-wear alerts (kept on `r730_idrac_idrac_storage_drive_life_left_percent`) and the SEL dashboard panel are unchanged. -- Why SNMP: the Redfish exporter (`metrics: all: true`) walked every subtree on each scrape β€” ~18.5s avg / 28s peak against the slow BMC β€” which forced the infrequent interval. SNMP is a single fast walk. - -### Alert Cascade Inhibition - -Alertmanager implements intelligent alert suppression to prevent alert storms during cascading failures: - -```mermaid -graph LR - NODE_DOWN[Node Down Alert] -->|Inhibits| POD_ALERTS[Pod Alerts on That Node] - COMPLETED[Completed CronJob Pod] -->|Excluded from| POD_READY[Pod Not Ready Alerts] -``` - -When a node goes down, all pod-level alerts for pods scheduled on that node are suppressed, reducing noise and focusing attention on the root cause. - -### GPU Monitoring - -NVIDIA GPU metrics are collected via dcgm-exporter with configurable resource limits (`dcgmExporter.resources`). Metrics include GPU utilization, memory usage, temperature, and power consumption. - -### Database Version Pinning - -MySQL, PostgreSQL, and Redis images have Diun monitoring disabled to prevent automatic version updates that could cause compatibility issues. Version upgrades are manual and coordinated. - -## Configuration - -### Key Config Files - -- **Monitoring Stack**: `stacks/platform/modules/monitoring/` - - Prometheus scrape configs and recording rules - - Grafana dashboard definitions - - Alertmanager routing and inhibition rules - - Uptime Kuma configuration - -### Prometheus Scrape Configs - -Every service must expose metrics and be registered in Prometheus via ServiceMonitor or static scrape config. Standard pattern: - -```yaml -apiVersion: monitoring.coreos.com/v1 -kind: ServiceMonitor -metadata: - name: my-service -spec: - selector: - matchLabels: - app: my-service - endpoints: - - port: metrics -``` - -### Grafana Dashboards - -14+ pre-configured dashboards covering: -- Kubernetes API Server -- CoreDNS -- GPU metrics -- UPS status -- Node metrics -- Pod resource usage -- Application-specific metrics - -### Alert Definitions - -#### Infrastructure Alerts -- **OOMKill**: Container killed due to out-of-memory -- **PodReplicaMismatch**: Deployment/StatefulSet replica count doesn't match desired -- **ClusterMemoryRequestsHigh**: Cluster memory requests >85% -- **ContainerNearOOM**: Container using >85% of memory limit -- **PodUnschedulable**: Pod cannot be scheduled due to resource constraints -- **CPUTemp**: CPU temperature threshold exceeded -- **SSDWrites**: Excessive SSD write volume -- **NFSResponsiveness**: NFS mount latency issues -- **UPSBattery**: UPS battery charge low - -#### Application Alerts -- **4xx/5xx Error Rates**: HTTP error rate threshold exceeded - -#### Email Monitoring Alerts -- **EmailRoundtripFailing**: E2E email probe returning failure for >30m -- **EmailRoundtripStale**: No successful email round-trip in >80m (60m threshold + for:20m) -- **EmailRoundtripNeverRun**: Email probe has never reported (40m) - -#### Registry Integrity Alerts -- **RegistryManifestIntegrityFailure**: Private registry serving 404 for manifests it advertises (orphan OCI-index children) β€” fires after 30m of `registry_manifest_integrity_failures > 0`. Remediation: rebuild affected image per `docs/runbooks/registry-rebuild-image.md`. -- **RegistryIntegrityProbeStale**: Probe hasn't reported in >1h (CronJob broken) -- **RegistryCatalogInaccessible**: Probe cannot fetch `/v2/_catalog` (auth failure or registry down) - -#### Immich Smart Search Alerts -- **ImmichSmartSearchSlow**: Representative context-search ANN query >1s for 15m. Root cause is almost always the `clip_index` (vchord, ~665MB) decaying out of PG `shared_buffers` β€” a cold list read is ~1.8s vs ~4ms warm. Remediation: confirm the `clip-index-prewarm` CronJob (immich ns, `*/5`) is succeeding; manual fix `kubectl exec -n immich -c immich-postgresql <pg-pod> -- psql -U postgres -d immich -c "SELECT pg_prewarm('clip_index')"`. -- **ImmichClipIndexColdCache**: `clip_index` <50% resident in shared_buffers for 15m (leading indicator; same remediation). -- **ImmichSearchProbeStale**: `immich-search-probe` hasn't reported in >30m (CronJob broken). Inhibits the two above so frozen Pushgateway gauges don't false-fire. - -The Immich smart-search monitoring uses two CronJobs in the `immich` namespace (both `*/5`): `clip-index-prewarm` re-runs `pg_prewarm('clip_index')` to keep the vector index hot during runtime (the `postStart` prewarm only fires at pod start; `pg_prewarm.autoprewarm` only reloads at startup, so the index otherwise decays under job buffer-pressure), and `immich-search-probe` (postgres init-container measures a random-vector ANN latency + `pg_buffercache` residency β†’ curl sidecar pushes `immich_smart_search_db_seconds` / `immich_clip_index_cached_pct` / `immich_smart_search_probe_success` / `immich_smart_search_probe_last_run_timestamp` to the Pushgateway). Also surfaced by cluster-health check #46 (`check_immich_search`). Note this is the **Postgres** half of smart-search warmth; the **ML model** half is kept warm by the separate `clip-keepalive` CronJob. - -The email monitoring system uses a CronJob (`email-roundtrip-monitor`, every 10 min) in the `mailserver` namespace that: -1. Sends a test email via Mailgun HTTP API to `smoke-test@viktorbarzin.me` -2. Email lands in the `spam@` catch-all mailbox via MX delivery -3. Verifies delivery via IMAP (searches by UUID marker in subject) -4. Deletes the test email immediately -5. Pushes metrics (`email_roundtrip_success`, `email_roundtrip_duration_seconds`, `email_roundtrip_last_success_timestamp`) to Prometheus Pushgateway -6. Pushes status to Uptime Kuma E2E Push monitor - -Uptime Kuma monitors: TCP SMTP (port 25) on `176.12.22.76` (external), IMAP (port 993) on `10.0.20.202`, and Dovecot exporter metrics on port 9166. - -#### Security Alerts (Wave 1 β€” planned, beads `code-8ywc`) - -Routed via **Loki ruler β†’ Alertmanager β†’ `#security` Slack receiver**. Same handling path as infra alerts. Single channel with severity labels inside (critical/warning/info), not three separate channels. Detection sources: K8s API audit log (`job=kube-audit`), Vault audit log (`job=vault-audit`), PVE sshd journald (`job=sshd-pve`), Calico flow logs (`job=calico-flow`, W1.6 only). - -| # | Source | Event | Severity | -|---|---|---|---| -| K2 | kube-audit | SA token used from outside cluster | critical | -| K3 | kube-audit | Secret read in vault/sealed-secrets/external-secrets by non-allowlisted SA | critical | -| K4 | kube-audit | Exec into vault/kube-system/dbaas/cnpg-system pod by non-allowlisted user | warning | -| K5 | kube-audit | Mass delete (>5 Pod/Secret/CM in 60s) | critical | -| K6 | kube-audit | Audit policy itself modified | critical | -| K7 | kube-audit | New `*,*` ClusterRole created | warning | -| K8 | kube-audit | Anonymous binding granted | critical | -| K9 | kube-audit | `me@viktorbarzin.me` request from non-allowlist sourceIP | critical | -| V1 | vault-audit | Root token created | critical | -| V2 | vault-audit | Audit device disabled/modified | critical | -| V3 | vault-audit | Seal status changed | critical | -| V4 | vault-audit | Policy written/modified (allowlist Terraform actor) | warning | -| V5 | vault-audit | Auth failure spike >10/min | warning | -| V6 | vault-audit | Token with policies different from parent created | critical | -| V7 | vault-audit | Viktor's entity_id from non-allowlist remote_addr (requires `x_forwarded_for_authorized_addrs`) | critical | -| S1 | sshd-pve | sshd auth success from non-allowlist IP | critical | - -K1 (cluster-admin grant) intentionally skipped β€” see security.md. - -Allowlist source-IP CIDRs (used by K2, K9, V7, S1): `10.0.20.0/22`, `192.168.1.0/24`, K8s pod CIDR, K8s service CIDR, Headscale tailnet. Policy: no public-IP access; all admin paths transit LAN or Headscale. - -IOPS impact estimated ~1-2 GB/day additional disk writes after custom audit-policy tuning. Retention: 90d for security streams. - -##### Authentik walling-off guard β€” `AuthentikWallingOffPublicPath` - -Detects the inverse of the K-series alerts: a service that **must work WITHOUT Authentik SSO** getting accidentally walled off. Services on `ingress_factory auth = "required"` put Authentik forward-auth on `/`, which 302-bounces native-client / public / webhook / WebSocket / SPA-XHR paths. We carve those out with path-scoped `auth = "none"` ingresses; a TF revert, a bad deploy, or `ingress_factory`'s fail-closed `auth` default flipping back to `"required"` can silently clobber a carve-out. - -- **Mechanism**: `blackbox-exporter` (monitoring ns) probes a representative GET-able URL per carve-out with `no_follow_redirects: true`. The `http_no_authentik_redirect` module FAILS the probe (`fail_if_header_matches` on the `Location` header, regex `authentik\.viktorbarzin\.me|/outpost\.goauthentik\.io|/application/o/authorize`) iff the response redirects to Authentik. `valid_status_codes` enumerates all expected non-Authentik responses **including 301/302** (so a legitimate redirect, e.g. a short-link 302, or a 404 carve-out like meshcentral `/agent.ashx`, stays green). Scrape job: `blackbox-authentik-walloff` (1m). -- **Alert**: `probe_failed_due_to_regex{job="blackbox-authentik-walloff"} == 1` for 10m β†’ `severity=warning`, `lane=security` β†’ **`#security` Slack** (Slack-only, no paging). `probe_failed_due_to_regex` (not bare `probe_success==0`) is the signal: it isolates the Authentik-redirect from unrelated 5xx/DNS/TLS failures already covered by reachability alerts. Inhibited by `TraefikDown` and `AuthentikDown` (symptom, not regression, during those outages). -- **Target list + how to add one**: `local.authentik_walloff_targets` in `stacks/monitoring/modules/monitoring/authentik_walloff_probe.tf` β€” a map of `service β†’ URL`.

A finite `writeTimeout` truncates *any* download that runs longer than it, regardless of progress. A prior `writeTimeout=60s` silently cut large Immich video downloads at the 60s mark (HTTP/2 stream reset). `writeTimeout=0` (Traefik's default) is required for unlimited-size downloads β€” Immich's own Traefik reverse-proxy guidance assumes it and never sets `writeTimeout`. `readTimeout` is kept finite (not 0) because an unbounded request read is the slow-loris vector; 3600s passes multi-GB uploads while keeping a backstop (Immich has no resumable upload, so the window must exceed real upload times). Single-asset downloads (`GET /api/assets/{id}/original`) serve `206 Partial Content`, so they are also resumable on a dropped connection; on-the-fly ZIP "download all" is not (no stable byte offsets). - -### MetalLB & Load Balancing - -MetalLB v0.15.3 allocates IPs from `10.0.20.200-10.0.20.220` (21 IPs) in **Layer 2 mode**; **four are in use**. Most LoadBalancer services share **10.0.20.200** (`metallb.io/allow-shared-ip: shared`, `externalTrafficPolicy: Cluster`). **Three services hold dedicated IPs with `externalTrafficPolicy: Local`** to preserve the real client source IP (and, for Traefik, to make QUIC/HTTP3 work β€” a shared IP forbids the mixed ETP the UDP listener needs). - -> **Why not consolidate to fewer IPs?** The three dedicated IPs can't be merged. MetalLB L2 only lets `ETP=Local` services share an IP if they have *identical pod selectors* (Traefik/KMS/Technitium don't), and a shared `ETP=Local` IP announces from a single node β€” blackholing any service whose pods aren't on it. Traefik additionally can never leave a dedicated IP (QUIC needs the UDP listener on its own ETP=Local IP). Merging would cost client-IP preservation or HA, so the 4-IP layout is deliberate β€” not sprawl.

Management traffic (Proxmox, DevVM) stays on VLAN 10, K8s workloads stay on VLAN 20. Failures in K8s don't affect access to Proxmox or storage. - -### Why Cloudflared Tunnel Instead of Port Forwarding? - -**Alternatives considered**: -1. **Traditional port forwarding (80/443)**: Exposes public IP, requires firewall rules, DDoS risk. -2. **VPN-only access**: Limits accessibility for public services like blog. - -**Decision**: Cloudflared tunnel provides: -- No public IP exposure -- DDoS protection via Cloudflare -- TLS termination at Cloudflare edge -- Zero firewall configuration -- Works behind CGNAT - -### Why Split DNS (Technitium + Cloudflare)? - -**Alternatives considered**: -1. **Cloudflare only**: Works but introduces external dependency for internal resolution. -2. **Technitium only**: Can't handle public domains without zone delegation. - -**Decision**: Technitium handles internal `.lan` domains with near-zero latency. Cloudflare handles public domains with global DNS. K8s nodes use Technitium as primary, which forwards non-.lan queries to Cloudflare. - -### Why Fail-Open on CrowdSec Bouncer? - -**Alternatives considered**: -1. **Fail-closed**: Maximum security, but LAPI downtime blocks all traffic. -2. **Redundant LAPI**: Already scaled to 3 replicas, but resource pressure can still cause outages. - -**Decision**: Availability > strict bot blocking. CrowdSec LAPI is scaled to 3 replicas for resilience, but during cluster-wide resource exhaustion (e.g., memory pressure), bouncer falls back to allowing traffic. This prevents a complete service outage due to a security add-on. - -### Why HTTP/3 (QUIC)? - -**Benefit**: Reduces latency on lossy connections (mobile, Wi-Fi) and enables multiplexing without head-of-line blocking. Minimal overhead since Traefik handles it natively. - -### Why Pull-Through Registry Cache? - -**Problem**: Docker Hub rate limits (100 pulls/6h for anonymous, 200 pulls/6h for free accounts) caused CI/CD failures. - -**Solution**: Local registry cache at 10.0.20.10 mirrors all pulls. Containerd transparently redirects requests. Zero application changes needed. - -**Trade-off**: Stale `:latest` tags β€” requires discipline to use versioned tags (8-char git SHAs for app images). - -## Troubleshooting - -### Ingress Returns 502 Bad Gateway - -**Symptoms**: Cloudflared tunnel is up, Traefik logs show `dial tcp: lookup <service> on 10.0.20.201:53: no such host`. - -**Diagnosis**: DNS resolution failed. Check: -1. Is Technitium pod running? `kubectl get pod -n technitium` -2. Can nodes resolve the service? `kubectl exec -it <any-pod> -- nslookup <service>.viktorbarzin.lan` -3. Is the Service correctly created? `kubectl get svc -n <namespace>` - -**Fix**: If Technitium is down, restart it. If the Service is missing, check Terraform apply status. - -### Traefik Shows "Service Unavailable" for All Requests - -**Symptoms**: All ingress routes return 503, Traefik dashboard shows no backends available. - -**Diagnosis**: Middleware chain is blocking traffic. Check: -1. Authentik status: `kubectl get pod -n authentik` -2. CrowdSec LAPI status: `kubectl get pod -n crowdsec` -3. Traefik logs: `kubectl logs -n kube-system deploy/traefik` - -**Fix**: If Authentik is down and ingress uses forward-auth, pods won't pass health checks. Scale Authentik to 3 replicas or temporarily disable forward-auth middleware. - -### MetalLB Doesn't Assign IP to LoadBalancer Service - -**Symptoms**: Service stays in `<pending>` state, no IP assigned. - -**Diagnosis**: Check MetalLB logs: `kubectl logs -n metallb-system deploy/controller` - -**Common causes**: -1. **IP pool exhausted**: 21 IPs available (10.0.20.200-10.0.20.220), check `kubectl get svc -A | grep LoadBalancer` -2. **Missing allow-shared-ip annotation**: Services must have `metallb.io/allow-shared-ip: shared` and `metallb.io/loadBalancerIPs: 10.0.20.200` -3. **Mismatched externalTrafficPolicy**: All services sharing an IP must use the same ETP (currently `Cluster`). Error: "can't change sharing key" -4. **MetalLB controller crash-looping**: Resource limits too low - -**Fix**: If pool exhausted, either delete unused Services or expand the IPAddressPool CRD. For sharing key errors, ensure new services use `externalTrafficPolicy: Cluster` and both `metallb.io/` annotations. - -### DNS Resolution Loops (Technitium β†’ Cloudflare β†’ Technitium) - -**Symptoms**: Slow DNS responses, `dig` shows multiple CNAMEs in a loop. - -**Diagnosis**: Misconfigured forwarder or zone overlap. - -**Fix**: Ensure Technitium forwards all non-.lan queries to Cloudflare (1.1.1.1), and Cloudflare zones don't contain `.lan` records. - -### Cloudflared Tunnel Disconnects Frequently - -**Symptoms**: Intermittent 502 errors, Cloudflared logs show `connection lost, retrying`. - -**Diagnosis**: Check: -1. Network stability: `ping 1.1.1.1` from a K8s node -2. Cloudflared resource limits: `kubectl top pod -n cloudflared` -3. Cloudflare tunnel status in dashboard - -**Fix**: If resource-limited, increase memory/CPU. If network-related, check pfSense logs for NAT table exhaustion or ISP issues. - -### Rate Limiter Blocks Legitimate Traffic - -**Symptoms**: Users report 429 errors during normal usage (e.g., Immich uploads). - -**Diagnosis**: Check Traefik middleware config for the affected IngressRoute. - -**Fix**: Increase rate limit in `ingress_factory` module. Default is 100 req/min per IP. Immich and Nextcloud use 500 req/min. - -### Large Downloads or Uploads Truncate / Fail Partway - -**Symptoms**: Large file transfers (e.g. Immich videos, Nextcloud sync) fail at a consistent wall-clock point regardless of file β€” a download stops at exactly N seconds Γ— throughput bytes; an upload fails ~1 min in. Browser shows "network error"; `curl` exits 18/92 (truncated / HTTP/2 stream reset). - -**Diagnosis**: Check the `websecure` entrypoint `respondingTimeouts` (see Entrypoint Transport Timeouts). These are **hard total-duration caps**, not idle timeouts β€” a finite `writeTimeout` cuts downloads, a finite `readTimeout` cuts uploads, both regardless of progress. Reproduce deterministically: `curl --limit-rate 6M` a file large enough to exceed the cap; it dies at the cap. - -**Fix**: `writeTimeout=0` (unlimited downloads), `readTimeout` β‰₯ longest expected upload (currently `3600s`). Not Cloudflare (Immich is non-proxied) and not the pfSense IPv6 bridge (its 1h timeouts are inactivity-based). - -## Related - -- **Runbooks**: - - `docs/runbooks/restart-traefik.md` - - `docs/runbooks/reset-crowdsec-bans.md` - - `docs/runbooks/add-dns-record.md` -- **Architecture Docs**: - - `docs/architecture/dns.md` β€” DNS architecture (Technitium, CoreDNS, Cloudflare, Split Horizon) - - `docs/architecture/vpn.md` β€” VPN and remote access - - `docs/architecture/storage.md` β€” NFS and iSCSI architecture (coming soon) -- **Reference**: - - `.claude/reference/service-catalog.md` β€” Full service inventory - - `.claude/reference/proxmox-inventory.md` β€” VM and LXC details diff --git a/docs/architecture/overview.md b/docs/architecture/overview.md deleted file mode 100644 index 5ca53660..00000000 --- a/docs/architecture/overview.md +++ /dev/null @@ -1,319 +0,0 @@ -# Infrastructure Overview - -## Overview - -This homelab infrastructure runs a production-grade Kubernetes cluster on Proxmox, hosting 70+ services including web applications, databases, monitoring, security, and GPU-accelerated workloads.

Proxmox VE provides hypervisor capabilities with hardware passthrough support for the Tesla T4 GPU. The physical network interface (eno1) bridges to vmbr0 for physical network access, while vmbr1 provides VLAN-aware internal networking. - -### Network Layer - -pfSense (VMID 101) acts as the central gateway and firewall, routing traffic between: -- Physical network (192.168.1.0/24) via vmbr0 -- Management VLAN 10 (10.0.10.0/24) via vmbr1:vlan10 -- Kubernetes VLAN 20 (10.0.20.0/24) via vmbr1:vlan20 - -This three-tier network design isolates Kubernetes workloads from management infrastructure and provides controlled access to the physical network. - -### Compute Layer - -The Kubernetes cluster consists of 7 nodes: -- **k8s-master (200)**: 8c/32GB control plane running kube-apiserver, etcd, controller-manager -- **k8s-node1 (201)**: 16c/48GB GPU node with Tesla T4 passthrough, tainted for GPU workloads only -- **k8s-node2-6 (202-206)**: 8c/32GB workers running general-purpose workloads - -GPU passthrough on node1 uses PCIe device 0000:06:00.0. The NVIDIA GPU Operator's gpu-feature-discovery auto-labels whichever node carries the card with `nvidia.com/gpu.present=true`; `null_resource.gpu_node_config` taints the same set of nodes with `nvidia.com/gpu=true:PreferNoSchedule`. No hostname is hardcoded β€” moving the card to a different node requires no Terraform edits. - -### Service Organization - -Services are organized into 70+ individual Terraform stacks under `stacks/<service>/`. Each service belongs to a tier, which determines: -- Resource limits and quotas -- Scheduling priority (higher tier = preempts lower) -- Default container resources -- QoS class (Guaranteed for tiers 0-2, Burstable for 3-4) - -Kyverno policies automatically inject namespace labels, LimitRange, ResourceQuota, and PriorityClass based on the namespace tier prefix. - -### Key Services - -**Critical Services (Tier 0-1)**: -- **Traefik**: Ingress controller with automatic HTTPS (Let's Encrypt) -- **Authentik**: SSO/OIDC provider for all services -- **Vault**: Secrets management with auto-unseal -- **Cloudflared**: Cloudflare Tunnel for external access -- **Technitium**: Internal DNS server -- **Headscale**: Tailscale-compatible mesh VPN control plane - -**Storage & Security**: -- **Proxmox NFS**: NFS storage served directly from Proxmox host (192.168.1.127) at `/srv/nfs` (HDD) and `/srv/nfs-ssd` (SSD) -- **Proxmox CSI**: Block storage via LVM-thin hotplug for databases -- **Vaultwarden**: Password manager -- **Immich**: Photo management -- **CrowdSec**: IPS/IDS with community threat intelligence -- **Kyverno**: Policy engine for admission control - -**Monitoring & Observability**: -- **Prometheus**: Metrics collection -- **Grafana**: Visualization and dashboards -- **Loki**: Log aggregation -- **Alertmanager**: Alert routing - -**Application Services**: Woodpecker CI, Gitea, PostgreSQL, MySQL, Redis, Ollama, ComfyUI, Stable Diffusion, Freshrss, and 50+ more services. - -## Configuration - -### Key Files - -| Path | Purpose | -|------|---------| -| `stacks/<service>/terragrunt.hcl` | Individual service configuration | -| `modules/kubernetes/ingress_factory/` | Shared factory module: ingress + middleware chain + DNS + Uptime-Kuma monitor | -| `modules/kubernetes/nfs_volume/` | Shared factory module: RWX NFS PV/PVC provisioning | -| `base.hcl` | Global Terragrunt configuration | -| `terraform.tfvars` | Global variables (git-ignored) | - -### Terraform Organization - -Each service lives in `stacks/<service>/` with its own Terragrunt configuration.

Anything else fires an alert. - -#### Why no canary tokens - -Original plan included canary tokens (fake K8s Secret, Vault KV path, PVE file, sinkhole hostname). Rejected because Viktor routinely greps `secret/viktor` (135 keys) and lists `kubectl get secret -A` β€” any read-trigger canary self-fires. Use-based canaries (zero-RBAC SA tokens with audit alerts on use) were also considered but rejected in favor of cleaner source-IP anomaly detection (K9, V7) on REAL tokens β€” same threat model, no fake-token operational burden. - -#### Why no K1 (cluster-admin grant detection) - -Viktor opted out. Gap covered indirectly by K7 (new `*,*` ClusterRole created), K8 (anonymous binding), and K3 (secret read on Vault namespace) β€” most attacker progressions toward cluster-admin trigger one of these. - -#### IOPS / disk-wear - -Custom audit policy reduces volume ~80-90% vs default Metadata-everywhere. Loki tuned for fewer larger chunks: `chunk_target_size: 1.5MB`, `chunk_idle_period: 30m`, snappy compression. Retention 90d for security streams (matches Technitium DNS query log precedent). Net estimate: ~1-2 GB/day additional disk writes after tuning. - -### NetworkPolicy Default-Deny Egress (Wave 1 β€” observe-then-enforce, tier 3+4) - -Beads: `code-8ywc` W1.6 + W1.7. **Status: planned.** - -**Approach (Ξ³): cluster-wide observe-then-enforce.** - -1. **Week 0:** Enable Calico flow logs cluster-wide. Apply a GlobalNetworkPolicy with selector `tier in {tier-3, tier-4}`, `action: Log` (no Deny). Ship flow logs to Loki. -2. **Week 1:** Build per-namespace egress allowlist from observed traffic. Common allowlist module `tier3_egress_baseline` covers DNS, NTP, internal Vault/ESO/Authentik, Brevo SMTP, Cloudflare API, OAuth providers. Per-namespace add-ons for service-specific external destinations. -3. **Week 2-3:** Apply default-deny + allowlist per-namespace, starting `recruiter-responder` (smallest egress footprint β€” local llama-cpp). Watch 24-48h per namespace, iterate. Roll out 3-5 namespaces/day. - -**Scope exclusions:** tier 0/1/2 namespaces (defer to wave 2), 31 critical infra namespaces (same exclude list as Kyverno). - -**DNS handling:** Calico GlobalNetworkPolicy supports domain-based rules via the `domains:` selector which queries CoreDNS internally.

The slot is freed regardless β€” orphans consume thin-pool space, not LUN slots. - -All services storing sensitive data were migrated to `proxmox-lvm-encrypted` on 2026-04-15. This eliminates the previous double-CoW (ZFS + LVM-thin) path and ensures data-at-rest encryption. - -**NFS storage (Proxmox host)**: ~100 NFS shares for media libraries (Immich, audiobookshelf, servarr, navidrome), backup targets (`*-backup/` directories), and app data are served directly from the Proxmox host at `192.168.1.127`. Two NFS export roots exist: -- **HDD NFS**: `/srv/nfs` on ext4 LV `pve/nfs-data` (4TB) β€” bulk media and backup targets -- **SSD NFS**: `/srv/nfs-ssd` on ext4 LV `ssd/nfs-ssd-data` (100GB) β€” high-performance data (Immich ML) - -Both `StorageClass: nfs-truenas` and `StorageClass: nfs-proxmox` point to the Proxmox host and are functionally identical. The `nfs-truenas` name is historical β€” it was retained because StorageClass names are immutable on bound PVs (48 PVs reference it) and renaming would force mass PV churn across the cluster. - -**Backup storage (sda)**: 1.1TB RAID1 SAS disk, VG `backup`, LV `data` (ext4), mounted at `/mnt/backup` on PVE host. Dedicated backup disk for weekly PVC file backups, auto SQLite backups, pfSense backups, and PVE config. NFS data syncs directly to Synology via inotify change tracking (not stored on sda). Independent of live storage (sdc). - -**History (2026-04-02)**: iSCSI block volumes migrated from democratic-csi (TrueNAS iSCSI β†’ ZFS β†’ LVM-thin) to Proxmox CSI (direct LVM-thin hotplug). democratic-csi iSCSI driver removed. - -**History (2026-04-13)**: TrueNAS (VM 9000, 10.0.10.15) fully decommissioned. NFS storage migrated to the Proxmox host (192.168.1.127). ZFS datasets under `/mnt/main/` and `/mnt/ssd/` moved to ext4 LVs at `/srv/nfs/` and `/srv/nfs-ssd/`. Legacy PVs referencing `/mnt/main/` paths still work (bind-mounted or symlinked on the Proxmox host); new PVs use `/srv/nfs/` and `/srv/nfs-ssd/`.

See `docs/plans/2026-06-05-block-storage-harden-nfs-design.md`. Migrated 5 non-DB, embedded-DB-free workloads off block to NFS to relieve the per-VM LUN cap: **tandoor** (media, PG-backed), **speedtest** (config, MySQL), **hackmd** (image uploads, MySQL β€” dropped LUKS for low-sensitivity images), **changedetection** (JSON datastore), **send** (upload blobs, Redis). Freed 5 SCSI-LUN slots (4 on the then-hot node6, 21β†’16). Each followed the scale-0 β†’ busybox mover (`cp -a`) β†’ swap `claim_name` β†’ delete block PVC pattern. (Phase-1 follow-on 2026-06-05: insta2spotify also migrated β€” note its reschedule re-pulled a 3.26 GB image, a ~6 min blip; large-image services incur a pull-delay when a migration moves the pod to a fresh node.) - -**The "harden" half is now SHIPPED (2026-06-05):** -- **Orphan cleanup** β€” removed 67 `Released` proxmox PVs + 475 orphan LVs/snapshots (VG `pve` 997 β†’ ~410 LVs; thin pool freed). 1 LV left (`f127a41c`, stuck-open stale qemu fd β€” harmless, clears on node reboot; do not force `dmsetup remove`). -- **Ghost-loop prevention** β€” `csi-ghost-reconcile` CronJob (`stacks/proxmox-csi/ghost-reconcile.tf`, every 15 min) compares each worker VM's real scsi disks (Proxmox API, scoped CSI token) against k8s VolumeAttachments and safely detaches ghosts (`PUT .../config delete=scsiN`); detection mirrors check #47, with a 60 s re-confirm + per-run cap-5. Verified live (66 VAs, 0 ghosts). This closes the doom loop by construction β€” **beads `code-dfjn` can be retired.** -- **Cap deliberately kept at 28** (NOT lowered to 24): the labeler value (`stacks/proxmox-csi/.../main.tf` `node_labels`) was raised 24β†’28 per the 2026-05-25 eviction-cascade post-mortem; lowering it would reverse that fix.

Verify: `showmount -e 192.168.1.127` - -## Decisions & Rationale - -### Why NFS for Most Workloads? - -- **Simplicity**: No volume provisioning delays, instant mounts -- **RWX support**: Multiple pods can share one volume (Nextcloud, Immich) -- **Good enough**: For SQLite on NFS specifically, we accept the risk for low-value data (logs, caches) but mandate proxmox-lvm for critical DBs - -### Why Proxmox CSI for Databases? (formerly iSCSI) - -- **ACID guarantees**: Block device + local filesystem = real fsync -- **Performance**: No NFS protocol overhead for random I/O, no network hop (LVM-thin hotplug direct to VM) -- **Tested**: PostgreSQL CNPG and MySQL InnoDB Cluster both run on proxmox-lvm, zero corruption -- **Single CoW layer**: LVM-thin only, no ZFS double-CoW issues - -### Why Soft Mount for NFS? - -Hard mounts with default `timeo=600` (10 minutes) cause: -- 10-minute pod startup delays if NFS server is unreachable -- `kubectl delete pod` hangs for 10 minutes -- Kernel task hangs blocking node operations - -Soft mount (`soft,timeo=30,retrans=3`) trades availability for responsiveness: -- Max 90s hang (30s Γ— 3 retries) -- Operations return EIO after timeout β†’ app can handle error -- Acceptable for non-critical data paths - -**Critical paths**: Databases use proxmox-lvm (not NFS), so soft mount never affects data integrity. - -## Troubleshooting - -### NFS Mount Hangs - -**Symptom**: Pod stuck in `ContainerCreating`, `df -h` hangs on NFS mount - -**Diagnosis**: -```bash -# On K8s node -mount | grep nfs -showmount -e 192.168.1.127 - -# Check NFS server (Proxmox host) -ssh root@192.168.1.127 -ls -la /srv/nfs/<service> -cat /etc/exports | grep <service> -``` - -**Fix**: -1. Verify directory exists: `ls /srv/nfs/<service>` (or `/srv/nfs-ssd/<service>`) -2. Verify export: `grep <service> /etc/exports` -3. If missing: add to `/etc/exports` and run `exportfs -ra` -4. Restart NFS server: `systemctl restart nfs-server` - -### ~~iSCSI Session Drops~~ (HISTORICAL β€” iSCSI removed) - -> iSCSI was replaced by Proxmox CSI (2026-04-02) and TrueNAS has been decommissioned. This section is kept for historical reference only. - -### SQLite Corruption on NFS - -**Symptom**: `database disk image is malformed`, checksum errors - -**Diagnosis**: -```bash -# In pod -sqlite3 /data/db.sqlite "PRAGMA integrity_check;" -``` - -**Fix**: Migrate to proxmox-lvm -1. Create proxmox-lvm PVC in Terraform stack -2. Restore from backup to new volume -3. Update deployment to use new PVC -4. Delete old NFS PVC - -### Slow NFS Performance - -**Symptom**: High latency on file operations, `iostat` shows NFS wait times - -**Diagnosis**: -```bash -# On Proxmox host -ssh root@192.168.1.127 -iostat -x 5 -lvs --reportformat json pve/nfs-data ssd/nfs-ssd-data - -# On K8s node -nfsiostat 5 -``` - -**Optimization**: -1. Move hot data to SSD NFS: relocate from `/srv/nfs/<service>` to `/srv/nfs-ssd/<service>` and update PV path -2. Tune NFS mount: add `rsize=1048576,wsize=1048576` to StorageClass `mountOptions` - -## Nextcloud as PVE-NFS browser - -Both NFS export roots are mounted into the Nextcloud server pod β€” `/srv/nfs` at `/mnt/pve-nfs` and `/srv/nfs-ssd` at `/mnt/pve-nfs-ssd` β€” via standard NFS PVs (`nfs_volume` module). No host-level Unix user/group setup; Nextcloud is the sole household-facing surface. - -**ACL model β€” two patterns:** - -- **Root browser mounts** (`PVE NFS Pool`, `PVE NFS-SSD Pool`): scoped to NC group `admin`. Used by Viktor for ad-hoc browsing of any cluster NFS state. Other users never see these mounts. -- **Per-archive mounts** (e.g. `/anca-elements` β†’ `/mnt/pve-nfs/anca-elements`): one NC External mount per archive, `applicable_users` set to the archive owners. Users see only the mounts assigned to them. Write/delete access is implicit at the OS level (NC pod writes via `no_root_squash`); deny semantics come from mount visibility β€” if the mount is not in your list, you cannot reach the path. - -**Why mount-level ACL, not Files Access Control**: NC 30/31's workflow engine check classes are `FileName` (basename), `FileMimeType`, `FileSize`, `FileSystemTags`, and `UserGroupMembership`. There is no `FilePath` and no `UserId` check class. Per-(directory, user) rules are not expressible via FAC. Mount-level ACL via `occ files_external:applicable` is the supported primitive and maps cleanly onto the model. - -**Manifest**: `kubernetes_config_map_v1.nextcloud_external_storage_manifest` in `stacks/nextcloud/external_storage.tf`. Mount entries reference NC usernames (`admin`, `anca`, `emo` β€” not display names; admin is Viktor). JSON shape: -```json -{ - "rootMounts": [ - { "mountPoint": "/PVE NFS Pool", "dataDir": "/mnt/pve-nfs", "applicableGroup": "admin", "enableSharing": true }, - { "mountPoint": "/PVE NFS-SSD Pool", "dataDir": "/mnt/pve-nfs-ssd", "applicableGroup": "admin", "enableSharing": true } - ], - "archiveMounts": [ - { "mountPoint": "/anca-elements", "dataDir": "/mnt/pve-nfs/anca-elements", "applicableUsers": ["anca", "admin"], "applicableGroups": [], "enableSharing": false } - ] -} -``` -A one-shot K8s bootstrap Job applies the manifest idempotently on every `tg apply` via `occ files_external:*`, `occ files_external:applicable`, and `occ files_external:option`. `enableSharing: true` lets admin re-share a subfolder of the mount with another NC user/group/public link; default is `false` (NC's local-backend default). - -**Adding a new archive**: drop the directory under `/srv/nfs/<name>/` on PVE, append an `archiveMounts` entry to the manifest, then `scripts/tg apply` the nextcloud stack. See `docs/runbooks/nextcloud-add-archive.md` for the full step-by-step. - -**Trade-off**: a compromised NC admin account has destructive reach over the cluster NFS roots (admin sees the root browser mounts). Accepted β€” Viktor's account is the single high-value target either way. No lateral movement to databases or block PVCs via this path (those are not NFS). - -**Backup**: Synology retains a frozen copy of each archive (3-2-1 coverage); the existing `offsite-sync-backup` pipeline provides nightly delta sync from `/srv/nfs/<archive>` β†’ Synology `nfs/`. - -## Related - -- **Runbooks**: - - `docs/runbooks/restore-postgresql.md` - - `docs/runbooks/restore-mysql.md` - - `docs/runbooks/recover-nfs-mount.md` - - `docs/runbooks/nextcloud-add-archive.md` -- **Architecture**: `docs/architecture/backup-dr.md` (backup strategy using LVM snapshots and Proxmox host scripts) -- **Reference**: `.claude/reference/service-catalog.md` (which services use NFS vs proxmox-lvm) diff --git a/docs/architecture/vpn.md b/docs/architecture/vpn.md deleted file mode 100644 index 82491f99..00000000 --- a/docs/architecture/vpn.md +++ /dev/null @@ -1,445 +0,0 @@ -# VPN & Remote Access Architecture - -Last updated: 2026-04-10 - -## Overview - -Remote access to the homelab is provided through a hybrid VPN architecture: WireGuard site-to-site tunnels connect physical locations (Sofia, London, Valchedrym), while Headscale (self-hosted Tailscale control server) provides mesh overlay networking for roaming clients.

A single WireGuard interface (`tun_wg0`) on pfSense carries both peers on the `10.3.2.0/24` tunnel subnet: - -- **Sofia** (hub): `10.3.2.1` β€” pfSense, K8s cluster on `10.0.20.0/24`, management on `10.0.10.0/24`, LAN on `192.168.1.0/24` -- **London** (spoke): `10.3.2.6` β€” GL-iNet Flint 2 (GL-MT6000), LAN `192.168.8.0/24`, guest `192.168.9.0/24` -- **Valchedrym** (spoke): `10.3.2.5` β€” OpenWRT router, LAN `192.168.0.0/24` - -Routes are configured as static routes on pfSense. London and Valchedrym route Sofia-bound traffic through their WireGuard tunnels. London ↔ Valchedrym traffic transits through Sofia (no direct tunnel). - -**Use cases**: -- Replication of Vault data between Sofia and London -- Offsite database replicas -- Accessing Proxmox hosts across locations - -### Headscale Mesh Overlay - -Headscale is a self-hosted alternative to Tailscale's commercial control plane. It provides: -- **Mesh networking**: Clients establish direct WireGuard connections to each other (peer-to-peer). -- **NAT traversal**: DERP relays provide connectivity when direct connections fail. -- **OIDC authentication**: Users log in via Authentik, no pre-shared keys. -- **ACL policies**: Fine-grained control over which clients can reach which destinations. - -**Client onboarding**: -1. User installs Tailscale client (official macOS/iOS/Android app) -2. Runs: `tailscale login --login-server https://headscale.viktorbarzin.me` -3. Browser opens to Authentik SSO login -4. After successful login, Tailscale presents a registration URL -5. Admin approves the device via `headscale nodes register --user <username> --key <key>` -6. Client is added to the mesh, receives IP in 100.64.0.0/10 range - -**Connectivity test**: `ping 10.0.20.100` (Sofia K8s API server) verifies full access to the homelab network. - -### DERP Relay for NAT Traversal - -**Problem**: Symmetric NAT or restrictive firewalls prevent direct WireGuard connections between clients. - -**Solution**: Headscale runs an embedded DERP relay server (region 999, named "Home DERP"). DERP is Tailscale's NAT traversal protocol, implemented as an HTTPS-based relay. - -**How it works**: -1. Clients attempt direct WireGuard connection via STUN/ICE. -2. If direct connection fails, both clients connect to the DERP relay via HTTPS. -3. Traffic is encrypted end-to-end with WireGuard, DERP only relays packets. -4. No additional ports needed β€” DERP uses the same HTTPS ingress as Headscale (443). - -**Performance**: DERP adds latency (extra hop through Sofia K8s cluster), but ensures connectivity in all scenarios. - -### Split DNS Architecture - -**Design goal**: Prevent tunnel dependency for public DNS resolution. If the Headscale tunnel or Cloudflared tunnel fails, clients must still resolve public domains. - -**Implementation**: -- **AdGuard DNS**: Global recursive resolver, serves all VPN clients. Includes ad-blocking and malicious domain filtering. -- **Technitium DNS**: Internal authoritative server for `.viktorbarzin.lan` domains. - -**Resolution flow**: -1. Client queries AdGuard for any domain. -2. If domain ends in `.lan`, AdGuard forwards to Technitium (10.0.20.201). -3. For all other domains, AdGuard resolves directly via upstream (Cloudflare 1.1.1.1). -4. AdGuard caches responses, reducing load on Technitium and upstream. - -**Resilience**: Even if the tunnel to Sofia is down, clients can still resolve `google.com`, `github.com`, etc., because AdGuard talks directly to Cloudflare. Only `.lan` domains become unavailable. - -### Access Control (Authentik Groups) - -**Headscale Users** group in Authentik controls VPN access. Membership is invitation-only: -1. Admin creates user in Authentik. -2. Admin adds user to "Headscale Users" group. -3. User logs in via OIDC during `tailscale login`. -4. Headscale verifies group membership via OIDC claims. - -Removing a user from the group revokes VPN access on next re-authentication (every 30 days). - -## Configuration - -### Terraform Stacks - -| Stack | Path | Resources | -|-------|------|-----------| -| Headscale | `stacks/headscale/` | Deployment, Service, Ingress, ConfigMap | -| AdGuard | `stacks/adguard/` | Deployment, Service, PVC | -| Technitium | `stacks/technitium/` | Deployment, Service, PVC | -| pfSense (Sofia) | Not in Terraform | WireGuard tunnel configs (managed via pfSense UI) | - -### Headscale Configuration - -**ConfigMap**: `stacks/headscale/main.tf` -```yaml -server_url: https://headscale.viktorbarzin.me -listen_addr: 0.0.0.0:8080 -metrics_listen_addr: 0.0.0.0:9090 - -oidc: - issuer: https://authentik.viktorbarzin.me/application/o/headscale/ - client_id: <redacted> - client_secret: <from Vault> - scope: ["openid", "profile", "email", "groups"] - allowed_groups: ["Headscale Users"] - -derp: - server: - enabled: true - region_id: 999 - region_code: "home" - region_name: "Home DERP" - stun_listen_addr: "0.0.0.0:3478" - urls: - - https://controlplane.tailscale.com/derpmap/default - auto_update_enabled: true - update_frequency: 24h - -ip_prefixes: - - 100.64.0.0/10 - -dns_config: - nameservers: - - 10.0.20.102 # AdGuard DNS - domains: - - viktorbarzin.lan - magic_dns: true -``` - -**Secrets (Vault)**: -- `secret/headscale/oidc_client_secret` - -**Ingress**: Standard `ingress_factory` with `protected = false` (OIDC is handled by Headscale itself). - -### AdGuard Configuration - -**Upstream DNS servers**: -- Cloudflare: `1.1.1.1`, `1.0.0.1` -- Google: `8.8.8.8`, `8.8.4.4` - -**Conditional forwarding**: -- `viktorbarzin.lan` β†’ `10.0.20.201` (Technitium) - -**Ad-blocking lists**: -- AdGuard DNS filter -- OISD full list -- Developer Dan's ads and tracking list - -**Custom rules**: Block telemetry for Windows, macOS, and smart TVs. - -### WireGuard (pfSense β€” Hub) - -**Single interface `tun_wg0`** (OPT2) with two peers on subnet `10.3.2.0/24`.

Users can browse the internet even if the homelab is completely offline. - -### Why Embedded DERP Relay? - -**Alternatives considered**: -1. **External DERP relays only (Tailscale's public relays)**: Free, but adds latency and exposes traffic metadata to Tailscale. -2. **No DERP, direct connections only**: Fails for symmetric NAT clients (mobile networks). - -**Decision**: Embedded DERP (region 999) provides: -- **Privacy**: All relay traffic stays within the homelab. -- **Reliability**: Not dependent on Tailscale's public infrastructure. -- **No extra ports**: DERP uses HTTPS (443), same as Headscale API. - -**Trade-off**: Adds CPU/memory overhead to Headscale pod, but minimal compared to benefits. - -### Why OIDC Authentication Instead of Pre-Authorized Keys? - -**Alternatives considered**: -1. **Pre-authorized keys**: Headscale generates keys, admin shares with users. -2. **Shared secret**: Single password for all users. - -**Decision**: OIDC via Authentik provides: -- **Centralized access control**: Add/remove users in one place. -- **Audit trail**: Authentik logs all login attempts. -- **Group-based authorization**: Only "Headscale Users" group can access VPN. -- **SSO integration**: Users already have accounts in Authentik for other services. - -**Key workflow**: Admin invites user β†’ user logs in via Authentik β†’ admin approves device β†’ access granted.

Ensure client's system time is accurate. -2. **Callback URL mismatch**: Authentik application must have `https://headscale.viktorbarzin.me/oidc/callback` in Redirect URIs. -3. **Group membership**: User is not in "Headscale Users" group in Authentik. - -**Fix**: Sync system clock, verify Authentik application config, add user to group. - -### Direct Connection Fails, Traffic Goes via DERP - -**Symptoms**: `tailscale status` shows `relay "home"` instead of direct connection. Higher latency. - -**Diagnosis**: Check DERP usage: `tailscale netcheck` - -**Common causes**: -1. **Symmetric NAT**: Mobile networks or restrictive corporate firewalls block UDP hole-punching. -2. **Firewall blocking WireGuard**: Port 51820 UDP blocked on one or both clients. -3. **STUN failure**: Can't determine external IP and port. - -**Fix**: This is expected behavior in many environments. DERP relay ensures connectivity. If latency is unacceptable, use site-to-site WireGuard instead. - -### Can't Resolve .lan Domains from VPN - -**Symptoms**: `nslookup nextcloud.viktorbarzin.lan` returns `NXDOMAIN`. - -**Diagnosis**: Check DNS chain: Client β†’ AdGuard β†’ Technitium. - -**Steps**: -1. Verify AdGuard is running: `kubectl get pod -n adguard` -2. Check AdGuard conditional forwarding: Query AdGuard directly: `nslookup nextcloud.viktorbarzin.lan <adguard-ip>` -3. Check Technitium: `nslookup nextcloud.viktorbarzin.lan 10.0.20.201` - -**Common causes**: -1. **AdGuard not forwarding .lan**: Conditional forwarding rule missing or misconfigured. -2. **Technitium down**: Pod crash-looping or PVC corrupted. -3. **DNS propagation delay**: Technitium zone update not yet applied. - -**Fix**: Verify conditional forwarding in AdGuard UI. Restart Technitium if needed. Check zone file in Technitium UI. - -### VPN Client Can't Reach K8s Services - -**Symptoms**: Can `ping 10.0.20.1` (pfSense), but `curl https://immich.viktorbarzin.me` times out. - -**Diagnosis**: Check connectivity at each layer: -1. **DNS**: Does `nslookup immich.viktorbarzin.me` return correct IP? -2. **Routing**: Can client reach MetalLB IP? `ping <loadbalancer-ip>` -3. **Firewall**: Is pfSense blocking traffic from VPN subnet? - -**Common causes**: -1. **Split DNS working too well**: Client resolves to Cloudflare IP instead of internal LAN IP. Expected for proxied domains β€” use direct domain (e.g., `immich-direct.viktorbarzin.me`). -2. **ACL policy**: Headscale ACL blocks client from accessing certain subnets. -3. **pfSense NAT rule missing**: Traffic from VPN subnet not routed to VLAN 20. - -**Fix**: For proxied domains, use non-proxied DNS names. Check Headscale ACL policy. Verify pfSense NAT rules. - -### DERP Relay Returns 502 Bad Gateway - -**Symptoms**: Tailscale clients can't connect, DERP shows offline in `tailscale netcheck`. - -**Diagnosis**: Check Headscale ingress: `kubectl get ingress -n headscale` - -**Common causes**: -1. **Traefik middleware blocking DERP traffic**: Forward-auth interferes with WebSocket upgrade. -2. **Headscale pod not ready**: Liveness probe failing. -3. **Cloudflared tunnel issue**: DERP uses WebSockets, which require HTTP/1.1 upgrade support. - -**Fix**: Ensure Headscale ingress has `protected = false` (no forward-auth). Check Headscale pod readiness. Verify Cloudflared supports WebSocket upgrades. - -### WireGuard Site-to-Site Tunnel Disconnects - -**Symptoms**: Can't reach services in London from Sofia. `ping 192.168.8.1` fails. - -**Diagnosis**: Check pfSense WireGuard status via `pfsense.py wireguard` or Dashboard β†’ VPN β†’ WireGuard β†’ Status - -**Common causes**: -1. **AllowedIPs parse error on GL-iNet**: If `wg show wgclient1` shows no peers and interface is DOWN with `qdisc noop`, check `/etc/config/wireguard` peer config. AllowedIPs must be a single comma-separated entry, not multiple `list` entries (see London section above). -2. **IPv6 endpoint resolution**: If IPv4 is down, DNS resolves to IPv6 (AAAA record). Ensure the pfSense `HE_IPv6` (gif0) interface has a `pass in` rule for UDP 51821. -3. **Keepalive packets dropped**: Firewall or ISP blocking UDP 51821. -4. **Public IP changed**: Dynamic IP on remote site changed, config still has old IP. -5. **GL-iNet policy routing lost**: After firewall reload, check if `TUNNEL10_ROUTE_POLICY` and `LOCAL_POLICY` mangle rules exist.

Changing the backend (different NFS server, different protocol) requires editing 56 stacks. - -## Constraints - -- Zero data migration β€” same NFS paths, same TrueNAS server, same directories -- Services must keep working during migration (no downtime per service beyond a pod restart) -- Must work with existing Terragrunt architecture (per-stack state isolation) -- Must not break services that will later move to local disk (per storage-reliability design) - -## Design - -### Architecture - -``` -BEFORE: - Pod spec β†’ inline nfs {} block β†’ kubelet mount -t nfs (hard,timeo=600) β†’ TrueNAS - (no health check, hangs on stale mount, server IP in every stack) - -AFTER: - Terraform module β†’ PV (CSI driver ref) + PVC β†’ Pod spec references PVC - CSI driver mounts with soft,timeo=30,retrans=3 β†’ TrueNAS - (health-checked, fails fast on stale mount, server IP in module only) -``` - -### Component 1: NFS CSI Driver (Helm chart in platform stack) - -Deploy `csi-driver-nfs` v4.11+ via Helm in `stacks/platform/modules/nfs-csi/`. - -The driver runs as: -- **Controller**: 1 replica (handles PV provisioning) -- **Node DaemonSet**: 1 per node (handles mount/unmount operations) - -Resource footprint: ~50MB RAM per node, ~10m CPU idle. - -The driver itself does not change NFS behavior β€” it delegates to the kernel NFS client. The value is: -- Mount options are configurable per-StorageClass (not hardcoded kernel defaults) -- CSI health checking can detect unhealthy volumes -- Standard K8s storage API (PV/PVC/StorageClass) instead of inline volumes - -### Component 2: StorageClass - -```hcl -resource "kubernetes_storage_class" "nfs_truenas" { - metadata { name = "nfs-truenas" } - provisioner = "nfs.csi.k8s.io" - reclaim_policy = "Retain" - volume_binding_mode = "Immediate" - - mount_options = [ - "soft", # Return -EIO instead of hanging forever - "timeo=30", # 3-second timeout per NFS RPC call - "retrans=3", # Retry 3 times before giving up (~9 sec total) - "actimeo=5", # 5-second attribute cache (balance freshness vs perf) - ] - - parameters = { - server = var.nfs_server - share = "/mnt/main" - } -} -``` - -Key mount option differences vs current defaults: - -| Option | Current (inline) | New (CSI) | Effect | -|--------|-----------------|-----------|--------| -| `hard` vs `soft` | `hard` (default) | `soft` | I/O errors instead of infinite hang | -| `timeo` | 600 (60 sec) | 30 (3 sec) | Faster failure detection | -| `retrans` | 3 | 3 | Same retry count, but 3s per attempt not 60s | -| `actimeo` | 3600 (1 hour, varies) | 5 (5 sec) | Fresher attribute cache | -| Total stale detection | **~3 minutes** | **~9 seconds** | 20x faster | - -### Component 3: Shared Terraform Module (`modules/kubernetes/nfs_volume/`) - -Creates a PV + PVC pair for each NFS mount point. Hides boilerplate. - -**Interface**: -```hcl -module "nfs_data" { - source = "../../modules/kubernetes/nfs_volume" - name = "myservice-data" # PV and PVC name (must be unique cluster-wide) - namespace = "myservice" # PVC namespace - nfs_server = var.nfs_server # From terraform.tfvars - nfs_path = "/mnt/main/myservice" # NFS export path - # Optional: - # storage = "10Gi" # Default: 10Gi (informational for NFS) - # access_modes = ["ReadWriteMany"] # Default: RWX -} -``` - -**Outputs**: -- `claim_name` β€” PVC name to reference in pod spec - -**Module creates**: -1. `kubernetes_persistent_volume` β€” CSI-backed, references StorageClass mount options -2. `kubernetes_persistent_volume_claim` β€” bound to the PV, namespaced - -PVs are cluster-scoped, so `name` must be globally unique. Convention: `-` (e.g., `openclaw-tools`, `privatebin-data`). - -### Component 4: Stack Migration (Mechanical Change) - -Each stack changes from: -```hcl -# OLD: inline NFS -volume { - name = "data" - nfs { - server = var.nfs_server - path = "/mnt/main/myservice" - } -} -``` - -To: -```hcl -# NEW: module call (outside pod spec) -module "nfs_data" { - source = "../../modules/kubernetes/nfs_volume" - name = "myservice-data" - namespace = "myservice" - nfs_server = var.nfs_server - nfs_path = "/mnt/main/myservice" -} - -# NEW: PVC reference (in pod spec, replaces nfs {} block) -volume { - name = "data" - persistent_volume_claim { - claim_name = module.nfs_data.claim_name - } -} -``` - -Volume mount blocks (`volume_mount {}`) are **completely unchanged**. - -### Component 5: Platform Module Migration - -Platform modules (redis, dbaas, monitoring, etc.) that use NFS follow the same pattern but the module path is `../../../modules/kubernetes/nfs_volume` (one extra level deep). The `nfs_server` variable is already passed through `stacks/platform/main.tf`. - -Some platform modules use explicit PV/PVC already (Loki, Prometheus). These get updated to use the CSI driver backend instead of the native NFS PV source. - -### What Does NOT Change - -- NFS export paths on TrueNAS (no `nfs_directories.txt` changes) -- NFS server configuration -- Volume mount paths inside containers -- Sub-path usage patterns -- Container images or application config -- Services that will move to local disk later (per storage-reliability design) β€” they get CSI mounts as an interim improvement, then move off NFS entirely - -## Migration Order - -Services grouped by risk. Each batch: apply β†’ verify pods running β†’ verify app accessible β†’ next batch. - -### Phase 0: Infrastructure -1. Deploy NFS CSI driver Helm chart (platform module) -2. Create `nfs-truenas` StorageClass -3. Create `modules/kubernetes/nfs_volume/` shared module - -### Phase 1: Low-Risk Pilot (3 services) -Pick 3 simple, single-volume services to validate the pattern: -- `privatebin` (1 volume, low traffic) -- `echo` β€” actually stateless, skip. Use `resume` instead (1 volume, personal site) -- `speedtest` (1 volume, low traffic) - -### Phase 2: Simple Services (single NFS volume each, ~20 services) -Mechanical migration of all single-volume stacks. Can be parallelized. - -### Phase 3: Multi-Volume Services (~15 services) -Services with 2-4 NFS volumes (openclaw, servarr, immich, etc.). More module calls but same pattern. - -### Phase 4: Platform Modules (~9 modules) -Monitoring stack, Redis, dbaas PVs, etc. These live in `stacks/platform/modules/` and need the module path adjusted. - -### Phase 5: Cleanup -- Update CLAUDE.md documentation (new NFS volume pattern) -- Update `setup-project` skill to use module pattern for new services -- Verify all services healthy - -## Rollback - -Per-service rollback: revert the stack to inline `nfs {}` and `terragrunt apply`. The data never moved β€” it's the same NFS path. PV/PVC objects get destroyed by Terraform, pod remounts inline. Takes 1 minute per service. - -Full rollback: remove CSI driver and StorageClass from platform stack, revert all stacks. No data impact. - -## Risks - -1. **`soft` mount I/O errors**: Apps that don't handle I/O errors gracefully may crash instead of hanging. This is strictly better β€” a crash triggers a restart with a fresh mount, vs hanging forever. But some apps may log noisy errors during brief NFS blips. - -2. **PV naming conflicts**: PV names are cluster-global. Must ensure uniqueness. Convention `-` handles this. - -3. **Terraform state churn**: Each service gains 2 new resources (PV + PVC) and loses the inline volume (implicit, not tracked). The `terragrunt apply` will show resource additions but no deletions (inline volumes aren't separate TF resources). Pod will be recreated. - -4. **CSI driver resource overhead**: ~50MB RAM + 10m CPU per node (5 nodes = ~250MB cluster-wide). Acceptable. - -## Success Criteria - -- [ ] NFS CSI driver deployed and healthy on all 5 nodes -- [ ] `nfs-truenas` StorageClass created with soft mount options -- [ ] `modules/kubernetes/nfs_volume/` module created and tested -- [ ] All 56 NFS-dependent services migrated from inline to PV/PVC -- [ ] No service downtime beyond a single pod restart during migration -- [ ] Simulated NFS outage (TrueNAS NFS service pause) results in pod restart (not hang) -- [ ] Documentation and skills updated for new pattern diff --git a/docs/plans/2026-03-01-nfs-csi-migration-plan.md b/docs/plans/2026-03-01-nfs-csi-migration-plan.md deleted file mode 100644 index 57cd0614..00000000 --- a/docs/plans/2026-03-01-nfs-csi-migration-plan.md +++ /dev/null @@ -1,774 +0,0 @@ -# NFS CSI Driver Migration Implementation Plan - -> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. - -**Goal:** Replace all inline NFS volumes with CSI-backed PV/PVC using soft mount options to eliminate stale mount hangs. - -**Architecture:** Deploy the NFS CSI driver as a platform Helm module, create a shared Terraform module for PV/PVC boilerplate, then mechanically migrate all 56 NFS-dependent services from inline `nfs {}` to `persistent_volume_claim {}` referencing the shared module. - -**Tech Stack:** csi-driver-nfs (Helm), Terraform/Terragrunt, Kubernetes PV/PVC/StorageClass - -**Design doc:** `docs/plans/2026-03-01-nfs-csi-migration-design.md` - ---- - -## Task 1: Create the NFS CSI Driver Platform Module - -**Files:** -- Create: `stacks/platform/modules/nfs-csi/main.tf` -- Modify: `stacks/platform/main.tf` (add module block) - -**Step 1: Create the module directory** - -```bash -mkdir -p stacks/platform/modules/nfs-csi -``` - -**Step 2: Write the NFS CSI module** - -Create `stacks/platform/modules/nfs-csi/main.tf`: - -```hcl -variable "tier" { type = string } -variable "nfs_server" { type = string } - -resource "kubernetes_namespace" "nfs_csi" { - metadata { - name = "nfs-csi" - labels = { - tier = var.tier - } - } -} - -resource "helm_release" "nfs_csi_driver" { - namespace = kubernetes_namespace.nfs_csi.metadata[0].name - create_namespace = false - name = "csi-driver-nfs" - atomic = true - timeout = 300 - - repository = "https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/master/charts" - chart = "csi-driver-nfs" - - values = [yamlencode({ - controller = { - replicas = 1 - resources = { - requests = { cpu = "10m", memory = "32Mi" } - limits = { cpu = "100m", memory = "128Mi" } - } - } - node = { - resources = { - requests = { cpu = "10m", memory = "32Mi" } - limits = { cpu = "100m", memory = "128Mi" } - } - } - storageClass = { - create = false # We create it ourselves below for full control - } - })] -} - -resource "kubernetes_storage_class" "nfs_truenas" { - metadata { - name = "nfs-truenas" - } - storage_provisioner = "nfs.csi.k8s.io" - reclaim_policy = "Retain" - volume_binding_mode = "Immediate" - - mount_options = [ - "soft", - "timeo=30", - "retrans=3", - "actimeo=5", - ] - - parameters = { - server = var.nfs_server - share = "/mnt/main" - } -} -``` - -**Step 3: Wire the module into `stacks/platform/main.tf`** - -Add after the `cnpg` module block (around line 318): - -```hcl -module "nfs-csi" { - source = "./modules/nfs-csi" - tier = local.tiers.cluster - nfs_server = var.nfs_server -} -``` - -**Step 4: Verify with plan** - -```bash -cd stacks/platform && terragrunt plan --non-interactive 2>&1 | head -80 -``` - -Expected: Plan shows 3 new resources (`kubernetes_namespace`, `helm_release`, `kubernetes_storage_class`).

-**For existing PV/PVC resources** (monitoring stack), the change is different β€” replace the `persistent_volume_source` block: - -```hcl -# OLD (in prometheus.tf): -persistent_volume_source { - nfs { - path = "/mnt/main/prometheus" - server = var.nfs_server - } -} - -# NEW: -persistent_volume_source { - csi { - driver = "nfs.csi.k8s.io" - volume_handle = "prometheus-data" - volume_attributes = { - server = var.nfs_server - share = "/mnt/main/prometheus" - } - } -} -``` - -Also add `storage_class_name = "nfs-truenas"` to the PV spec to inherit mount options. - -**For inline NFS volumes** in platform modules, use the shared module with the longer path: - -```hcl -module "nfs_data" { - source = "../../../../modules/kubernetes/nfs_volume" - name = "technitium-data" - namespace = kubernetes_namespace.technitium.metadata[0].name - nfs_server = var.nfs_server -

-**Commit:** - -```bash -git add stacks/platform/ -git commit -m "[ci skip] platform: migrate all NFS volumes to CSI PV/PVC with soft mount" -``` - ---- - -## Task 9: Update Documentation and Skills - -**Files:** -- Modify: `.claude/CLAUDE.md` (update NFS Volume Pattern section) -- Modify: `.claude/skills/setup-project/SKILL.md` (update new service template to use module) - -**Step 1: Update CLAUDE.md NFS Volume Pattern** - -Replace the existing NFS Volume Pattern section with: - -```markdown -### NFS Volume Pattern -**Use the `nfs_volume` shared module** for all NFS volumes. This creates CSI-backed PV/PVC with soft mount options (no stale mount hangs): -\```hcl -module "nfs_data" { - source = "../../modules/kubernetes/nfs_volume" - name = "-data" # Must be globally unique - namespace = kubernetes_namespace..metadata[0].name - nfs_server = var.nfs_server - nfs_path = "/mnt/main/" -} - -# In pod spec: -volume { - name = "data" - persistent_volume_claim { - claim_name = module.nfs_data.claim_name - } -} -\``` -For platform modules, use `source = "../../../../modules/kubernetes/nfs_volume"`. - -**Legacy pattern (DO NOT use for new services):** Inline `nfs {}` blocks mount with `hard,timeo=600` defaults which hang forever on stale mounts. -``` - -**Step 2: Update setup-project skill** - -Update the new service template in `.claude/skills/setup-project/SKILL.md` to use the module pattern instead of inline NFS. - -**Step 3: Commit** - -```bash -git add .claude/ -git commit -m "[ci skip] update NFS volume documentation to use CSI-backed nfs_volume module" -``` - ---- - -## Task 10: Validation β€” Simulate NFS Outage - -**This is a manual verification step. Do NOT automate.** - -After all services are migrated, simulate an NFS blip to confirm the stale mount fix works: - -1. Pick a low-risk service (e.g., `privatebin`) -2. On TrueNAS, temporarily block NFS to the K8s network (iptables rule or pause NFS for 30 seconds) -3. Observe: pod should get I/O errors within ~9 seconds (not hang) -4. If the pod has a liveness probe that touches the filesystem, it should restart automatically -5. After NFS recovers, verify the pod re-mounts cleanly - -**Do NOT run this on production without a maintenance window.** This is a "when you're ready" validation, not part of the automated migration. diff --git a/docs/plans/2026-03-01-traefik-resilience-design.md b/docs/plans/2026-03-01-traefik-resilience-design.md deleted file mode 100644 index e1fa45f1..00000000 --- a/docs/plans/2026-03-01-traefik-resilience-design.md +++ /dev/null @@ -1,237 +0,0 @@ -# Traefik Resilience Hardening Design - -**Date**: 2026-03-01 -**Status**: Approved - -## Problem Statement - -Traefik is the single ingress point for 70+ services.

Authentik β†’ BasicAuth Fallback - -Deploy a similar nginx proxy in front of Authentik's outpost: -- Normal operation: proxies to `ak-outpost-...:9000`, returns Authentik's response (SSO) -- Authentik down: falls back to nginx `auth_basic` with htpasswd credentials from a Kubernetes secret -- Protected services remain accessible to admins via basicAuth during Authentik outages - -Update the `authentik-forward-auth` middleware to point at the nginx proxy. - -**Nginx config sketch:** -```nginx -upstream authentik { - server ak-outpost-authentik-embedded-outpost.authentik.svc.cluster.local:9000; -} -server { - listen 9000; - location /outpost.goauthentik.io/auth/traefik { - proxy_pass http://authentik; - proxy_connect_timeout 3s; - proxy_read_timeout 5s; - proxy_intercept_errors on; - error_page 502 503 504 = @fallback_auth; - } - location @fallback_auth { - auth_basic "Emergency Access"; - auth_basic_user_file /etc/nginx/htpasswd; - # Return 200 with required headers if basicAuth passes - add_header X-authentik-username $remote_user; - return 200; - } - location /healthz { - return 200 "ok"; - } -} -``` - -**htpasswd secret**: Generated from existing admin credentials, stored in a Kubernetes secret, mounted into the nginx pod. - -### 2. Pod Scheduling & Disruption Protection - -#### 2a. Traefik Topology Spread + PDB - -Add to Traefik Helm values: -```yaml -topologySpreadConstraints: - - maxSkew: 1 - topologyKey: kubernetes.io/hostname - whenUnsatisfiable: DoNotSchedule - labelSelector: - matchLabels: - app.kubernetes.io/name: traefik - -podDisruptionBudget: - enabled: true - minAvailable: 2 -``` - -#### 2b. Authentik PDB - -Add to Authentik Helm values: -```yaml -server: - pdb: - enabled: true - minAvailable: 2 -``` - -#### 2c. Poison Fountain Tier Bump - -Change Poison Fountain namespace tier from `4-aux` to `1-cluster`: -- File: `stacks/poison-fountain/main.tf` -- Change: `tier = local.tiers.aux` β†’ `tier = local.tiers.cluster` -- Effect: priority bumped from 200K to 800K, preemption enabled, LimitRange defaults change (512Mi default memory, max 4Gi) - -### 3. Timeout & Backend Protection - -#### 3a. Response Header Timeout - -Change from unlimited to 30s: -``` ---serversTransport.forwardingTimeouts.responseHeaderTimeout=30s -``` - -Prevents hung backends from holding Traefik goroutines indefinitely. - -#### 3b. ForwardAuth Proxy Timeouts - -The nginx resilience proxies use 3s connect / 5s read timeouts. If the upstream doesn't respond within 5s, the fallback activates. This is much faster than waiting for the backend to eventually time out. - -#### 3c. Retry Middleware - -Add a `retry` middleware to the default chain in ingress_factory: -```yaml -retry: - attempts: 2 - initialInterval: 100ms -``` - -Handles transient 502/503 from backends that are restarting. Only retries on network errors and 5xx. - -### 4. Monitoring & Alerting - -#### 4a. PoisonFountainDown Alert - -```yaml -- alert: PoisonFountainDown - expr: kube_deployment_status_replicas_available{namespace="poison-fountain", deployment="poison-fountain"} == 0 - for: 2m - labels: - severity: critical - annotations: - summary: "Poison Fountain is down - AI bot blocking degraded to fail-open" -``` - -#### 4b. Alert Inhibition - -When `TraefikDown` fires, suppress `PoisonFountainDown`. - -#### 4c.

Migration Plan (Phased) - -**Phase 1 β€” Setup tooling (no functional change)** -- Install `sops` and `age` locally (Docker) -- Generate age keys: Viktor + CI -- Store CI age key as Woodpecker secret (`sops_age_key`) -- Move git-crypt key from K8s ConfigMap to Secret (update RBAC for Woodpecker SA) -- Create `.sops.yaml` config file -- Add `/secrets.auto.tfvars.json` to `.gitignore` -- Create `scripts/tg` wrapper -- Backup Viktor's age private key to Vaultwarden - -**Phase 2 β€” Create SOPS file alongside existing tfvars** -- Categorize all 211 variables: secret vs. non-secret (WireGuard private keys β†’ secrets) -- Extract non-secret config into `config.tfvars` (plaintext) -- Extract secrets into `secrets.sops.json` (JSON, including complex types: maps, lists, nested objects) -- Encrypt with SOPS -- Verify round-trip: `sops -d secrets.sops.json | jq .` produces valid JSON -- Verify SSH keys: `sops -d secrets.sops.json | jq -r '.truenas_ssh_private_key' | ssh-keygen -l -f -` -- Verify complex types: `sops -d secrets.sops.json | jq '.mailserver_accounts'` returns expected map -- Add `sensitive = true` to ALL secret variable declarations across all stacks (BEFORE CI plan step is enabled) - -**Phase 3 β€” Switch terragrunt to SOPS** -- Update `terragrunt.hcl`: `config.tfvars` (required) + `secrets.auto.tfvars.json` (optional) + existence check hook -- Test: `scripts/tg apply --non-interactive` works per-stack -- Test: `scripts/tg run --all -- plan` works (no race condition) -- Test failure mode: delete `secrets.auto.tfvars.json`, verify `before_hook` fails loudly - -**Phase 4 β€” Atomic cutover** -- Step 1: `git rm terraform.tfvars` (removes file while git-crypt filter still active β€” clean deletion) -- Step 2: Remove `*.tfvars filter=git-crypt` from `.gitattributes` -- Step 3: `git commit` both changes - -**Phase 5 β€” Update CI pipelines** -- Update `.woodpecker/default.yml` with new pipeline -- Update `.woodpecker/renew-tls.yml`: change `git add .` to `git add secrets/ state/` -- Add `sops_age_key` Woodpecker secret -- Enable GitHub branch protection on master -- Test: CI pipeline applies successfully - -**Phase 6 β€” Security hardening** -- Create scoped operator RBAC role -- Remove `secrets` from `power-user` ClusterRole -- Update CLAUDE.md and AGENTS.md documentation - -**Phase 7 β€” Onboard operator** -- Add as GitHub collaborator -- Create Authentik account in "operators" group -- Walk through first PR workflow - -### 10. Rollback Plan -- **Phase 1-2**: No functional change β€” delete SOPS artifacts -- **Phase 3**: Revert `terragrunt.hcl` to load `terraform.tfvars` -- **Phase 4+**: `git show HEAD~1:terraform.tfvars > terraform.tfvars`, re-add `.gitattributes` rule. Backfill any secrets added during SOPS period. -- Git-crypt stays functional for `secrets/` and `*.tfstate` - -### 11.

Security Considerations -- **Decrypted file**: temporary, `.gitignore`d, never staged by CI, cleaned up on success AND failure -- **CI staging**: `git add stacks/ state/ .woodpecker/` β€” never `git add .` (all pipelines) -- **Age key in CI**: `SOPS_AGE_KEY` env var β†’ written to temp file β†’ `SOPS_AGE_KEY_FILE` β†’ `shred` after use -- **Age key backup**: Viktor's in Vaultwarden. CI's as Woodpecker secret -- **Branch protection**: Operators cannot modify CI pipeline, terragrunt.hcl, or .sops.yaml without review -- **RBAC**: Operator role excludes cluster-wide secrets. Namespace `edit` role allows secrets within assigned namespaces (accepted residual risk). Excluded: woodpecker, kube-system, dbaas, monitoring, authentik -- **Terraform variables**: `sensitive = true` on all secret vars β€” applied in Phase 2 BEFORE plan step is enabled -- **Plan output**: filtered through `grep -v sensitive` as belt-and-suspenders -- **`local-exec` exfiltration**: residual risk mitigated by PR review requirement β€” Viktor must review all PRs -- **State files**: contain secret values, git-crypt encrypted. Future: remote backend -- **Rotation**: new CI age key β†’ re-encrypt β†’ update Woodpecker secret β†’ rotate affected secrets -- **Git history**: old `terraform.tfvars` remains git-crypt encrypted in history β€” recoverable only with git-crypt key (K8s Secret, not accessible to operators) diff --git a/docs/plans/2026-03-28-storage-migration-truenas-elimination.md b/docs/plans/2026-03-28-storage-migration-truenas-elimination.md deleted file mode 100644 index 004656f0..00000000 --- a/docs/plans/2026-03-28-storage-migration-truenas-elimination.md +++ /dev/null @@ -1,882 +0,0 @@ -# Storage Migration: TrueNAS Elimination via Proxmox CSI + Host NFS - -**Date**: 2026-03-28 -**Status**: Reviewed (3 rounds, all CRITICAL/IMPORTANT issues resolved) -**Goal**: Eliminate TrueNAS VM entirely, replacing it with Proxmox CSI (block storage for databases) and NFS served directly from the Proxmox host (for app data and backups).

Verify with: - ```bash - echo "test_metric 1" | curl --data-binary @- http://:9091/metrics/job/test - ``` - -6. **Check ZFS corruption scope** (identify affected files before migration): - ```bash - ssh root@10.0.10.15 'zpool status -v main | tail -30' - ``` - If critical data is in the error list, restore from Synology BEFORE proceeding. - -#### 0.1: Create VG and LV on sda (Host NFS) - -```bash -pvcreate /dev/sda -vgcreate sas /dev/sda -# Use nearly full capacity β€” sda is 1.1 TiB, reserve ~50G for VG metadata/overhead -lvcreate -L 1050G -n nfs-data sas -mkfs.ext4 -L nfs-data /dev/sas/nfs-data -mkdir -p /srv/nfs -echo '/dev/sas/nfs-data /srv/nfs ext4 defaults 0 2' >> /etc/fstab -mount /srv/nfs -``` - -**Capacity pre-validation** (MUST run before Phase 1): -```bash -# Check uncompressed data sizes on TrueNAS for largest consumers -ssh root@10.0.10.15 'zfs list -o name,used,refer,compressratio -r main | sort -k2 -h | tail -20' -``` -If total uncompressed NFS data exceeds 1 TiB, keep Immich (~800 GiB, largest consumer) on a separate thin LV in the `pve` VG: -```bash -# Only if needed: create Immich-specific thin LV on HDD (auto-grows in thin pool) -lvcreate -V 1T --thinpool data -n immich-data pve -mkfs.ext4 /dev/pve/immich-data -mkdir /srv/nfs-immich -echo '/dev/pve/immich-data /srv/nfs-immich ext4 defaults 0 2' >> /etc/fstab -mount /srv/nfs-immich -# Add to /etc/exports: /srv/nfs-immich 10.0.20.0/24(rw,sync,no_subtree_check,no_root_squash) -``` - -#### 0.2: Create LVM-thin Pool on sdb (SSD Tier) - -VG "ssd" already exists on sdb. Create a thin pool in the free space: - -```bash -# Verify free space in VG -vgdisplay ssd | grep Free - -# Create thin pool with explicit metadata sizing (1% of data = 6G, allows thousands of snapshots) -lvcreate -L 600G --poolmetadatasize 6G --thinpool ssd-data ssd -``` - -Note: After TrueNAS shutdown frees the 256G disk in Phase 4, expand with `lvextend -L +200G /dev/ssd/ssd-data`. - -#### 0.3: Register Proxmox Storage IDs - -The Proxmox CSI plugin requires **Proxmox storage IDs** (configured in Datacenter β†’ Storage), not raw LVM names.

Deploy `proxmox-csi-plugin` Helm chart via new Terraform stack `stacks/proxmox-csi/` - - Provisioner name: `csi.proxmox.sinextra.dev` - - Configure cluster connection (Proxmox API URL, token) - -3. Create StorageClasses (see Appendix B for full YAML): - - `proxmox-ssd`: storage ID `ssd-csi`, `ssd: "true"`, `cache: none` - - `proxmox-hdd`: storage ID `local-lvm`, `ssd: "false"`, `cache: writethrough` - -4. Create VolumeSnapshotClass for LVM-thin snapshots - -5. **Test on EVERY node** β€” create a test PVC, write data, read back, delete: - ```bash - for i in 1 2 3 4; do - # Create PVC with nodeAffinity to k8s-node$i, verify SCSI hotplug works - kubectl apply -f test-pvc-node$i.yaml - # Verify: kubectl get pvc, kubectl describe pv - # Clean up - kubectl delete -f test-pvc-node$i.yaml - done - ``` - Also test on k8s-master. If SCSI hotplug fails on any node, investigate before proceeding. - -6. **Test VolumeSnapshot**: Create a snapshot of the test PVC, restore to new PVC, verify data integrity. This validates the backup path BEFORE any production migration. - -#### 0.6: Configure NFS for K8s - -The existing NFS CSI driver (`nfs.csi.k8s.io`) supports multiple StorageClasses. Create a new StorageClass `nfs-host` pointing at the Proxmox host: - -```yaml -apiVersion: storage.k8s.io/v1 -kind: StorageClass -metadata: - name: nfs-host -provisioner: nfs.csi.k8s.io -parameters: - server: 10.0.10.1 # Proxmox host on mgmt VLAN - share: /srv/nfs -mountOptions: - - soft - - timeo=30 - - retrans=3 - - actimeo=5 -reclaimPolicy: Retain -volumeBindingMode: Immediate -``` - -Keep the old `nfs-truenas` StorageClass active during migration. Services are migrated one at a time by updating their PV/PVC to use the new server. - -Note: For services using the `nfs_volume` Terraform module (static PV/PVC), the migration involves changing the `nfs_server` parameter in the module call, not switching StorageClasses.

Update Terraform: Change `nfs_server` in `nfs_volume` module call to `10.0.10.1` and `nfs_path` from `/mnt/main/` to `/srv/nfs/` -6. `terragrunt apply` β€” updates PV to point at host NFS -7. Scale deployment to 1 -8. Verify service is healthy (check logs, Uptime Kuma, service-specific smoke test) -9. Mark old TrueNAS directory as migrated (don't delete yet) - -**Stacks requiring re-apply**: All stacks with `module.nfs_volume` calls.

Scale Immich to 0 -3. **Pass 2** (delta only): `rsync -av --checksum --delete root@10.0.10.15:/mnt/main/immich/ /srv/nfs/immich/` β€” syncs only changes since Pass 1 (1-5 min) -4. Update Terraform, apply, scale to 1 -5. Verify: upload a test photo, check ML classification, browse thumbnails - -**Disabled services** (whisper, audiblez, grampsweb, tandoor, etc.): Update Terraform to point at new NFS but don't rsync data (no data to migrate while disabled). rsync when re-enabled. - -### Phase 2: Migrate Databases to Proxmox CSI SSD - -**Duration**: 1 weekend -**Downtime per service**: 5-15 minutes -**Rollback**: CNPG switchover back to old primary; MySQL/Redis restore from dump - -This is the highest-value migration β€” databases get local SSD instead of NFS-over-ZFS-over-LVM-thin. - -**Migration Order** (dependency-aware): - -| Day | Databases | Rationale | -|-----|-----------|-----------| -| Day 1 | 2a: CNPG PostgreSQL, 2b: MySQL, 2e: Vaultwarden | Independent of each other β€” can run in parallel | -| Day 2 | 2d: Redis | Authentik depends on both PG + Redis. Migrate Redis only AFTER verifying CNPG migration is stable | -| Day 3 | 2c: Vault | All services (ESO, Authentik, backup CronJobs) depend on Vault. Migrate LAST after all other DBs are verified stable | - -**Terraform state handling**: Changing `storageClass` on PVCs requires recreation (immutable field). For each database migration: -1. The old PVCs will become orphaned (reclaimPolicy: Retain keeps the PV) -2. After verifying the new database is stable (24h), manually clean up: - ```bash - # Delete orphaned PVCs - kubectl delete pvc -n - # Delete orphaned PVs (verify they're in "Released" state first) - kubectl get pv | grep Released - kubectl delete pv - ``` -3. Old TrueNAS iSCSI zvols will be cleaned up in Phase 4 - -#### 2a: CNPG PostgreSQL - -Use dump/restore approach (safer than cross-storage streaming replication, which can fail when the underlying filesystem changes): - -1. Take fresh `pg_dumpall` from existing cluster (Layer 2 backup, plus an extra manual dump) -2. Verify the CNPG operand image includes all required extensions (pgvector, pgvecto-rs, etc.) β€” the current cluster uses `viktorbarzin/postgres:16-master` custom image. Build a compatible CNPG image or verify extensions are available. -3. Create new CNPG Cluster resource with `storageClass: proxmox-ssd` (fresh init) -4. Restore dump to new cluster: `cat dump.sql | kubectl exec -i -- psql -U postgres` -5. Update `postgresql_host` in `config.tfvars` to new cluster service (e.g., `pg-cluster-rw.dbaas.svc.cluster.local` β€” keep same name if possible to minimize changes) -6. `terragrunt apply` across all consuming stacks (12+ stacks β€” use `grep -rl postgresql_host stacks/` to enumerate) -7. Verify all services connect successfully: - - Authentik: login via web UI - - Woodpecker: trigger a test pipeline - - Immich: upload a test photo - - Grafana: load a dashboard - - All others: check pod logs for DB connection errors -8. Decommission old CNPG cluster after 24h of verified operation - -#### 2b: MySQL InnoDB Cluster - -1. Take a fresh mysqldump of all databases (Layer 2 backup) -2. Create new MySQL InnoDB Cluster Helm release with `storageClass: proxmox-ssd` -3. Restore dump to new cluster -4. Update `mysql_host` in `config.tfvars` -5. `terragrunt apply` across consuming stacks -6. Verify all MySQL-backed services (speedtest, wrongmove, grafana, etc.) -7. Decommission old MySQL cluster - -#### 2c: Vault Raft - -**Pre-migration coordination** (before scaling Vault to 0): -1. Verify no Woodpecker pipelines are queued/running -2. Scale Woodpecker to 0 to prevent deploys during window -3. Verify no backup CronJobs are currently running: `kubectl get jobs -A | grep -v Completed` -4. Do NOT run `terragrunt apply` on any stack during the 10-15 min window - -**WARNING**: Do NOT seal Vault during migration. Sealing breaks ESO (43+ ExternalSecrets), Authentik, and all backup CronJobs that read Vault. Instead, use a graceful shutdown + data copy approach. - -1. Take Vault raft snapshot (Layer 2 backup + manual snapshot for safety) -2. Scale Vault StatefulSet to 0 (graceful shutdown β€” pods terminate cleanly, no seal needed) -3. Note: During this window (~10-15 min), ESO cannot refresh secrets. Existing K8s Secrets remain valid but won't be rotated. No pod restarts should be triggered. **Do NOT run `terragrunt apply` on any stack during this window.** -4. Create new Vault Helm release with `storageClass: proxmox-ssd` -5. Copy raft data from old PVCs to new PVCs (use a temporary pod or `kubectl cp` from the backup) -6. Start new Vault StatefulSet -7. Unseal all replicas, verify cluster health: `vault status`, `vault operator raft list-peers` -8. Verify all secrets accessible: `vault kv get secret/viktor` -9. Verify ESO connectivity: `kubectl get clustersecretstore vault-kv -o jsonpath='{.status.conditions}'` -10. Decommission old Vault StatefulSet PVCs after 24h verification - -#### 2d: Redis - -1. Trigger BGSAVE on current Redis -2. Scale Redis to 0 -3. Create new Redis Helm release with `storageClass: proxmox-ssd` -4. Copy RDB dump to new PV -5. Start new Redis, verify data -6. Update `redis_host` in `config.tfvars` if changed -7. Decommission old Redis PVCs - -#### 2e: Vaultwarden - -1. Run sqlite3 `.backup` (Layer 2 backup) -2. Scale Vaultwarden to 0 -3. Create new PVC with `storageClass: proxmox-ssd` -4. Copy SQLite database to new PV -5. Update Vaultwarden deployment to use new PVC -6. Scale to 1, verify via web UI + Bitwarden client sync -7. Verify backup CronJob still works with new PVC mount - -### Phase 3: Migrate Large Stateful Workloads to Proxmox CSI HDD - -**Duration**: 1 evening -**Downtime per service**: 10-30 minutes (Prometheus has large TSDB) - -#### 3a: Prometheus - -1. Create new PVC with `storageClass: proxmox-hdd`, size 200Gi -2. Scale Prometheus to 0 -3. rsync TSDB data from old iSCSI PV to new block PV (may take 20-30 min for ~27GB) -4. Update Prometheus Helm values to use new StorageClass -5. Start Prometheus, verify metrics continuity -6. Decommission old iSCSI PVC - -#### 3b: Ollama - -1. Create new PVC with `storageClass: proxmox-hdd` -2. Scale Ollama to 0 -3. rsync models from old NFS to new block PV -4. Update deployment -5. Verify model loading -6. Decommission old NFS volume - -### Phase 4: TrueNAS Shutdown and Cleanup - -**Duration**: 1 evening -**Prerequisites**: All services migrated and verified for at least 1 week with no issues - -1. **Final verification**: - - All services healthy (Uptime Kuma green) - - All backup CronJobs running (Grafana dashboard green) - - Offsite sync to Synology running (check Pushgateway metrics) - - No pods mounting TrueNAS NFS or iSCSI - -2. **Shutdown TrueNAS VM**: - ```bash - qm shutdown 9000 - ``` - -3. **Monitor for 1 week** (matches success criteria): Watch for any services that silently depended on TrueNAS. Check Uptime Kuma, Grafana backup dashboard, and Prometheus alerts daily. - -4. **Reclaim resources** (only after 1-week verification β€” once LVs are removed, TrueNAS rollback is impossible): - - Remove TrueNAS VM definition from Terraform - - Remove the 7 thin LVs (scsi1-scsi7) that were TrueNAS ZFS vdevs β€” frees ~1.7 TiB in thin pool: - ```bash - # List TrueNAS LVs - lvs pve | grep 'vm-9000' - # Remove each one - lvremove -f /dev/pve/vm-9000-disk-1 - # ... repeat for disk-2 through disk-7 - ``` - - Remove TrueNAS SSD disk (vm-9000-disk-0 on sdb) β€” frees 256 GiB on SSD VG: - ```bash - lvremove -f /dev/ssd/vm-9000-disk-0 - ``` - - Expand SSD thin pool with reclaimed space (safe to do online with active thin volumes). Extend both data and metadata proportionally: - ```bash - lvextend -L +200G /dev/ssd/ssd-data - lvextend --poolmetadatasize +2G /dev/ssd/ssd-data # Keep metadata at ~1% of data - lvs ssd/ssd-data # Verify new size - ``` - -5. **Remove old CSI drivers**: - - Remove `democratic-csi` (iSCSI) Helm release and Terraform stack - - Remove old `nfs-truenas` StorageClass (keep `nfs-host`) - - Remove TrueNAS SSH key from Vault - - Remove TrueNAS API credentials from Vault - -6. **Update documentation**: - - Update `infra/docs/architecture/storage.md` - - Update `infra/docs/architecture/backup-dr.md` - - Update `infra/.claude/CLAUDE.md` storage sections - - Update `AGENTS.md` if storage references exist - -7. **Synology backup path**: Keep the existing path `truenas` on Synology β€” renaming would cause rclone to re-upload everything. The path name is cosmetic; the content is what matters. Add a note file at the root: `echo "Source: PVE host /srv/nfs (migrated from TrueNAS $(date))" > /srv/nfs/.source-info` - -### Phase 5: Post-Migration Hardening - -1. **LVM snapshot monitoring**: Verify Prometheus scrapes LVM snapshot metrics, Grafana panels show snapshot age and count -2. **Offsite sync monitoring**: Verify Prometheus alerts for OffsiteSyncStale/Failing -3. **Disaster recovery test**: Restore a database from backup to verify the full backupβ†’restore path works end-to-end -4. **Capacity alerting**: Add alerts for: - - SSD thin pool >80% full - - HDD thin pool >80% full - - NFS thick LV >85% full -5. **Update memory/CLAUDE.md**: Store the new architecture mapping -6. **Proxmox CSI VolumeSnapshot test**: Create a VolumeSnapshot of a database PV, restore it to a new PVC, verify data integrity - -## Rollback Plan - -Each phase is independently rollbackable: - -| Phase | Rollback Procedure | Data Loss Risk | -|-------|-------------------|----------------| -| Phase 0 | Remove Proxmox CSI, NFS server, crons. No service impact | None | -| Phase 1 | Switch PV back to TrueNAS NFS path. rsync delta back | None (TrueNAS still has original data) | -| Phase 2 | CNPG switchover back; MySQL restore from dump; Vault restore from raft snapshot | Minimal (since last dump) | -| Phase 3 | Re-create iSCSI PVC, rsync back | None | -| Phase 4 | Boot TrueNAS VM, re-attach LVs (only possible before LV reclaim in step 4 β€” 1-week window) | N/A (only done after full verification) | - -## Risk Register - -| Risk | Likelihood | Impact | Mitigation | -|------|-----------|--------|------------| -| Proxmox CSI plugin bug / incompatibility | Medium | High | Test extensively in Phase 0; keep TrueNAS alive until Phase 4 | -| SCSI hotplug fails on specific VM | Low | Medium | Test on each node in Phase 0; fallback to NFS for that node | -| NFS kernel server performance worse than TrueNAS | Low | Low | TrueNAS was double-CoW; host NFS on SAS 10K disk should be faster | -| Proxmox API token permissions insufficient | Low | Low | Test all CSI operations in Phase 0 before any migration | -| rclone offsite sync misses files without zfs diff | Low | Medium | Use rsync (checksums all files); accept slightly longer runtime | -| LVM thin pool fills during migration | Low | High | Monitor pool usage during Phase 1-3; current usage is 37% | -| Service depends on TrueNAS in unexpected way | Low | Medium | 48-hour monitoring period in Phase 4 before decommission | -| Proxmox host reboot disrupts NFS + block PVs simultaneously | Medium | High | This is same as current (TrueNAS VM is on same host). No regression. Schedule reboots during maintenance windows | -| CNPG custom image missing extensions after migration | Low | High | Verify extensions (pgvector, pgvecto-rs) in CNPG image before migration; build custom image if needed | -| NFS ports blocked by pfSense between VLANs | Medium | High | Test NFS connectivity from K8s nodes to PVE host in Phase 0.0 pre-flight | -| Corrupted ZFS data migrated to new storage | Low | High | Check `zpool status -v` before migration; restore corrupted files from Synology backup first | - -## Success Criteria - -- [ ] All services healthy on new storage for 1+ week -- [ ] All backup CronJobs green on Grafana dashboard -- [ ] Offsite sync to Synology running with metrics -- [ ] LVM snapshot cron running with metrics -- [ ] TrueNAS VM shut down and resources reclaimed -- [ ] No double-CoW β€” single LVM-thin CoW layer only -- [ ] 16 vCPU + 16 GB RAM freed for K8s workloads -- [ ] SCSI budget: ≀5 devices per node average, no single node exceeding 10 -- [ ] DR test: successfully restore at least 1 database from backup on new infrastructure - -## Appendix A: Proxmox Host NFS vs TrueNAS NFS - -| Property | TrueNAS NFS | Host NFS | -|----------|-------------|----------| -| CoW layers | 2 (ZFS + LVM-thin) | 0 (thick LV, ext4) | -| Checksumming | ZFS (but can't repair β€” RAID0) | None (ext4) | -| Compression | lz4 (1.26Γ—) | None | -| Network hop | VM NIC β†’ bridge β†’ physical | Direct on host | -| RAM overhead | 16 GB (ZFS ARC) | ~0 (kernel NFS is lightweight) | -| Management UI | TrueNAS WebUI | /etc/exports (text file) | -| Snapshot quality | ZFS (excellent but corrupted) | LVM thick β€” no snapshots (use backups) | -| Effective capacity | ~1.26Γ— via lz4 compression (~800G for 1 TiB logical) | 1:1 (no compression). Allocate 1 TiB for ~1 TiB of data. Monitor usage; current NFS data is 1.39 TiB but largest consumers (Immich) may compress well on ZFS but not on ext4 | - -**Note on capacity**: Losing ZFS lz4 compression (1.26Γ—) means effective capacity drops. Current NFS data is 1.39 TiB compressed. Uncompressed, this could be ~1.75 TiB. The 1 TiB thick LV on sda may not be sufficient for all data. **Mitigation**: Monitor during Phase 1 migration. If approaching 85%, either (a) extend the LV (sda has 1.1 TiB total, 100G is reserved for VG metadata), or (b) keep large datasets (Immich ~800G) on a separate LV on sdc's thin pool. - -## Appendix A.1: Superseded Plans - -This plan **supersedes** the pending "iSCSI PV pin & rename migration" plan (`~/.claude/plans/ticklish-singing-donut.md`). That plan proposed renaming iSCSI PVs on TrueNAS β€” since TrueNAS is being eliminated entirely, the rename migration is no longer needed. All iSCSI PVs will be replaced with Proxmox CSI block PVs in Phase 2-3. - -## Appendix B: Proxmox CSI StorageClass Definitions - -**Important**: The `storage` parameter must reference a **Proxmox storage ID** (as configured in Datacenter β†’ Storage in the Proxmox UI), NOT the raw LVM thin pool name. The SSD storage must be registered in Phase 0.3 before these StorageClasses will work. - -```yaml -# proxmox-ssd StorageClass -apiVersion: storage.k8s.io/v1 -kind: StorageClass -metadata: - name: proxmox-ssd -provisioner: csi.proxmox.sinextra.dev -parameters: - storage: ssd-csi # Proxmox storage ID (registered in Phase 0.3, points to ssd/ssd-data thin pool) - ssd: "true" - cache: none # Required for databases β€” ensures fsync reaches disk -reclaimPolicy: Retain -volumeBindingMode: WaitForFirstConsumer -allowVolumeExpansion: true - ---- -# proxmox-hdd StorageClass -apiVersion: storage.k8s.io/v1 -kind: StorageClass -metadata: - name: proxmox-hdd -provisioner: csi.proxmox.sinextra.dev -parameters: - storage: local-lvm # Proxmox storage ID (already exists, points to pve/data thin pool) - ssd: "false" - cache: writethrough # Balance performance and safety for TSDB/model workloads -reclaimPolicy: Retain -volumeBindingMode: WaitForFirstConsumer -allowVolumeExpansion: true -``` - -Note: `volumeBindingMode: WaitForFirstConsumer` ensures PVs are created on the same node as the pod, preventing cross-node scheduling issues. Combined with anti-affinity rules on database StatefulSets, this spreads block PVs across nodes and avoids SCSI budget concentration. - -## Appendix C: SCSI Device Distribution - -Proxmox CSI hotplugs SCSI devices into VMs. Each VM supports up to 30 SCSI devices (scsi0-scsi29). With boot disk using scsi0, 29 slots remain per node. - -Current plan uses ~14 block PVs total across 5 nodes: -- Databases (CNPG Γ—3, MySQL Γ—3, Redis Γ—2, Vault Γ—3, Vaultwarden Γ—1) = 12 -- Large workloads (Prometheus Γ—1, Ollama Γ—1) = 2 -- Total: 14 PVs across 5 nodes = ~3 per node average - -Remaining capacity: 14 PVs using ~3 SCSI slots per node leaves ~26 free slots per node. Even if scheduler imbalance puts 8-10 on one node, that's still well under the 29-slot limit. Anti-affinity rules on database StatefulSets ensure spread. - -## Appendix D: Data Sizes for Migration Planning - -| Service | Current Size (approx) | Migration Method | Expected Duration | -|---------|-----------------------|------------------|-------------------| -| Immich | ~800 GiB (photos/video) | rsync NFSβ†’NFS | 30-60 min | -| servarr/downloads | ~200 GiB | rsync NFSβ†’NFS | 15-30 min | -| ytdlp | ~50 GiB | rsync NFSβ†’NFS | 5-10 min | -| Prometheus TSDB | ~27 GiB | rsync iSCSIβ†’block | 5-10 min | -| CNPG PostgreSQL | ~10 GiB | pg_dumpall / restore | 10-15 min | -| MySQL InnoDB | ~5 GiB | mysqldump/restore | 5 min | -| All other NFS services | <5 GiB each | rsync NFSβ†’NFS | <2 min each | diff --git a/docs/plans/2026-04-03-proxmox-csi-cleanup-todo.md b/docs/plans/2026-04-03-proxmox-csi-cleanup-todo.md deleted file mode 100644 index e25113c8..00000000 --- a/docs/plans/2026-04-03-proxmox-csi-cleanup-todo.md +++ /dev/null @@ -1,88 +0,0 @@ -# Proxmox CSI Migration β€” Cleanup TODO - -**Date**: 2026-04-03 -**Status**: Pending (do when confident everything is stable) -**Prerequisites**: All services healthy on proxmox-lvm for 1+ week - -## Context - -The iSCSI β†’ Proxmox CSI migration is complete.

Each headline is a 1-line hook; deep-dives below. - -1. **Declarative escape hatches (NFS exports, master-node file provisioners, null_resource initializers)** β€” `/etc/exports` is not in Terraform, which is the **root cause of the 2026-04-14 SEV1**; 6 null_resources + 3 SSH file provisioners still orchestrate critical state. *Hits R2 + R1 + R3.* -2. **Observability has blind spots where pain would actually come from** β€” no OOMKill alert routing, no NFS capacity monitor, no GPU utilization dashboard, no ESO refresh-lag alert, no CronJob success-rate summary. Alerts exist but they don't cover the operator's real failure modes. *Hits R1 + R3 + R4.* -3. **Supply-chain hygiene: image pinning + Renovate + admission signing** β€” 84 `:latest` tags in production TF, zero Renovate/Dependabot across 18 repos (~15 hr/mo toil by estimate), no cosign/trivy on push. Single theme unifies security posture, maintenance toil, and determinism. *Hits R3 + R5.* -4. **Reliability-probes & graceful shutdown are genuinely uneven** β€” 115 deployments missing at least one probe (incl. 103 missing both), 50+ Recreate deployments with no `terminationGracePeriodSeconds`/`preStop`. This is the quietly-largest reliability debt. *Hits R1 + R3 (pager toil).* -5. **Backup coverage is uneven: 30+ PVCs lack app-level CronJobs** β€” Proxmox host snapshots cover the disk, but Forgejo (!), Affine, Paperless, Hackmd, Matrix, Owntracks have no app-aware dumps. Restore granularity is file-level, not entity-level. *Hits R1 + R5 (compliance) + R3 (restore rehearsal toil).* - -Honourable mentions that didn't make top 5 but sit just below: Kyverno auditβ†’enforce transition (security), ESO refresh-lag alert (secrets reliability), Vault hardening (audit log offsite, root-token K8s-secret scope), Cloudflared tunnel-token SPOF (not replica SPOF β€” those are 3), Dolt PVC sizing + backup. - ---- - -## Scoring method - -Two parallel rankings β€” scan both. - -**Rank A β€” Impact Γ— Reversibility (the original formula)** -`score = Impact Γ— (6 - Effort) Γ— (6 - Risk)` β€” each dimension 1-5. - -**Rank B β€” Operator fatigue weight** -`score = Impact Γ— (6 - Effort) Γ— FatigueWeight` where `FatigueWeight = 3` if the finding introduces *daily/weekly manual toil* and `1` otherwise. This re-ranks by how much pain the unfixed state causes per month. - -Both rankings below. When they agree, that's the clear signal. When they diverge, that's where Rank B (fatigue) wins β€” Viktor has stated operator fatigue dominates abstract risk for a solo-operator lab. - ---- - -## Ranked backlog (filtered, deduplicated, corrected) - -Counts below reflect **post-challenge corrected numbers**.

What actually matters: - -- **Probes (F02)** β€” 115 deployments missing at least one probe; 103 missing both. The corrected count is 2.4Γ— the original claim. Worst offenders are batch workloads (CronJob-spawned) that legitimately skip probes β€” but long-lived ones (Affine, Hackmd, mailserver sidecars) genuinely need them. Triage: filter by `spec.replicas β‰₯ 1` and `containers[].command != ["/bin/sh","-c"]`-style short-runners, then add readiness+liveness one-by-one. -- **Cloudflared tunnel token SPOF (F10)** β€” Replicas are 3 (per CLAUDE.md), so the agent finding "SPOF" framed as replicas is wrong. The real SPOF is the *tunnel credential*. Secondary tunnel with weighted Cloudflare DNS records is the honest fix β€” medium effort, low urgency unless tunnel CA rolls keys. -- **PDB gaps (F13-like, excluded from table)** β€” After challenger correction, gaps are: CrowdSec LAPI (3 replicas, no PDB), ESO webhook+controller, Woodpecker-server. Not urgent β€” drain-test with `kubectl drain --dry-run` shows no current issue. -- **App-level backups (F09)** β€” Proxmox host captures the PVC contents nightly via LVM snapshot + rsync with `--link-dest` weekly versioning, so file-level recovery is covered. But for databases inside PVCs (e.g. Affine's Postgres in-pod, Paperless' SQLite), app-aware dumps give transactional consistency. Audit pass: enumerate every PVC without a sibling `*-backup` CronJob, add one for the ones that host embedded DBs. -- **MySQL restore drill (F11)** β€” Migrated 4 days ago. Runbook exists. End-to-end restore (dump β†’ new DB β†’ connect an app β†’ verify) hasn't been rehearsed. SEV1 risk if a dump has been silently broken since migration. -- **Vault update strategy (F17)** β€” `OnDelete` means helm upgrade leaves pods untouched; must manually `kubectl delete pod` to restart. Low impact (infrequent) but procedural toil. -- **Dolt PVC near-full + no backup (F16)** β€” `bd list --status in_progress` runs against this DB; it's load-bearing for cross-session task state. Grow the PVC (resize annotation) + add dolt dump CronJob. - -### R2 β€” Declarative Coverage & Drift (16 raw β†’ 8 real) - -Filtered: dropped R2#1 (Kyverno markers are by-design), corrected R2#3 to 310. - -- **NFS exports (F01)** β€” The file is git-managed at `infra/scripts/pve-nfs-exports` but deployed via `scp + exportfs -ra`, not Terraform. This is the exact path that caused the 2026-04-14 SEV1 (fsid=0 on wrong exports line). Options: (a) `null_resource` with `local-exec scp + remote-exec exportfs -ra` triggered on hash of content (partial β€” SSH dep); (b) new module `pve_host_config` that templates and SCPs multiple PVE-host artifacts with checksum verification. (b) is the cleaner long-term fix. -- **Null-resource initializers (F06)** β€” 6 in `dbaas` (MySQL users, CNPG cluster, TF-state role, payslip DB, job-hunter DB). Some are genuinely unavoidable (bootstrapping DB before the DB exists); others could use `postgresql_grant` / `mysql_user` providers. -- **SSH file provisioners on k8s-master (F07)** β€” `apiserver-oidc.tf`, `audit-policy.tf`, `etcd tuning`. One-way sync, no drift detection. Proposed quick wins (per `2026-02-22-node-drift-quick-wins-design.md` already exists). Continue/finish the plan. -- **CoreDNS scaling manual (F24)** β€” Current runbook uses `kubectl scale`/`set env`/`set affinity`. Drift-prone; convert to `kubernetes_deployment` TF resource overriding the Helm chart's scale/affinity fields. -- **MySQL InnoDB Cluster + operator TF resources still present** β€” Phase 4 cleanup. Low urgency, but removing reduces cognitive load on anyone reading `stacks/dbaas/`. -- **Technitium readiness-gate null_resource with `timestamp()` trigger** β€” Runs every apply, 3-6 min wall time. Replace with a real health-check on `terraform_data` with `triggers_replace = { checksum = sha256(config) }`. -- **GPU node taints + Proxmox CSI labels via null_resource kubectl** β€” No drift detection. Fix is in the `2026-02-22-node-drift-quick-wins-design.md` plan. - -### R3 β€” Maintenance overhead (18 raw β†’ 10 real) - -- **Renovate (F03)** β€” The single highest-leverage maintenance fix. 18 repos Γ— ~0.8 hrs/month manual version sweep = real time. Add `.github/renovate.json` (grouping rules for Terraform providers, K8s provider, Docker images) + auto-merge patch-level. Start with `infra/` only; expand after 2 weeks. -- **Image pinning (F04)** β€” 84 `:latest` tags in production TF. Root CLAUDE.md still says "use 8-char git SHA tags" but that's not enforced. Admission control via Kyverno `require-trusted-registries` is in Audit today β€” add a sibling policy `forbid-latest-tag` also in Audit. Separate from F03 because pin-to-SHA + Renovate is a synergistic pair. -- **MySQL restore drill (F11)** β€” tracked under R1 for impact; also a maintenance item because the restore *procedure* has not been test-updated since migration. -- **CronJob alert rollup (F14)** β€” 59 CronJobs; "which were healthy last 24h" takes ad-hoc `kubectl get jobs --sort-by` scrolling. Add a Grafana panel with `kube_cronjob_status_last_successful_time < now - 2Γ—schedule` summary. -- **Graceful-shutdown toil (F23)** β€” 50+ Recreate deployments without `terminationGracePeriodSeconds` or `preStop`. Noisy pager hits after node drain. One-off sweep: add a 30s `terminationGracePeriodSeconds` default via Kyverno mutation rule. -- **Tier-0 SOPS workflow (F30)** β€” 7-step decrypt/edit/encrypt/commit vs Tier-1's 3-step. Combined `tg` wrapper flag `--edit ` that auto-decrypts β†’ EDITOR β†’ auto-encrypts β†’ commit in one command. Moderate win; low risk. -- **Stale `in_progress` beads** β€” 7 stale tasks in `bd list --status in_progress` at audit start. Session-end hook checks this; 3-5 days without notes is the signal. CLAUDE.md covers the rule β€” it's followed-sometimes, not enforced. -- **Runbook staleness** β€” no `last_reviewed` frontmatter on runbook MDs; trivial to add. One-off sweep then keep it honest. -- **CI/CD template unification** β€” "GHA build β†’ Woodpecker deploy" is the documented pattern for 10 repos; rest still on Woodpecker-only. Track as follow-ups per repo in `bd`. -- **Kyverno DNS-config boilerplate 307 markers** β€” Not a problem (see correction at top). Do add a lint rule in CI that flags any `kubernetes_deployment` without `# KYVERNO_LIFECYCLE_V1` marker; that's the real drift risk. - -### R4 β€” Scalability (18 raw β†’ 9 real) - -Filtered: dropped R4#1 (metric mispull), R4#2 (CPU-limit policy), R4#7 (Phase 7 solved). - -- **CNPG memory headroom** β€” Currently 2Gi limit. Top-line metric at quiet time; add a `ContainerNearOOM > 85%` rule that watches CNPG specifically (general rule exists; CNPG is Tier 0 so deserves explicit binding). -- **HPA cluster-wide: zero** β€” Every stateless service is 1:1. Not urgent at current node-CPU 8-31%, but one big feature (Immich re-index, Authentik load spike) tips the balance. Pilot: HPA on Traefik (CPU-driven), observe, expand. -- **Redis no HPA + HAProxy singleton** β€” Wire Sentinel into direct client access (Phase 8 of Redis refactor, per R1#11 of raw findings). Currently all 17 consumers go via HAProxy β€” the single-point bypass was deliberate (simpler client config), but the HAProxy is now the SPOF Sentinel was meant to prevent. Worth a plan doc (`plans/2026-MM-DD-redis-phase8-sentinel-clients.md`). -- **PgBouncer pool sizing unknown** β€” Authentik has 3 pods, each opening N connections. At load spikes (big org sync), pool exhaustion. Short-term: `pgbouncer_show_pools` metric + alert at 80% util. Longer-term: pool-size tuning based on observed wait times. -- **Prometheus TSDB (F26)** β€” 200Gi retention unquantified. Risk: disk fills β†’ scrape gaps β†’ audit blind. Add `kubelet_volume_stats_used_bytes{persistentvolumeclaim="prometheus-server"} > 0.85 * capacity` alert. -- **NFS capacity not monitored** β€” PVE host has 1TB HDD LV. No `node_filesystem_avail_bytes` scrape from PVE host (it's outside the cluster). Install node_exporter on PVE host; scrape via Prometheus federation or remote_write. -- **VPA quarterly review unscheduled** β€” Goldilocks is in `Initial` mode (not Auto, by design). Review is manual per quarter. Calendar event + runbook link. -- **Registry single instance** β€” Registry outage = no pod restarts. Post-mortem 2026-04-19 documented a container-engine pin; replica count still 1. Consider HA registry backed by S3-compat store (MinIO in-cluster) for the second replica β€” but low urgency given probe CJ monitors integrity every 15m. -- **No ResourceQuota utilization alert** β€” Quota exhaustion invisible until a pod refuses to schedule. `kube_resourcequota{type="used"} / kube_resourcequota{type="hard"} > 0.85` rule. - -### R5 β€” Security & Secrets (21 raw β†’ 13 real) - -- **Vault `vault-unseal-key` K8s Secret (F21-related)** β€” Challenger A said it wasn't present; it is (`kubectl get secret -n vault`). Used by auto-unseal. RBAC on the secret should restrict to `vault-server` SA only. Audit the `role` + `rolebinding` in `stacks/vault/`. -- **Vault audit log offsite (F21)** β€” Rotated logs not synced to NFS backup. Add a `vault-audit-log-sync` CronJob or append the audit log path to `nfs-change-tracker` inotify list (zero-Terraform change if the latter). -- **Kyverno audit β†’ enforce (F12) β€” sequence carefully** β€” All 16 policies are in Audit today. Naive switch to Enforce will block legitimate workloads (Loki, Frigate, nvidia-device-plugin, wireguard have privileged/host-ns requirements β€” all documented). Plan: (a) generate `Kyverno PolicyException` CRs for known-good workloads first; (b) enforce one policy at a time, 1-week observation; (c) start with `require-trusted-registries` (least breakage risk). **DANGEROUS TO EXECUTE NAIVELY β€” don't batch.** -- **No NetworkPolicies (F18)** β€” Challenger correctly flagged the effort (5) and risk (4): wrong NetworkPolicy stops Authentik from reaching its DB in minutes. Approach: allow-list namespace-wide first (e.g. `authentik` ns can reach `dbaas` on 5432), expand over a month. Single biggest latent security improvement but needs runway. -- **RBAC oidc-power-user secrets r/w cluster-wide (F19)** β€” Scope down: list which Authentik groups get this binding, remove `secrets:*` from the cluster role, add namespace-scoped RoleBindings where needed. Medium effort, high leverage. -- **Image supply chain (F20)** β€” cosign verification + admission controller is the mature path. Trivy-on-push fits in GHA workflows. Both unblocked after F04 (pinning). -- **`:latest` tags (overlap F04)** β€” Security aspect: signed-image admission requires stable refs. -- **Privileged containers** β€” Loki, WireGuard, NVIDIA, Frigate known-exceptions. Document the exceptions inline (comment block on the TF resource) so future maintainers don't accidentally "fix" them. -- **Git history plaintext secrets** β€” Challenger B flagged unverified. One way to verify cheaply: `git secrets --scan-history`. Add it as a pre-audit one-off. -- **CrowdSec Metabase disabled, no Prometheus exporter** β€” R5#18. Enable the Prometheus exporter (no Metabase) for attack-pattern visibility; very cheap. -- **cert-manager evaluation paused** β€” Documented pause; TLS rotation relies on Cloudflare wildcard. Confirm no local `Ingress` uses a self-managed cert that could expire silently. `kubectl get cert -A` β†’ expect 0. -- **Pod Security Standards (F27)** β€” Label every namespace `pod-security.kubernetes.io/enforce=restricted` (or baseline). Known-exception namespaces get explicit downgrades. Medium effort, paid back by making future admission decisions uniform. -- **CrowdSec LAPI quorum** β€” 3 replicas but quorum/consensus behavior undocumented. One-page runbook: what happens if 1, 2, or 3 LAPI pods die. -- **Authentik outpost fix (F15)** β€” Applied via API, not TF. Next Helm upgrade reverts. Add the `/dev/shm` emptyDir to `stacks/authentik/values.yaml` templatefile. - ---- - -## Dangerous-to-execute (handle with care) - -Flagged by challengers; each needs a gradual rollout plan, not a single commit. - -1. **F12 β€” Kyverno Audit β†’ Enforce en masse**. Write `PolicyException` CRs for known-safe workloads first. One policy per week. Observe. -2. **F18 β€” NetworkPolicies cluster-wide**. Default-deny breaks inter-namespace lookups silently. Namespace-by-namespace rollout, with `kubectl logs -f` tailing the policy-engine events. -3. **PDB additions without drain-test**. New PDB + tight `minAvailable` can deadlock during node cordons. `kubectl drain --dry-run` every new PDB on every node first. -4. **F20 β€” Signed-image admission**. Must follow F04 (pinning). Un-pinned admission = half the cluster fails to pull. - -## Gaps the agents missed - -From challenger "GAPS" analyses, collated: - -- **Disaster-recovery drill coverage** β€” backup docs are comprehensive (CLAUDE.md is extensive). End-to-end *restore* rehearsal frequency = never documented. Track per-component: MySQL, PostgreSQL/CNPG, Vault, etcd, NFS, registry blobs. -- **Service mesh evaluation** β€” Never formally evaluated (Istio, Linkerd, Cilium-in-mesh-mode). Could subsume NetworkPolicy effort + mTLS + observability. Worth a design doc even if answer is "no, too much complexity for the gain." -- **Chaos engineering coverage** β€” Zero.
