The Prometheus scrape config for the kubernetes-nodes job kept
capacity_bytes + used_bytes but dropped available_bytes. pvc-autoresizer
computes utilization from available/capacity, so without that metric it
was silent for every PVC in the cluster — including mailserver, which
filled to 89% (1.7G/2.0G) and started rejecting all inbound mail with
'452 4.3.1 Insufficient system storage' (15+ hours, all real senders:
Brevo, Gmail, Facebook).
Also bumps the floors of mailserver (2Gi -> 5Gi, limit 10Gi) and forgejo
(15Gi -> 30Gi) PVCs to recover from the immediate outage, and adds
ignore_changes on requests.storage so future autoresizer expansions
don't cause TF drift.
Forgejo→Woodpecker webhooks were timing out on first request after
pod restart. The default 5s deadline is too tight for the cold
Cloudflare-tunnel TLS handshake (observed 6-8s). 30s comfortably
covers retries.

The Forgejo→Woodpecker webhook (so Woodpecker fires on each push to
viktor/<repo>) was being blocked by the existing ALLOWED_HOST_LIST
of *.svc.cluster.local — ci.viktorbarzin.me resolves to the public IP
because Cloudflare proxying wasn't covering that path. Without this
fix, no Woodpecker pipeline run was triggered on push, the dual-push
bake would never start, and Forgejo's package catalog stays empty.
Add ci.viktorbarzin.me explicitly + *.viktorbarzin.me as a future-
proofing wildcard. The list still excludes arbitrary external hosts,
so this is not a security regression — just unblocking the webhook
to our own CI.

Phase 0 enabled packages but the pod crashloops on
`mkdir /data/tmp: permission denied` — Forgejo loads the chunked
upload path (default /data/tmp/package-upload) before s6-overlay
gets a chance to chown /data. fsGroup tells kubelet to recursively
chown the volume to GID 1000 on mount, which fixes it.
Pre-23-day Forgejo deployed with packages off so this code path
never ran.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Setting it to /data/tmp/package-upload triggers a CrashLoopBackOff
because /data is the volume mount root and is owned by root, not
the forgejo user (uid 1000) — Forgejo can't `mkdir /data/tmp`.
The default value resolves under the AppDataPath (a subdir Forgejo
itself owns) which works fine. Keep the ENABLED=true override; v11
ships packages on but explicit is safer.

Wrap the three new Vault key reads in try(...) so the first apply
succeeds even when forgejo_pull_token / forgejo_cleanup_token /
secret/ci/global haven't been populated yet. Without this, CI
auto-apply blocks on the very push that introduces the references —
chicken-and-egg with the runbook order (which is: apply Forgejo bumps,
then create users + PATs, then apply the rest).
Empty tokens are intentionally visible-broken (auth fails, probe
reports auth failure, cleanup CronJob errors) — that's the signal
to run the bootstrap runbook. Subsequent apply picks up the real
values.

Stage 1 of moving private images off the registry:2 container at
registry.viktorbarzin.me:5050 (which has hit distribution#3324 corruption
3x in 3 weeks) onto Forgejo's built-in OCI registry. No cutover risk —
pods still pull from the existing registry until Phase 3.
What changes:
* Forgejo deployment: memory 384Mi→1Gi, PVC 5Gi→15Gi (cap 50Gi).
Explicit FORGEJO__packages__ENABLED + CHUNKED_UPLOAD_PATH (defensive,
v11 default-on).
* ingress_factory: max_body_size variable was declared but never wired
in after the nginx→Traefik migration. Now creates a per-ingress
Buffering middleware when set; default null = no limit (preserves
existing behavior). Forgejo ingress sets max_body_size=5g to allow
multi-GB layer pushes.
* Cluster-wide registry-credentials Secret: 4th auths entry for
forgejo.viktorbarzin.me, populated from Vault secret/viktor/
forgejo_pull_token (cluster-puller PAT, read:package). Existing
Kyverno ClusterPolicy syncs cluster-wide — no policy edits.
* Containerd hosts.toml redirect: forgejo.viktorbarzin.me → in-cluster
Traefik LB 10.0.20.200 (avoids hairpin NAT for in-cluster pulls).
Cloud-init for new VMs + scripts/setup-forgejo-containerd-mirror.sh
for existing nodes.
* Forgejo retention CronJob (0 4 * * *): keeps newest 10 versions per
package + always :latest. First 7 days dry-run (DRY_RUN=true);
flip the local in cleanup.tf after log review.
* Forgejo integrity probe CronJob (*/15): same algorithm as the
existing registry-integrity-probe. Existing Prometheus alerts
(RegistryManifestIntegrityFailure et al) made instance-aware so
they cover both registries during the bake.
* Docs: design+plan in docs/plans/, setup runbook in docs/runbooks/.
Operational note — the apply order is non-trivial because the new
Vault keys (forgejo_pull_token, forgejo_cleanup_token,
secret/ci/global/forgejo_*) must exist BEFORE terragrunt apply in the
kyverno + monitoring + forgejo stacks. The setup runbook documents
the bootstrap sequence.
Phase 1 (per-project dual-push pipelines) follows in subsequent
commits. Bake clock starts when the last project goes dual-push.

## Context
Wave 3A (commit c9d221d5) added the `# KYVERNO_LIFECYCLE_V1` marker to the
27 pre-existing `ignore_changes = [...dns_config]` sites so they could be
grepped and audited. It did NOT address pod-owning resources that were
simply missing the suppression entirely. Post-Wave-3A sampling (2026-04-18)
found that navidrome, f1-stream, frigate, servarr, monitoring, crowdsec,
and many other stacks showed perpetual `dns_config` drift every plan
because their `kubernetes_deployment` / `kubernetes_stateful_set` /
`kubernetes_cron_job_v1` resources had no `lifecycle {}` block at all.
Root cause (same as Wave 3A): Kyverno's admission webhook stamps
`dns_config { option { name = "ndots"; value = "2" } }` on every pod's
`spec.template.spec.dns_config` to prevent NxDomain search-domain flooding
(see `k8s-ndots-search-domain-nxdomain-flood` skill). Without `ignore_changes`
on every Terraform-managed pod-owner, Terraform repeatedly tries to strip
the injected field.
## This change
Extends the Wave 3A convention by sweeping EVERY `kubernetes_deployment`,
`kubernetes_stateful_set`, `kubernetes_daemon_set`, `kubernetes_cron_job_v1`,
`kubernetes_job_v1` (+ their `_v1` variants) in the repo and ensuring each
carries the right `ignore_changes` path:
- **kubernetes_deployment / stateful_set / daemon_set / job_v1**:
`spec[0].template[0].spec[0].dns_config`
- **kubernetes_cron_job_v1**:
`spec[0].job_template[0].spec[0].template[0].spec[0].dns_config`
(extra `job_template[0]` nesting — the CronJob's PodTemplateSpec is
one level deeper)
Each injection / extension is tagged `# KYVERNO_LIFECYCLE_V1: Kyverno
admission webhook mutates dns_config with ndots=2` inline so the
suppression is discoverable via `rg 'KYVERNO_LIFECYCLE_V1' stacks/`.
Two insertion paths are handled by a Python pass (`/tmp/add_dns_config_ignore.py`):
1. **No existing `lifecycle {}`**: inject a brand-new block just before the
resource's closing `}`. 108 new blocks on 93 files.
2. **Existing `lifecycle {}` (usually for `DRIFT_WORKAROUND: CI owns image tag`
from Wave 4, commit a62b43d1)**: extend its `ignore_changes` list with the
dns_config path. Handles both inline (`= [x]`) and multiline
(`= [\n x,\n]`) forms; ensures the last pre-existing list item carries
a trailing comma so the extended list is valid HCL. 34 extensions.
The script skips anything already mentioning `dns_config` inside an
`ignore_changes`, so re-running is a no-op.
## Scale
- 142 total lifecycle injections/extensions
- 93 `.tf` files touched
- 108 brand-new `lifecycle {}` blocks + 34 extensions of existing ones
- Every Tier 0 and Tier 1 stack with a pod-owning resource is covered
- Together with Wave 3A's 27 pre-existing markers → **169 greppable
`KYVERNO_LIFECYCLE_V1` dns_config sites across the repo**
## What is NOT in this change
- `stacks/trading-bot/main.tf` — entirely commented-out block (`/* … */`).
Python script touched the file, reverted manually.
- `_template/main.tf.example` skeleton — kept minimal on purpose; any
future stack created from it should either inherit the Wave 3A one-line
form or add its own on first `kubernetes_deployment`.
- `terraform fmt` fixes to pre-existing alignment issues in meshcentral,
nvidia/modules/nvidia, vault — unrelated to this commit. Left for a
separate fmt-only pass.
- Non-pod resources (`kubernetes_service`, `kubernetes_secret`,
`kubernetes_manifest`, etc.) — they don't own pods so they don't get
Kyverno dns_config mutation.
## Verification
Random sample post-commit:
```
$ cd stacks/navidrome && ../../scripts/tg plan → No changes.
$ cd stacks/f1-stream && ../../scripts/tg plan → No changes.
$ cd stacks/frigate && ../../scripts/tg plan → No changes.
$ rg -c 'KYVERNO_LIFECYCLE_V1' stacks/ --include='*.tf' --include='*.tf.example' \
| awk -F: '{s+=$2} END {print s}'
169
```
## Reproduce locally
1. `git pull`
2. `rg 'KYVERNO_LIFECYCLE_V1' stacks/ | wc -l` → 169+
3. `cd stacks/navidrome && ../../scripts/tg plan` → expect 0 drift on
the deployment's dns_config field.

## Context
Wave 3B-continued: the Goldilocks VPA dashboard (stacks/vpa) runs a Kyverno
ClusterPolicy `goldilocks-vpa-auto-mode` that mutates every namespace with
`metadata.labels["goldilocks.fairwinds.com/vpa-update-mode"] = "off"`. This
is intentional — Terraform owns container resource limits, and Goldilocks
should only provide recommendations, never auto-update. The label is how
Goldilocks decides per-namespace whether to run its VPA in `off` mode.
Effect on Terraform: every `kubernetes_namespace` resource shows the label
as pending-removal (`-> null`) on every `scripts/tg plan`. Dawarich survey
2026-04-18 confirmed the drift. Cluster-side count: 88 namespaces carry the
label (`kubectl get ns -o json | jq ... | wc -l`). Every TF-managed namespace
is affected.
This commit brings the intentional admission drift under the same
`# KYVERNO_LIFECYCLE_V1` discoverability marker introduced in c9d221d5 for
the ndots dns_config pattern. The marker now stands generically for any
Kyverno admission-webhook drift suppression; the inline comment records
which specific policy stamps which specific field so future grep audits
show why each suppression exists.
## This change
107 `.tf` files touched — every stack's `resource "kubernetes_namespace"`
resource gets:
```hcl
lifecycle {
# KYVERNO_LIFECYCLE_V1: goldilocks-vpa-auto-mode ClusterPolicy stamps this label on every namespace
ignore_changes = [metadata[0].labels["goldilocks.fairwinds.com/vpa-update-mode"]]
}
```
Injection was done with a brace-depth-tracking Python pass (`/tmp/add_goldilocks_ignore.py`):
match `^resource "kubernetes_namespace" ` → track `{` / `}` until the
outermost closing brace → insert the lifecycle block before the closing
brace. The script is idempotent (skips any file that already mentions
`goldilocks.fairwinds.com/vpa-update-mode`) so re-running is safe.
Vault stack picked up 2 namespaces in the same file (k8s-users produces
one, plus a second explicit ns) — confirmed via file diff (+8 lines).
## What is NOT in this change
- `stacks/trading-bot/main.tf` — entire file is `/* … */` commented out
(paused 2026-04-06 per user decision). Reverted after the script ran.
- `stacks/_template/main.tf.example` — per-stack skeleton, intentionally
minimal. User keeps it that way. Not touched by the script (file
has no real `resource "kubernetes_namespace"` — only a placeholder
comment).
- `.terraform/` copies (e.g. `stacks/metallb/.terraform/modules/...`) —
gitignored, won't commit; the live path was edited.
- `terraform fmt` cleanup of adjacent pre-existing alignment issues in
authentik, freedify, hermes-agent, nvidia, vault, meshcentral. Reverted
to keep the commit scoped to the Goldilocks sweep. Those files will
need a separate fmt-only commit or will be cleaned up on next real
apply to that stack.
## Verification
Dawarich (one of the hundred-plus touched stacks) showed the pattern
before and after:
```
$ cd stacks/dawarich && ../../scripts/tg plan
Before:
Plan: 0 to add, 2 to change, 0 to destroy.
# kubernetes_namespace.dawarich will be updated in-place
(goldilocks.fairwinds.com/vpa-update-mode -> null)
# module.tls_secret.kubernetes_secret.tls_secret will be updated in-place
(Kyverno generate.* labels — fixed in 8d94688d)
After:
No changes. Your infrastructure matches the configuration.
```
Injection count check:
```
$ rg -c 'KYVERNO_LIFECYCLE_V1: goldilocks-vpa-auto-mode' stacks/ | awk -F: '{s+=$2} END {print s}'
108
```
## Reproduce locally
1. `git pull`
2. Pick any stack: `cd stacks/<name> && ../../scripts/tg plan`
3. Expect: no drift on the namespace's goldilocks.fairwinds.com/vpa-update-mode label.

Two-tier state architecture:
- Tier 0 (infra, platform, cnpg, vault, dbaas, external-secrets): local
state with SOPS encryption in git — unchanged, required for bootstrap.
- Tier 1 (105 app stacks): PostgreSQL backend on CNPG cluster at
10.0.20.200:5432/terraform_state with native pg_advisory_lock.
Motivation: multi-operator friction (every workstation needed SOPS + age +
git-crypt), bootstrap complexity for new operators, and headless agents/CI
needing the full encryption toolchain just to read state.
Changes:
- terragrunt.hcl: conditional backend (local vs pg) based on tier0 list
- scripts/tg: tier detection, auto-fetch PG creds from Vault for Tier 1,
skip SOPS and Vault KV locking for Tier 1 stacks
- scripts/state-sync: tier-aware encrypt/decrypt (skips Tier 1)
- scripts/migrate-state-to-pg: one-shot migration script (idempotent)
- stacks/vault/main.tf: pg-terraform-state static role + K8s auth role
for claude-agent namespace
- stacks/dbaas: terraform_state DB creation + MetalLB LoadBalancer
service on shared IP 10.0.20.200
- Deleted 107 .tfstate.enc files for migrated Tier 1 stacks
- Cleaned up per-stack tiers.tf (now generated by root terragrunt.hcl)

Terragrunt now generates cloudflare_provider.tf (Vault-sourced API key)
and includes cloudflare in required_providers. These are the generated
files from running `terragrunt init -upgrade` across all stacks.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
## Context
Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.
## This change:
- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
`*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
dns_type. 17 hostnames remain centrally managed (Helm ingresses,
special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.
```
BEFORE AFTER
config.tfvars (manual list) stacks/<svc>/main.tf
| module "ingress" {
v dns_type = "proxied"
stacks/cloudflared/ }
for_each = list |
cloudflare_record auto-creates
tunnel per-hostname cloudflare_record + annotation
```
## What is NOT in this change:
- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)

Add proxmox-lvm PVCs with pvc-autoresizer annotations for all
SQLite-backed services. Deployments updated to use new block storage
PVCs. Old NFS modules retained for 1-week rollback.
Services: ntfy, freshrss, insta2spotify, actualbudget (x3),
wealthfolio, navidrome (DB only), audiobookshelf config,
headscale, forgejo, uptime-kuma.
Also: set Recreate strategy on ntfy, forgejo, insta2spotify,
wealthfolio (required for RWO volumes).
- Terragrunt-regenerated providers.tf across stacks (vault_root_token
variable removed from root generate block)
- Upstream monitoring/openclaw/CLAUDE.md changes from rebase
SQLite backup via Online Backup API + copy of RSA keys,
attachments, sends, and config. 30-day retention with rotation.
Pod affinity ensures co-scheduling with vaultwarden for RWO PVC access.
- Set memory requests = limits across 56 stacks to prevent overcommit
- Right-sized limits based on actual pod usage (2x actual, rounded up)
- Scaled down trading-bot (replicas=0) to free memory
- Fixed OOMKilled services: forgejo, dawarich, health, meshcentral,
paperless-ngx, vault auto-unseal, rybbit, whisper, openclaw, clickhouse
- Added startup+liveness probes to calibre-web
- Bumped inotify limits on nodes 2,3 (max_user_instances 128->8192)
Post node2 OOM incident (2026-03-14). Previous kubelet config had no
kubeReserved/systemReserved set, allowing pods to starve the kernel.
- Add vault provider to root terragrunt.hcl (generated providers.tf)
- Delete stacks/vault/vault_provider.tf (now in generated providers.tf)
- Add 124 variable declarations + 43 vault_kv_secret_v2 resources to
vault/main.tf to populate Vault KV at secret/<stack-name>
- Migrate 43 consuming stacks to read secrets from Vault KV via
data "vault_kv_secret_v2" instead of SOPS var-file
- Add dependency "vault" to all migrated stacks' terragrunt.hcl
- Complex types (maps/lists) stored as JSON strings, decoded with
jsondecode() in locals blocks
Bootstrap secrets (vault_root_token, vault_authentik_client_id,
vault_authentik_client_secret) remain in SOPS permanently.
Apply order: vault stack first (populates KV), then all others.
CPU limits cause CFS throttling even when nodes have idle capacity.
Move to a request-only CPU model: keep CPU requests for scheduling
fairness but remove all CPU limits. Memory limits stay (incompressible).
Changes across 108 files:
- Kyverno LimitRange policy: remove cpu from default/max in all 6 tiers
- Kyverno ResourceQuota policy: remove limits.cpu from all 5 tiers
- Custom ResourceQuotas: remove limits.cpu from 8 namespace quotas
- Custom LimitRanges: remove cpu from default/max (nextcloud, onlyoffice)
- RBAC module: remove cpu_limits variable and quota reference
- Freedify factory: remove cpu_limit variable and limits reference
- 86 deployment files: remove cpu from all limits blocks
- 6 Helm values files: remove cpu under limits sections
Add Kubernetes ingress annotations for Homepage auto-discovery across
~88 services organized into 11 groups. Enable serviceAccount for RBAC,
configure group layouts, and add Grafana/Frigate/Speedtest widgets.
Phase 5 — CI pipelines:
- default.yml: add SOPS decrypt in prepare step, change git add . to
specific paths (stacks/ state/ .woodpecker/), cleanup on success+failure
- renew-tls.yml: change git add . to git add secrets/ state/
Phase 6 — sensitive=true:
- Add sensitive = true to 256 variable declarations across 149 stack files
- Prevents secret values from appearing in terraform plan output
- Does NOT modify shared modules (ingress_factory, nfs_volume) to avoid
breaking module interface contracts
Note: CI pipeline SOPS decryption requires sops_age_key Woodpecker secret
to be created before the pipeline will work with SOPS. Until then, the old
terraform.tfvars path continues to function.
Remove the module "xxx" { source = "./module" } indirection layer
from all 66 service stacks. Resources are now defined directly in
each stack's main.tf instead of through a wrapper module.
- Merge module/main.tf contents into stack main.tf
- Apply variable replacements (var.tier -> local.tiers.X, renamed vars)
- Fix shared module paths (one fewer ../ at each level)
- Move extra files/dirs (factory/, chart_values, subdirs) to stack root
- Update state files to strip module.<name>. prefix
- Update CLAUDE.md to reflect flat structure
Verified: terragrunt plan shows 0 add, 0 destroy across all stacks.
Move all 88 service modules (66 individual + 22 platform) from
modules/kubernetes/<service>/ into their corresponding stack directories:
- Service stacks: stacks/<service>/module/
- Platform stack: stacks/platform/modules/<service>/
This collocates module source code with its Terragrunt definition.
Only shared utility modules remain in modules/kubernetes/:
ingress_factory, setup_tls_secret, dockerhub_secret, oauth-proxy.
All cross-references to shared modules updated to use correct
relative paths. Verified with terragrunt run --all -- plan:
0 adds, 0 destroys across all 68 stacks.
Generated individual stack directories for all 66 services under stacks/.
Each stack has terragrunt.hcl (depends on platform) and main.tf (thin
wrapper calling existing module). Migrated all 64 active service states
from root terraform.tfstate to individual state files. Root state is now
empty. Verified with terragrunt plan on multiple stacks (no changes).
