Replaces `redis.redis:6379` with `redis-master.redis:6379` in all 11
dependency.kyverno.io/wait-for annotations across 8 stacks, plus one
docs comment in the Kyverno module.
These annotations drive DNS-only `nc -z` init-container readiness
checks — zero RW risk. Both hostnames resolve, so there is no wait-for
failure window during the rolling re-apply.
Closes: code-otr
## 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
Stage 5 of ollama decommission. The `trading-bot` stack has been entirely
commented out since 2026-04-06 (deployments scaled to 0, infra disabled to
prevent re-creation on apply). The commented body still contained references
to `var.ollama_host`, `TRADING_OLLAMA_HOST`, and `TRADING_OLLAMA_MODEL`.
Removing them now so if/when the stack is ever re-enabled, those dead
references don't need remembering.
## This change
- Removes `variable "ollama_host"` from the commented-out block.
- Removes `TRADING_OLLAMA_HOST` and `TRADING_OLLAMA_MODEL` from the
commented `common_env` locals.
- Verified the outer `/* ... */` comment block still wraps the entire stack
(head: `/*`, tail: `*/`).
- No apply needed — stack is disabled.
## Test plan
### Automated
- None — file content is inside a block comment; Terraform parser ignores it.
- `terraform fmt` check: no effect (commented content).
### Manual Verification
- `head -1 stacks/trading-bot/main.tf` → `/*`
- `tail -1 stacks/trading-bot/main.tf` → `*/`

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.

## 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

```
## 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)

- NFS CSI: fix liveness-probe port conflict (29652 → 29653)
- Immich ML: add gpu-workload priority class to enable preemption on node1
- dbaas: right-size MySQL memory limits (sidecar 6Gi→350Mi, main 4Gi→3Gi)
- Redis: add redis-master service via HAProxy for master-only routing,
update config.tfvars redis_host to use it
- CoreDNS: forward .viktorbarzin.lan to Technitium ClusterIP (10.96.0.53)
instead of stale LoadBalancer IP (10.0.20.200)
- Trading bot: comment out all resources (no longer needed)
- Vault: remove trading-bot PostgreSQL database role
Kyverno ClusterPolicy reads dependency.kyverno.io/wait-for annotation
and injects busybox init containers that block until each dependency
is reachable (nc -z). Annotations added to 18 stacks (24 deployments).
Includes graceful-db-maintenance.sh script for planned DB maintenance
(scales dependents to 0, saves replica counts, restores on startup).
- 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
Use correct dashboard-icons names where available (changedetection,
gramps-web), Material Design Icons for custom apps (city-guesser,
plotting-book, resume, tuya-bridge, trading-bot, poison-fountain),
and Simple Icons for F1 Stream.
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.
- Kyverno policy: VPA mode set to 'off' for all namespaces (was 'initial'
for non-core). Terraform is now sole authority for container resources.
Goldilocks provides recommendations only.
- Ollama: add explicit CPU/memory resources (500m/4Gi req, 4/12Gi limit)
alongside GPU allocation. Fixes OOMKill from VPA scaling down resources.
- MySQL InnoDB Cluster: bump memory limit from 2Gi to 3Gi.
- Remove redundant per-namespace VPA opt-out labels from onlyoffice,
openclaw, trading-bot (now handled globally by Kyverno policy).
Major milestone - shared PostgreSQL moved from NFS to CloudNativePG:
- CNPG cluster (pg-cluster) running in dbaas namespace on local-path storage
- PostGIS image (ghcr.io/cloudnative-pg/postgis:16) for dawarich compatibility
- All 20 databases and 19 roles restored from pg_dumpall backup
- postgresql.dbaas Service patched to point at CNPG primary
- Old PG deployment scaled to 0 (NFS data intact for rollback)
- All 12+ dependent services verified running:
authentik, n8n, dawarich, tandoor, linkwarden, netbox, woodpecker,
rybbit, affine, health, resume, trading-bot, atuin
- Authentik PgBouncer working through the switched endpoint
