8b43692af0 [infra] Suppress Goldilocks vpa-update-mode label drift on all namespaces [ci skip]
## 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.

Closes: code-dwx

e80b2f026f [infra] Migrate Terraform state from local SOPS to PostgreSQL backend
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)

06a0d0599a regenerate providers.tf: remove vault_root_token variable [ci skip] 2026-03-15 21:21:01 +00:00

3aba29e7a3 remove SOPS pipeline, deploy ESO + Vault DB/K8s engines
Vault is now the sole source of truth for secrets. SOPS pipeline
removed entirely — auth via `vault login -method=oidc`.

Part A: SOPS removal
- vault/main.tf: delete 990 lines (93 vars + 43 KV write resources),
  add self-read data source for OIDC creds from secret/vault
- terragrunt.hcl: remove SOPS var loading, vault_root_token, check_secrets hook
- scripts/tg: remove SOPS decryption, keep -auto-approve logic
- .woodpecker/default.yml: replace SOPS with Vault K8s auth via curl
- Delete secrets.sops.json, .sops.yaml

Part B: External Secrets Operator
- New stack stacks/external-secrets/ with Helm chart + 2 ClusterSecretStores
  (vault-kv for KV v2, vault-database for DB engine)

Part C: Database secrets engine (in vault/main.tf)
- MySQL + PostgreSQL connections with static role rotation (24h)
- 6 MySQL roles (speedtest, wrongmove, codimd, nextcloud, shlink, grafana)
- 6 PostgreSQL roles (trading, health, linkwarden, affine, woodpecker, claude_memory)

Part D: Kubernetes secrets engine (in vault/main.tf)
- RBAC for Vault SA to manage K8s tokens
- Roles: dashboard-admin, ci-deployer, openclaw, local-admin
- New scripts/vault-kubeconfig helper for dynamic kubeconfig

K8s auth method with scoped policies for CI, ESO, OpenClaw, Woodpecker sync.
