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.
- Replace subPath ConfigMap mount with init container that copies openclaw.json
to writable NFS home (OpenClaw writes back to the file at runtime)
- Remove invalid memory-api plugin references causing "Config invalid"
- Increase memory to 2Gi (req+limit) with NODE_OPTIONS=--max-old-space-size=1536
- Fix tg wrapper to inject -auto-approve when apply --non-interactive is used
Part of SOPS multi-user secrets migration.
- .sops.yaml: defines age recipients (Viktor + CI)
- scripts/tg: wrapper that decrypts secrets before running terragrunt
- .gitignore: excludes decrypted secrets.auto.tfvars.json
No functional change — terraform.tfvars still works as before.
