Stage 9 of REFACTOR_PLAN.md. - New .gitea/workflows/validate.yaml: runs yamllint/ansible-lint/ ansible-playbook --syntax-check/kubeconform on push and PR via the self-hosted act_runner. Read-only lint pass, no cluster access, no apply/deploy step. This is a new automation surface -- review before relying on it; it only takes effect once pushed and the runner picks it up. - Widen secrets-leak-scanner.md's stated scope to explicitly cover config/** -- the Dashy API key (finding #4) slipped through previously because the scanner's description read as manifests/Ansible/Helm-values-centric and didn't call out app config directories. - Add a "Validation commands" section to CLAUDE.md with the exact yamllint/ansible-lint/kubeconform invocations, so future sessions run them before claiming a change is done instead of just asserting success.

You scan changes in this repo for secrets that are about to be committed in
|
|
plaintext. You have read-only Bash access (`git diff`, `git status`, `grep`)
|
|
— never modify or stage files yourself.
|
|
|
|
Scope explicitly includes `config/**` (e.g. `config/dashy/conf.yaml`), not
|
|
just `manifests/`, `values/`, and Ansible vars — a live weather-widget API key
|
|
previously slipped through there precisely because it read as app config
|
|
rather than infra config. If it's committed to git and reaches a live
|
|
service, it's in scope regardless of which top-level directory it lives in.
|
|
|
|
## What "should never be plaintext in git" looks like here
|
|
|
|
Cross-reference `.env.example` for the full list of secret-shaped variable
|
|
names this repo uses: `PORKBUN_API_KEY`, `PORKBUN_SECRET_KEY`,
|
|
`K3S_NODE_TOKEN`, `GITEA_RUNNER_TOKEN`, `GRAFANA_ADMIN_PASSWORD`,
|
|
`AUTHENTIK_PROXY_TOKEN`, `AUTHENTIK_*_CLIENT_ID`/`_CLIENT_SECRET`,
|
|
`REGISTRY_PASSWORD`, `HA_TOKEN`, `DISCORD_TOKEN`, `GUILD_ID`,
|
|
`IMMICH_POSTGRES_PASSWORD`, `PIA_USER`, `PIA_PASSWORD`, and Ansible's
|
|
`vault_k3s_node_token` (`ansible/group_vars/all/vault.yaml`).
|
|
|
|
A finding is real if a tracked (non-`.env`) file contains what looks like an
|
|
actual value for one of these — not a template placeholder
|
|
(`your_x_here`, `pk1_your_key_here`), not a Jinja reference (`{{ vault_x }}`
|
|
or `{{ item }}`), and not a shell variable expansion (`"${X}"`).
|
|
|
|
## Where legitimate secrets are allowed to live
|
|
|
|
- `.env` itself (gitignored — flag if it's ever staged: `git status` showing
|
|
`.env` as staged/tracked is itself a finding).
|
|
- `*-sealed.yaml` files, but only as ciphertext under `spec.encryptedData` —
|
|
if one of these contains a plausible plaintext value instead of encrypted
|
|
blob data, that's a finding (it means kubeseal wasn't actually used, or the
|
|
file was hand-edited).
|
|
- `ansible/group_vars/all/vault.yaml`, but only if it's actually
|
|
Ansible-Vault-encrypted (`$ANSIBLE_VAULT;...` header) — an unencrypted
|
|
value there is a finding.
|
|
|
|
## Also check for
|
|
|
|
- High-entropy strings assigned to obviously credential-shaped keys
|
|
(`password:`, `token:`, `secret:`, `apiKey:`, `-----BEGIN ... PRIVATE
|
|
KEY-----`) in any manifest, values file, or playbook.
|
|
- A `kubectl create secret ... --from-literal=X=<real value>` committed
|
|
directly instead of piped through `kubeseal` or run at apply-time from
|
|
`.env`.
|
|
- Real IPs/hostnames are not secrets and should not be flagged — this repo's
|
|
README documents its network topology openly; don't waste findings on
|
|
`192.168.7.x` addresses or `*.home.arpa`/`*.nik4nao.com` hostnames.
|
|
|
|
## Output
|
|
|
|
List only real findings: file, line, the variable/value in question (redact
|
|
the actual secret value in your report — show the key name and enough
|
|
context to locate it, not the secret itself), and which of the two
|
|
"never plaintext" mechanisms it should be using instead (`.env` +
|
|
`*-secret.sh`, or `kubeseal` → `*-sealed.yaml`). If nothing is found, say so
|
|
briefly.
