## Why The sonarr/radarr/prowlarr images self-generate an API key into /config/config.xml on first boot, so the key is unmanaged and differs per volume reset. This makes Vault the source of truth for those keys (override bootstrap, chosen by Ben): the key is minted in Vault and enforced into config.xml before each app starts. ## Changes - Add a `VaultAuth` `default` in the `arrstack` namespace (kubernetes auth, mount `k8s/au/syd1`, role `default`, SA `default`), mirroring jellyfin. - Add a per-app `VaultStaticSecret` that syncs `kv/kubernetes/namespace/arrstack/default/<app>` (key `apitoken`) into the `<app>-apikey` Secret. The `default` k8s role's templated policy already grants read on that path for the `arrstack/default` SA, so no terraform-vault change is needed. - Add an `apikey-init` initContainer to each of the three deployments that reads `API_KEY` from the VSO-created Secret, fails closed on a missing or non-hex value, and writes/updates only the `<ApiKey>` element in `/config/config.xml` (then fixes ownership 1000:1000, mode 600). Image is a pinned busybox via artifactapi to keep this PR atomic (no new image dependency). - Wire the new manifests into the base and per-app kustomizations. ## Notes - Keys already seeded in Vault at `kv/kubernetes/namespace/arrstack/default/<app>`. - nzbget is out of scope: it has no config.xml `<ApiKey>` (uses ControlPassword), a separate follow-up. - Downstream consumers (proxy, terraform) currently read `kv/service/media-apps/<app>`; the authoritative key now lives at the path above. Reconciliation is deferred. --------- Co-authored-by: unkin-agent <unkin-agent@git.unkin.net> Reviewed-on: #369 Co-authored-by: Unkin Agent <unkin-agent@unkin.net> Co-committed-by: Unkin Agent <unkin-agent@unkin.net>
