## Why The sonarr/radarr/prowlarr deployments gated app startup on their Postgres database being reachable using a hand-written `psql`-in-a-shell loop running the `postgres:17-alpine` image. Now that `unkin/waitfordb` is released (v0.1.0), replace that inline probe with the purpose-built tool so the wait logic lives in one tested place instead of being copy-pasted per workload. `waitfordb` reads the same `PG*` env as a libpq fallback and exits `0` once `SELECT 1` succeeds under those credentials/database, so the retrofit is a drop-in — the password still never lands in argv. ## Changes - Swap the `wait-for-db` initContainer image from `dockerhub/library/postgres:17-alpine` to `docker-internal/waitfordb:v0.1.0` (pinned, not `latest`) in all three arrstack deployments. - Drop the `sh -c` psql loop `command` — `waitfordb` is the image entrypoint. - Keep the existing `PGHOST/PGPORT/PGDATABASE/PGUSER/PGPASSWORD` env, the `wait-for-db` name, and the resource requests/limits unchanged. - Add `WAITFORDB_TIMEOUT=5m` so a stuck database fails the pod fast, and `WAITFORDB_SSLMODE=disable` to match the in-cluster Postgres. Validated with `kubectl kustomize apps/overlays/au-syd1/arrstack` (builds clean; 3 waitfordb refs, no remaining postgres init image).
