arrstack: run sonarr/radarr/prowlarr active-active on shared Postgres (#383)
## Why
The arrstack `sonarr`/`radarr`/`prowlarr` apps currently run as single-replica upstream LinuxServer images on SQLite (RWO config PVC, `Recreate` strategy) — no HA, no horizontal scale, and a hard one-pod ceiling because SQLite can't be shared. Our `-unkin2` forks move all app state into PostgreSQL and use Postgres advisory locks for cross-replica coordination (migrations, scheduled tasks, command execution), which makes an **active-active multi-replica** deployment safe.
This is a fresh Postgres backend — **no SQLite data migration**. The current single-replica pods are throwaway baselines; the new pods start on an empty per-app database and the fork's provider migrates the schema on first start. `arrproxy` (its own `arrproxy-db`) and `nzbget` are untouched.
## What
New `apps/base/arrstack/postgres/`:
- `cnpg_cluster.yaml` — CNPG `Cluster` `arrstack-postgres` (3 instances, `cephrbd-fast-delete`), throwaway `app` initdb owner, and 3 `managed.roles` (`sonarr`/`radarr`/`prowlarr`, login non-superuser) each with `passwordSecret: <app>-db`.
- `database-{sonarr,radarr,prowlarr}.yaml` — CNPG `Database` `<app>-main` owned by `<app>`, `databaseReclaimPolicy: retain`.
- `cnpg_backup.yaml` — cephrgw `ObjectStoreUser` + `Bucket cnpg-arrstack` + nightly `ScheduledBackup` (mirrors jellyfin).
- `vaultstaticsecret.yaml` — 3 VSO `VaultStaticSecret`s syncing `<app>-db` (keys `username`/`password`) from `kv/kubernetes/namespace/arrstack/default/<app>-db` (already seeded); these are both the CNPG role `passwordSecret` and the Deployment's Postgres creds.
- sync-waves: `<app>-db` Secrets (0) → Cluster (1) → Databases (2).
- added `postgres` to `apps/base/arrstack/kustomization.yaml`.
Per app (`sonarr`/`radarr`/`prowlarr`):
- `deployment.yaml`: image → `docker-internal/<app>:v<base>-unkin2` (sonarr `v5.0.0`, radarr `v6.4.2`, prowlarr `v2.6.2`); `replicas: 3`; `RollingUpdate`. Removed the `apikey-init` initContainer and `PUID`/`PGID`/`TZ`. Runs the binary directly (`command: [/app/<Bin>]`, `args: [-nobrowser, -data=/config, -nosingleinstancecheck]`). Env from the new ConfigMap + `secretKeyRef`: `<App>__Postgres__User`/`__Password` (Secret `<app>-db`) and `<App>__Auth__ApiKey` (existing `<app>-apikey`, key `apitoken`). `/<app>/ping` probes kept. `securityContext` runAsUser/runAsGroup/fsGroup 1000 for CephFS group-write.
- new `configmap.yaml`: non-secret `<App>__…` env (Postgres Host/Port/MainDb, `Log__DbEnabled=false`, `Auth__Method=External`, `Auth__Required=DisabledForLocalAddresses`, `App__InstanceName`, `Server__Port`, `Server__UrlBase=/<app>`, `Update__Mechanism=External`).
- `pvc-config.yaml` → RWX `cephfs-raid5-retain` (shared `/config` for `config.xml`/MediaCover).
- unchanged: `service.yaml`, `gateway.yaml`, `httproute.yaml`, apikey `vaultstaticsecret.yaml` — arrproxy still addresses the Service VIP, so N replicas are transparent.
## Validation
`kustomize build apps/overlays/au-syd1/arrstack` clean; `kubeconform` **64/64 valid**; `yamllint` and the repo pre-commit (incl. no-plain-secrets) pass. Runtime validation (pods Ready, single migrate under advisory lock, scheduled-task/command single-owner, UI via `https://arrstack.unkin.net/<app>/`, 3→1→3 rescale) is post-merge once ArgoCD syncs.
## Decisions / unknowns
- **Fork image UID/fsGroup**: the `-unkin2` images have no `USER` (run as root); pinned `runAsUser`/`runAsGroup`/`fsGroup: 1000` with `fsGroupChangePolicy: OnRootMismatch`. Verify group-write on the shared CephFS `/config` on first deploy.
- **Config storage**: chose RWX `cephfs-raid5-retain` shared `/config` (per spec preference) over per-pod `emptyDir`.
- **Postgres storage/version/resources**: mirrored jellyfin/arrproxy CNPG conventions — `cephrbd-fast-delete` 10Gi, PG17, 3 instances.

arrstack: sonarr/radarr/prowlarr/nzbget on shared CephFS media (#366)
## Why Stands up the download-automation stack (sonarr, radarr, prowlarr, nzbget) in a new `arrstack` namespace, sharing the same CephFS TV/movies subvolumes that jellyfin serves read-only (jellyfin static-PV rework is on the base branch, PR #237). Downloads and libraries live on one filesystem per media type so the arrs import with atomic hardlink moves. ## Changes - Add `apps/base/arrstack/` namespace with its own static CephFS PVs (`arrstack-media-tv`, `arrstack-media-movies`) + RWX PVCs (`media-tv`, `media-movies`) bound to the same rootPaths jellyfin uses; each namespace gets a unique PV name/volumeHandle pinned by claimRef. - Deploy sonarr (mounts media-tv RW), radarr (media-movies RW), prowlarr (config only), nzbget (both media PVCs RW); single replica, Recreate strategy, LinuxServer images via artifactapi dockerhub remote, PUID/PGID/TZ, probes, fsGroup for CephFS writability. - Per-app config PVCs on `cephrbd-fast-retain` (RWO, 5Gi) for the SQLite state; internal-only Gateway + HTTPRoute per app (traefik-internal, vault-issuer, external-dns `<app>.k8s.syd1.au.unkin.net`), no oauth yet. - nzbget: initContainer seeds `/config/nzbget.conf` (copy image template if absent, append managed path/category block once) and creates the media dirs; category `tv` -> `/media/tv/downloads`, `movies` -> `/media/movies/downloads`. - Wire ArgoCD: add `apps/overlays/*/arrstack` to the media ApplicationSet. (media AppProject already gains the arrstack destination + PersistentVolume whitelist on the base branch.) ## Depends on terraform-artifactapi PR #31 (allowlist `^linuxserver/` on the dockerhub remote) must be merged + applied before these pods can pull. ## Follow-up (terraform) Root folders (/media/tv/series, /media/movies/films), download-client wiring (host `nzbget`, port 6789, categories tv/movies) and API keys are configured later via terraform-arr. --------- Co-authored-by: Ben Vincent <neotheo@gmail.com> Co-authored-by: Ben Vin <neotheo@gmail.com> Reviewed-on: #366 Co-authored-by: unkin-agent <unkin-agent@unkin.net> Co-committed-by: unkin-agent <unkin-agent@unkin.net> |
