freesailarr: MediathekArr as the tenth container, off by default (3.1.0+up1.0.0)
MediathekArr fakes a Usenet indexer towards Prowlarr and a SABnzbd downloader towards Sonarr/Radarr and fetches from the ARD and ZDF media libraries. Both consumers already share gluetun's network namespace, so they reach it over 127.0.0.1 - no service, no DNS, no ingress detour. Purely additive: the flag defaults to false and a default render is byte-identical to 3.0.5 (verified against the previous chart for both the default values and the CI values). The four things that fail silently without them: - A START GATE on gluetun. MediathekArr fetches its ruleset once at start and never retries; started before the tunnel it answers every Newznab search with 0 results while the container is up, Ready and quiet. Kubernetes cannot order two regular containers and an initContainer would deadlock, so the wait sits in front of the image entrypoint: poll gluetun's health server on 127.0.0.1:9999 and exec the entrypoint afterwards; on timeout the container exits rather than starting blind, because a crash loop is visible and an empty indexer is not. The startup probe budget (300s) deliberately outlasts the gate (180s). - incomplete/ AND complete/ ON THE SHARED DOWNLOADS CLAIM, not in an emptyDir. An emptyDir counts against the container's ephemeral-storage limit, and one large download would have the kubelet evict the whole pod with all ten containers - the trap ytdlp-web-player documents. - THE COMPLETE PATH SONARR SEES. The claim is mounted at /downloads exactly as sonarr/radarr mount it, and the chart sets DOWNLOAD_COMPLETE_PATH itself, so the SABnzbd complete_dir it reports is the same absolute path on both sides. - TWO PORTS: 5007 (SABnzbd role and UI, primary) and 5008 (Newznab role for Prowlarr), both declared to gluetun's firewall and both on one Service. The SABnzbd API is at /download/api - /api on 5007 answers with a misleading Newznab validation error. Further details: - Image pinned by digest (tag + digest): "latest" is a 2024 build, "beta" moves. Single-arch linux/amd64. The built-in helm-values manager cannot follow that pair, so renovate.json5 gets the chart's first customManagers block; verified by dry-run with two fixtures, since a matching and a broken rule look identical while the pin is current. - Hardened as measured: non-root, uid/gid from puid/pgid, readOnlyRootFilesystem: true, all capabilities dropped, no PUID/PGID. - Probes on measured 200 endpoints (there is no health endpoint): readiness and startup on /download/, liveness as an exec covering BOTH ports, because one container runs two processes and a wedged Newznab half is exactly what makes searches come back empty. - No ingress by default: the UI links its assets with root-absolute paths, so it can only be served at the root of a host; on the shared domain that root belongs to seerr. A sub-path fails the render instead of producing a broken UI. - values.yaml and NOTES.txt document the geo MARKER PROCEDURE (not a table of series), the escape route of a German exit and its price for the whole stack, the fail_message: null trap, and the HLS question as an open question. - CI: mediathekarr enabled in ci/freesailarr/test-values.yaml, install timeout raised to 1200s for the extra image and the gate.
