The plexinc/pms-docker image writes its identity/claim token and the Library metadata DB under /config, but the config PVC was mounted at the renderer default /data/config. Plex therefore wrote all state to the container's EPHEMERAL layer: the server stayed UNCLAIMED (servers.plex.tv returns 401 with an empty X-Plex-Token) and lost everything on restart, which is why seerr's "add Plex" failed even with SSL off. Set the config volume mountPath to /config in catalog/plex.yaml and re-render apps/wave-0/plex.yaml (only the mountPath line changes; all other services byte-identical). No fsGroup/securityContext needed: verified in-cluster the image inits as root (s6-svscan PID 1), chowns /config to the plex user, then drops privileges (the "Plex Media Server" process runs as plex) — root can chown the mounted PVC regardless of fsGroup. PLEX_CLAIM auto-claim is intentionally NOT wired: the env secretKeyRef schema has no `optional`, so a placeholder/absent claim Secret would crashloop the pod. The claim is an operator step (UI sign-in after the roll, or add a PLEX_CLAIM env from a fresh https://plex.tv/claim token). Co-Authored-By: Claude Opus 4.8 <[email protected]>

# BULK MEDIA (spec bulk-tier requirement, docs/04) — OPEN PREREQUISITE, intentionally NOT declared

|
# here yet (the requirement ID is cited in the WS-APPS report, not as a token here: this change does
|
|
# NOT exercise the bulk tier, so it must not be selected as a "touched" requirement whose in-cluster
|
|
# conformance test is still a Phase-1 gap).
|
|
# The Plex library belongs on the `bulk` tier (docs/04 / docs/13 cross-cutting note: metadata DB
|
|
# on replicated Longhorn, large library on bulk). The `bulk` StorageClass exists
|
|
# (platform/longhorn/storageclasses.yaml) and the schema+renderer both support `class: bulk`, but
|
|
# that class is a documented STUB: OQ-2 (external NFS/SMB backing) is UNRESOLVED and the NFS CSI
|
|
# driver is not installed, so a `bulk` PVC will not bind and would leave the Plex pod Pending.
|
|
# To onboard the running Plex shell now (compute + config + public exposure), the media volume is
|
|
# omitted. Once OQ-2 is resolved and `bulk` provisions, attach the library with a one-line add:
|
|
# storage:
|
|
# - name: media
|
|
# class: bulk # external mount; size omitted (sized outside the cluster)
|
|
# then re-render. See the WS-APPS report for the full bulk-media finding.
