Audiobookshelf Deployment Notes

Audiobookshelf runs as a StatefulSet in the media namespace. It manages audiobooks and podcasts with persistent metadata storage.

Image​

The deployment uses the official ghcr.io/advplyr/audiobookshelf:latest image. The container listens on port 80.

Configuration​

Audiobookshelf stores its configuration in /config on a Longhorn PersistentVolumeClaim. The application manages its own configuration through the web interface.

Storage​

Storage is split across three volume types:

  • /config uses a 5 Gi Longhorn PVC for application configuration and database
  • /metadata uses a 20 Gi Longhorn PVC for book covers, metadata cache, and transcoded audio files
  • /audiobooks and /podcasts mount subdirectories from the shared media-share NFS volume at audiobookshelf/audiobooks and audiobookshelf/podcasts respectively

The NFS share provides ReadWriteMany access so media files remain accessible to multiple pods and can be managed externally. Longhorn PVCs persist through pod restarts. /tmp stays ephemeral for scratch space.

Network​

The service exposes port 13378 externally while targeting the container port 80. HTTPRoute provides both internal and external gateway access at audiobookshelf.pc-tips.se.

Security​

The pod runs as user 2501 (matching other media applications) with:

  • runAsNonRoot: true
  • readOnlyRootFilesystem: true
  • seccompProfile: RuntimeDefault
  • All capabilities dropped

File system group ownership uses fsGroup: 2501 with OnRootMismatch policy for efficient permission handling.

Upgrades​

Update the image tag in the StatefulSet manifest. The volumeClaimTemplates ensure configuration and metadata persist across updates.

Debug​

Use kubectl logs to view application logs or kubectl exec for interactive access.
