[Docker] Librarys disappearing from Jellyfin

[TheDreadPirate]

You need to keep /config and /cache separate. The way you have it now both /config and /cache are in /volume1/docker/jellyfin. Once a day Jellyfin runs a cache cleanup job. Since /config is in the same host folder the cache cleanup job cleans up EVERYTHING. Including your database, user accounts, metadata, library settings. EVERYTHING.

Change your volume mounts to this.

Code:

volumes:
      - /volume1/docker/jellyfin/config:/config
      - /volume1/docker/jellyfin/cache:/cache
