Do we need to mount the Plex database into the plex_autoscan container?

[CLHatch]

I was setting up the plex_autoscan Docker container, basing the settings on an old config I had from a combined plex/plex_autoscan container (which used the original version of plex_autoscan). That old container I used had Plex and plex_autoscan in the same container, so of course all files were locally accessible.

While setting up your container, I managed to get everything apparently set up, and it apparently was able to see the Plex libraries through Docker (I believe I had to add a mount to the docker.sock file). But it was also spamming the logs with this:

2023/09/17 23:59:55 ERROR MAIN [MainThr] Unable to locate Plex DB file: PLEX_DATABASE_PATH=/config/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db

I just now got rid of that error by mounting the Plex library into the plex_autoscan container, but now the error is replaced with:

2023/09/18 00:31:33 ERROR UTILS  [MainThr] Process terminated with exit code: 1

This is my current compose for your container:

  plex_autoscan:
    image: ghcr.io/by275/autoscan:latest
    hostname: ${DOCKERHOSTNAME}
    container_name: plex_autoscan
    ports:
      - ${PLEXAUTOSCAN_PORT_3467}:3467
    environment:
      - PGID=${PGID}
      - PUID=${PUID}
      - UMASK=${UMASK}
      - TZ=${TZ}
    logging:
      driver: json-file
      options:
        max-file: ${DOCKERLOGGING_MAXFILE}
        max-size: ${DOCKERLOGGING_MAXSIZE}
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
      - ${DOCKERCONFDIR}/plex_autoscan:/config
      - ${DOCKERCONFDIR}/plex/Library:/config/Library:ro
      - ${DOCKERSTORAGEDIR}:/storage
    depends_on:
      - plex

I feel there must be something simple I'm missing... Any help would be appreciated.

Edit: Even though I'm getting that error, this does work:

Yes you should make autoscan accessible to plex database file but error is nothing to do with it. There seems no permission to access docker.sock for user with $PUID:$PGID. How about doing something like this? usermod -aG docker <username>

Makes sense. I believe your container uses user abc, so I created the docker group and added user abc to that group, then restarted for good measure. Unfortunately, still getting the permission issues.

Reproduced

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/pms/json": dial unix /var/run/docker.sock: connect: permission denied

and found the permission handling is missing https://github.com/sabrsorensen/alpine-plex_autoscan/blob/00eac031e74dd961242549451e135982fe0f1f66/root/etc/cont-init.d/10-init_user_and_fix_permissions#L52

It will be fixed soon.
