World failing to auto load

[TR7Mike]

I have a docker compose I've been running via a stack in portainer. Has been working fine, but with a couple of issues (license and world auto load). I've fixed the license now, but I can't figure out why the world won't auto load.

foundryvtt-live:
    image: felddy/foundryvtt:12.331
    container_name: foundryvtt-live
    hostname: foundryvtt-live
    #env_file:
    #  - stack.env
    environment:
      - TZ=Europe/London
      - PUID=1000
      - PGID=1000      
      - FOUNDRY_HOSTNAME=foundryvtt-live
      - CONTAINER_CACHE=/data/container_cache
      - FOUNDRY_ADMIN_KEY=MyPass
      #- FOUNDRY_PASSWORD="mypass"
      #- FOUNDRY_USERNAME="[email protected]"
      - FOUNDRY_LICENSE_KEY="MyKey"
      #- FOUNDRY_RELEASE_URL=""
      - FOUNDRY_MINIFY_STATIC_FILES=true
      - FOUNDRY_PROTOCOL=4
      - CONTAINER_PRESERVE_CONFIG=true
      - FOUNDRY_TELEMETRY=false
      - FOUNDRY_WORLD="maincampaign"
      - CONTAINER_VERBOSE=true
    volumes:
      - /home/linux/docker_volumes/foundryvtt-live:/data      
    ports:
      - "9100:30000"
    restart: unless-stopped

Here is the output from the portainer log:

Seems to indicate that the world isn't being passed through. I have tried putting the environment variables in an env file, but that doesn't work either (same no launch issue).

[felddy]

Because you have set CONTAINER_PRESERVE_CONFIG to true.

Normally new options.json and admin.txt files are generated by the container at each startup. Setting this to true prevents the container from modifying these files when they exist. If they do not exist, they will be created as normal.

See:

Thanks, worked a treat. I had read somewhere that this was needed to stop the continuous prompting for sharing of telemetry, etc.

[felddy]

Take a look at setting FOUNDRY_TELEMETRY to true or false.
