Make .env file optional when passing variables through docker env

[0fflineuser]

Hi,
as I pass the explo env variables through the docker compose environment I don't need to share and .env file using a docker volume.

Would it be possible to not make the .env required for explo to start properly ? Right now it needs to exist for explo to start properly so I use a workaround with post_start.

Without the .env file created I get this error :

ERROR failed to load config from env vars context="wrong type ptr"

Here is my working explo compose service :

  explo:
    image: ghcr.io/lumepart/explo:latest
    restart: unless-stopped
    container_name: explo
    volumes:
      - storage_library_explo:/data/
      - storage_slskd_downloads:/slskd/
      # - $PLAYLIST_DIR:$PLAYLIST_DIR # for MPD. Both paths should be as defined in .env (e.g /my/playlists/:/my/playlists/)
      # - /path/to/cookies.txt:/opt/explo/cookies.txt # Path to optional cookies file (for yt-dlp)
    post_start:
      - command: touch /opt/explo/.env
        user: root
    environment:
      - TZ=${TZ} # Change this to the timezone set in ListenBrainz (default is UTC)
