Why does it when copying and pasting the url for SQLite dockercompose does docker not work correctly.

When I copy and paste the docker compose

version: '3'
services:
  podfetch:
    image: samuel19982/podfetch:latest
    user: ${UID:-1000}:${GID:-1000}
    ports:
      - "80:8000"
    volumes:
      - /home/####/podfetch-podcasts:/app/podcasts
      - /home/####/podfetch-db:/app/db
    environment:
      - POLLING_INTERVAL=60
      - SERVER_URL=http://localhost:80

volumes:
  podfetch-podcasts:
  podfetch-db:

It causes the docker to not run the app. But when i take out "user: ${UID:-1000}:${GID:-1000}" Is this a bug or is this just something wrong on my end? I'm using portainer as a gui to host my docker images but just copy and pasted the docker compose? Or is there just common knowledge that you're supposed to replace the "user: ${UID:-1000}:${GID:-1000}" with something else.

The syntax means either specify an environment variable UID in your docker compose or as default the uid 1000 is taken. So it should work rightaway by simply copying and pasting the code. There seems to be an issue with your pasted docker-compose. I can only see half of it and it is not really readable formatted.

The docked compose should be fixed in a readable format now

Thanks. I could reproduce the bug and found a fix for that. On my test system it was because I started the process as the wrong user. Thus the container process can't write to it. Either change the owner to be root or create a user with id 1000 and chown that to the created user. After that the SQLite database should spin up.

Looks like the README.md is also missing the following, but it is in the docker-compose.
- DATABASE_URL=sqlite:///app/db/podcast.db
