Installation refuses to connect to database [postgres]

[a-random-nerd11]

I'm trying to deploy Koel on my cachyos system using postgres db, but when I run the koel:init command, i get the following output:

   INFO  Remember, you can always install/upgrade manually using the guide at https://docs.koel.dev.

docker-compose.yml:

    depends_on:
      - database
    ports:

  database:

    volumes:
      - [path to db]:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=koel
      - POSTGRES_USER=koel

volumes:
  db:
    driver: local
  music:
    driver: local
  image_storage:
    driver: local
  search_index:
    driver: local

I've tried changing the port and path to database with no avail, and it refuses to connect when using the wizard that it presents me with.

Does anyone have a fix?
Thanks
