prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Set port numbers in docker compose via environment variables
  To provide more flexibility when setting up the ports for a given environment, we should not use static ports in `docker-compose`. Instead those ports should be extracted to the `.env` file.
  
  --- END ISSUE ---
  
  Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
  --- BEGIN FILES ---
