Allow starting releem agent with non-root user

[major-mayer]

I created a docker compose configuration like this:

  releem-agent:
    depends_on:
      - db
    image: releem/releem-agent
    container_name: releem-agent
    user: 2004:2004
    environment:
     ...
    restart: unless-stopped
    volumes:
      - /tmp/.mysqlconfigurer/:/tmp/.mysqlconfigurer/

Now when i start the container, the following error message appears in the logs

releem-agent | /docker/entrypoint.sh: line 4: /opt/releem/releem.conf: Permission denied
releem-agent exited with code 1

Would it be possible to change the startup logic so that the root user is not required anymore?

Hello, @major-mayer
Could you please clarify the reason for requiring the container to run as a non-root user?

Hi,
I am trying to run all my Docker containers especially those with a bind mount as non-root for security reasons.

Apart from that i believe if Releem would run as root and write the mysql configuration it would have root as the user.
My MySQL containers runs as non-root so I would need to give the file other users read permissions.
If Releem could be started with an arbitrary user, this would not be necessary, since I could use the same user for Releem and MySQL.
