Support Portainer

As an option we could also include a portainer container with the following settings in docker compose:

  portainer:
    image: portainer/portainer
    restart: unless-stopped
    volumes:
      - '/var/run/docker.sock:/var/run/docker.sock'
    command: '--no-auth -H unix:///var/run/docker.sock'
    ports:
      - '8090:9000'
