    # I like to be able to use psql on the host to connect to the database 
    # for maintenance. If you already have a postgres running you should remove 
    # the 'ports' section and uncomment 'expose'
    #expose:
    #- 5432
    ports:
      # Adding 127.0.0.1 ensures the port isn't exposed ON the host

    # Exposing 8008 (no TLS) on localhost means we can reverse proxy with nginx
    # 8448 is for federation and should be exposed on host
    # 3478 is for TURN (voip calls)
