services:
  # `docker-compose-base.yml`
  # This compose file creates the `web`, `php`, and `init` containers.
  # This is the barebones stack required to run crimson.
  #
  # This service stack is ALWAYS enabled.

  web:
    # Crimson runs a nginx proxy to facilitate requets to PHP and requests
    # to the API (if enabled). Since it needs PHP to be running to send
    # requests, `php` is an added dependency.
    #
    # HTTP_PORT and HTTP_BIND sets what the external listen address will be for
    # the entire crimson stack.
