  image: vovimayhem/app-dev:mri-2.2.3 # A ruby image with DTrace enabled for dev
  # Rails 4.2 now binds to 127.0.0.1 by default and not 0.0.0.0.
  # Start the server using bin/rails server -b 0.0.0.0 and that should sort it.

  # It's fine for development, do not do it in production:

  # With linked containers, Docker writes entries to the container's /etc/hosts.
  # We'll try here naming the entries docker will insert into the
  # container's /etc/hosts, so we can use more familiar URL's for our app - See
  # this container's environment section below:
