# Application: -----------------------------------------------------------------
# We'll also use this configuration (&app_base) for the worker and test
# containers:
web: &app_base
  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.
  # http://stackoverflow.com/questions/27799260/rails-4-2-server-port-forwarding-on-vagrant-does-not-work
  # It's fine for development, do not do it in production:
  command: rails server -p 3000 -b 0.0.0.0
  ports:
    - "3000:3000" # Bind host port 3000 to app HTTP port 3000
  volumes:

  # container's /etc/hosts, so we can use more familiar URL's for our app - See
