  # Our current version of docker-compose doesn't allow extra_hosts which would be the best way
  # to add curcular dependency container links in this case. We cant upgrade docker-compose
  # without upgrading docker to 1.7, and we can't do that without upgrading the kernel on our
  # CentOS VM's. As such we are using the hostname hask below to allow primary and secondary
  # MongoDB nodes to communicate with each other.
