  # TODO: This hosts string is wrong; rabbit and utility containers were included. Use https://review.openstack.org/#/c/464703/ instead
  # GOAL: Provide a way to roll through API containers, then do rabbitmq and mariadb in separate playbooks. Get them to gating team,
  #       then transition work for integrating artifacts to someone else
