While using juju-deployer to deploy an environment with yaml file, and put openstack services into the containers. Chances are that some of the containers may not be able to created due to the race conditions.

In that case, I can clone the template manually, but juju-deployer fail to create because of the template is not stopped, so I guess there might be race condition in this situation
