Also worth mentioning that the Train release added the kolla-ansible
deploy-containers command. From the release notes: This action will
only do the container comparison and deploy out new containers if that
comparison detects a change is needed. This should be used to get
updated container images, where no new config changes are needed,
deployed out quickly.

But for a weekly update I would recommend using deploy or reconfigure,
to make sure the configuration is updated if required.
