--- upgrade: - | This adds post_upgrade_tasks, ansible tasks that can be added to any service manifest (currently, pacemaker/cinder-volume for bug 1706951). These are similar to the existing upgrade_tasks in their format, however they will be executed *after* the docker/puppet config. So the order is upgrade_tasks, deployment steps (docker/puppet), then post_upgrade_tasks. Also like the upgrade_tasks these are serialised and you can use 'tags' with 'step0' to 'step6' (more can be added if needed).
