Introduce restart_bundle containers to detect config changes and restart pacemaker resources
During the containerization work we regressed on the restart of pacemaker resources when a config change for the service was detected. In baremetal we used to do the following: 1) If a puppet config change was detect we'd touch a file with the service name under /var/lib/tripleo/pacemaker-restarts/<service> 2) A post deployment bash script (extraconfig/tasks/pacemaker_resource_restart.sh) would test for the service file's existence and restart the pcs service via 'pcs resource restart --wait=600 service' on the bootstrap node. With this patchset we make use of paunch's ability do detect if a config hash change happened to respawn a temporary container (called <service>_restart_bundle) which will simply always restart the pacemaker service from the bootstrap node whenever invoked, but only if the pcmk resource already exists. For this reason we add config_volume and bind mount it inside the container, so that the TRIPLEO_CONFIG_HASH env variable gets generated for these *_restart_bundle containers. We tested this change as follows: A) Deployed an HA overcloud with this change and observed that pcmk resources were not restarted needlessly during initial deploy B) Rerun the exact same overcloud deploy with no changes, observed that no spurious restarts would take place C) Added an env file to trigger the of config of haproxy[1], redeployed and observed that it restarted haproxy only: Jun 06 16:22:37 overcloud-controller-0 dockerd-current[15272]: haproxy-bundle restart invoked D) Added a trigger [2] for mysql config change, redeployed and observed restart: Jun 06 16:40:52 overcloud-controller-0 dockerd-current[15272]: galera-bundle restart invoked E) Added a trigger [3] for a rabbitmq config change, redeployed and observed restart: Jun 06 17:03:41 overcloud-controller-0 dockerd-current[15272]: rabbitmq-bundle restart invoked F) Added a trigger [4] for a redis config change, redeployed and observed restart: Jun 07 08:42:54 overcloud-controller-0 dockerd-current[15272]: redis-bundle restart invoked G) Rerun a deploy with no changes and observed that no spurious restarts were triggered [1] haproxy config change trigger: parameter_defaults: ExtraConfig: tripleo::haproxy::haproxy_globals_override: 'maxconn': 1111 [2] mysql config change trigger: parameter_defaults: ExtraConfig: mysql_max_connections: 1111 [3] rabbitmq config change trigger (default partition handling is 'ignore'): parameter_defaults: ExtraConfig: rabbitmq_config_variables: cluster_partition_handling: 'pause_minority' queue_master_locator: '<<"min-masters">>' loopback_users: '[]' [4] redis config change trigger: parameter_defaults: ExtraConfig: redis::tcp_backlog: 666 redis::params::tcp_backlog: 666 Change-Id: I62870c055097569ceab2ff67cf0fe63122277c5b Co-Authored-By: Damien Ciabrini <dciabrin@redhat.com> Closes-Bug: #1775196
