Problem statement: Damien and I observed that during an OSP15 redeploy without any changes to THT a number of containers are re-run by paunch and that should not happen. It causes long delays and creates a lot of extra unneeded downtime. Only containers that have the following snippet in THT should be rerun on a redeploy (i.e. containers where the config or some environment changes). For example mysql_init_bundle: environment: # NOTE: this should force this container to re-run on each # update (scale-out, etc.) - list_join: - '' - - 'TRIPLEO_DEPLOY_IDENTIFIER=' - {get_param: DeployIdentifier} The above is the typical way in tripleo to say "we want this container to run at every redeploy" But we see a truckload of containers being rerun, even ones that do not have the above code. For example (short list, the real list is a lot longer): mysql_restart_bundle mysql_bootstrap mysql_data_ownership We are reasonably certain that the restart is not being triggered due to changes in /var/lib/config-data/puppet-generated/<service> as we observed no md5sum changes (except swift) during a redeploy. The patch that broke things is the following one: https://review.opendev.org/#/c/642910/ commit 85fb2ed4d3f7e42840842f2bdec617e33d6ba4ef Author: Luke Short <ekultails> Date: Fri Jul 5 11:31:13 2019 -0400 Handle defined containers that are stopped. Delete the stopped container and recreate it to ensure there are no local modifications to the container. Change-Id: Ia3fe06dd221d0894a5de2c18beaa48ba29440003 Resolves: rhbz#1674517 Signed-off-by: Luke Short <ekultails> Reverting this patch fixes things for us. This patch, while it likely did fix Lukas' concerns in https://bugzilla.redhat.com/show_bug.cgi?id=1674517, needs some changes to only delete and start stopped container *if* they have some sort of "restart:" policy in their container definition. For example: docker_config: step_1: memcached: start_order: 0 image: {get_param: ContainerMemcachedImage} net: host privileged: false restart: always healthcheck: test: /openstack/healthcheck volumes: list_concat: - {get_attr: [ContainersCommon, volumes]} - - /var/lib/config-data/memcached/etc/sysconfig/memcached:/etc/sysconfig/memcached:ro command: ['/bin/bash', '-c', 'source /etc/sysconfig/memcached; /usr/bin/memcached -p ${PORT} -u ${USER} -m ${CACHESIZE} -c ${MAXCONN} $OPTIONS'] It should not go around restarting containers what do not have a restart: policy set unless something in the config changed as that is the implied contract paunch exposed since its inception and which we rely on for a number of things (in particular we were debugging the excessive restart cause by the HA restart_bundle containers)
