The resultin pre_upgrade_rolling_steps_playbook will be executed in a node-by-node rolling fashion at the beginning of major upgrade workflow (before upgrade_steps_playbook). The current intended use case is special handling of L3 agent upgrade when moving Neutron services into containers. Special care needs to be taken in this case to preserve L3 connectivity of instances (with regard to dnsmasq and keepalived sub-processes of L3 agent). The playbook can be run before the main upgrade like this: openstack overcloud upgrade run --roles overcloud --playbook pre_upgrade_rolling_steps_playbook.yaml Partial-Bug: #1738768 Change-Id: Icb830f8500bb80fd15036e88fcd314bf2c54445d Implements: blueprint major-upgrade-workflow

pre_upgrade_rolling_tasks are added for use by the composable

service templates. The resulting

pre_upgrade_rolling_steps_playbook is intended to be run at the

beginning of major update workflow (before running the
|
|
upgrade_steps_playbook). As the name suggests, the tasks in this
|
|
playbook will be executed in a node-by-node rolling fashion.
