I recently wrote a blog post about how we could upgrade an host from Docker containers to Podman containers.
http://my1.fr/blog/openstack-containerization-with-podman-part-3-upgrades/ I managed to get this prototype actually tested in CI: https://review.openstack.org/#/c/608463/ http://logs.openstack.org/63/608463/10/check/tripleo-ci-centos-7-containerized-undercloud-upgrades/c958861/logs/undercloud/var/log/extra/docker/docker_allinfo.log.txt.gz http://logs.openstack.org/63/608463/10/check/tripleo-ci-centos-7-containerized-undercloud-upgrades/c958861/logs/undercloud/var/log/extra/podman/podman_allinfo.log.txt.gz Therefore, I am requesting feedback and reviews on: - openstack/paunch: rm the docker container during upgrade - https://review.openstack.org/#/c/608319/ - openstack/tripleo-upgrade: set container_cli for undercloud - https://review.openstack.org/#/c/608462/ - openstack/tripleo-quickstart: fs050: upgrade the undercloud to Podman containers - https://review.openstack.org/#/c/608463/ Thanks, -- Emilien Macchi
