Current Series Release Notes¶

31.0.0.0rc1-116¶

Added support for deployments on CentOS 10 Stream

A series of changes were backported for CentOS 10 Stream support for both deploy and target hosts.

A behavior for AIO setup regarding network configuration has been changed. Instead of directly applying all configuration during boostrap-aio.sh script, script will produce another variable file user_variables_systemd.yml with intended configuration. Variable will be consumed and applied by openstack_hosts role, which will be launched during setup-hosts (setup-everyting) playbook.

In order to align approach on playbooks location and usage, upgrade playbooks were moved from upgrade_utilities of the integrated repository to openstack.osa collection:
- upgrade-utilities/deploy-config-changes.yml -> openstack.osa.upgrade.deploy_config_changes
- upgrade-utilities/galera-cluster-rolling-restart.yml -> openstack.osa.tools.galera_cluster_rolling_restart
- upgrade-utilities/nova-restore-compute-id.yml -> openstack.osa.tools.nova_restore_compute_id

Added support for defining custom error files using haproxy_errorfiles. These files can be distributed alongside haproxy_static_files_extra.

It was discovered that LXC 5.0.3 in Ubuntu 24.04 (Noble Numbat) contains packaging issue resulting in apparmor profiling conflicts. A temporary workaround has been applied in lxc_hosts role to apply a hotfix to the profile. However, it will be wiped with the next update of liblxc-common package. Please, check the bug #2110635 for more details on the issue.

Docker mode for zun-compute has been switched to “local” mode. This means, that supporting etcd cluster is no longer required for Zun to operate. If you want preserve old behavior, you will need to pin Docker and Containerd versions back along with adding zun_docker_kv_storage: etcd to user_variables.yml

For deployments with Zun, underlying software versions were upgraded to: * Docker 20.10.24 -> 27.5.1 * Containerd 1.6.20 -> 1.7.27 * Kata 3.1.0 -> 3.16.0

Variables zun_docker_kv_storage and zun_docker_kv_group were deprecated and will be removed in the next release.

The horizon_default_role_name (default member) Keystone role existence is no longer ensured by the Horizon role. It is expected that the role defined by horizon_default_role_name already exists in Keystone and was bootstrapped via keystone-bootstrap command during os_keystone execution. You can leverage opestack.osa.openstack_resources playbook to create extra roles if you need/want to use non-default value for the horizon_default_role_name variable

os_neutron role was ignoring actual exit code of aa-disable command, when it was exiting abnormally. It could result in unobvious failures later in neutron agents. This was fixed and the role will fail if aa-disable fails to disable required apparmor profiles instead of suppressing the issue.

With change of policy regarding stored versions of MariaDB in mirror.mariadb.org, currently pinned MariaDB versions were removed from the repo. With a switch to archive.mariadb.org, this should resolve failing installation for MariaDB.
