Current Series Release Notes¶
17.0.0.0rc1-117¶
New Features¶
Adds a new variable
prometheus_ceph_exporter_interval
for controlling Ceph’s metrics scrape interval.
Exposes a flag,
bifrost_enable_ironic_inspector
, to enable ironic-inspector in Bifrost. This option defaults toTrue
as it can be useful for backwards compatibility. It is still possible to use native in-band inspection when Ironic Inspector is enabled by settinginspect_interface
toagent
. Please see the Ironic documentation for more details.
Implements [Configure tap-as-a-service plugin on neutron containers]. Adds the needed changes and configurations in order to use the neutron plugin, tap-as-a-service, to create por mirrors using openstack tap commands. Blueprint configure-taas-plugin
Implements [Enable Fluentd Plugin Systemd]. Adds the needed changes and configurations in order to use the fluentd plugin, systemd, to read logs from /var/log/journal by default. This allows us to read and manipulate this logs for monitoring purposes.
These logs will be sent to OpenSearch by default, to disable this behavior, set the value of the variable
enable_fluentd_systemd
tofalse
in the configuration file/etc/kolla/globals.yml
.By default, when enabling central logging, we also enable the
systemd
plugin. To disable this behavior when central logging is enabled, set the value of the variableenable_fluentd_systemd
tofalse
in the configuration file/etc/kolla/globals.yml
.fluent-plugin-systemd source: https://github.com/fluent-plugin-systemd/fluent-plugin-systemd
Adds new variables to be used by the neutron role,
neutron_dns_integration
andneutron_dns_domain
. They allow to enable/disable internal/external DNS integrations, or their combinations.
Removed configuration and deployment of
prometheus-haproxy-exporter
as its repository is now archived. We now use the native support for Prometheus which is now built into HAProxy. For consistency this is exposed on theprometheus_haproxy_exporter_port
port.prometheus-haproxy-exporter
containers and config are automatically removed.
Enable elevated access for project scoped service role in Ironic. Ironic recently started to enforce new policies and scope. And Ironic is one of the sole openstack project which need system scope for some admin related api calls. However Ironic also started to allow project-scope behaviour for service role with setting
rbac_service_role_elevated_access
. This change enables this setting to get similar behaviour of service role as other openstack projects.
Add the service role to ironic service users. Ironic recently enforced new policy validation and added service role support.
Adds support for setting the max fail percentage for Ansible plays via
kolla_max_fail_percentage
. It can also be set on a per-service basis, e.g.nova_max_fail_percentage
.
Set a log retention policy for OpenSearch via Index State Management (ISM). Documentation.
Configure Skyline’s Prometheus connection to make the Monitor Center work. The latest Skyline Console has now a Monitor Center in the administrator view that displays information from Prometheus. For that to work the Prometheus connection needs to be set up in skyline.yaml.
Allow overriding of Skyline configuration files by supplying your own version of nginx.conf for Skyline Console, gunicorn.py and skyline.yaml for Skyline API Server. Place the files in the skyline subfolder of your Kolla config directory, skyline.yaml will be merged with the Kolla provided version.
Upgrade Notes¶
Minimum supported Ansible version is now
8
(ansible-core 2.15) and maximum supported is9
(ansible-core 2.16).
Changes configuration variable
designate_enable_notifications_sink
tono
which configures notifications for designate in neutron, nova and control deployment ofdesignate-sink
which is now optional.Operators that want to keep the previous behavior should set this to
true
.
The
grafana
volume is no longer used. If you wish to automatically remove the old volume, setgrafana_remove_old_volume
totrue
. Note that doing this will lose any plugins installed via the cli directly and not through kolla. If you have previously installed Grafana plugins via the Grafana UI, or CLI, you must change to installing them at image build time. The grafana volume, which will contain existing custom plugins, will be automatically removed in the D release.
Due to the change from using the
prometheus-haproxy-exporter
to using the native support for Prometheus which is now built into HAProxy, metric names may have been replaced and/or removed, and in some cases the metric names may have remained the same but the labels may have changed. Alerts and dashboards may also need to be updated to use the new metrics. Please review any configuration that references the old metrics as this is not a backwards compatible change.
Horizon role was reworked to preffered local_settings.d configuration model. Files
local_settings
andcustom_local_settings
were renamed to_9998-kolla-settings.py
and_9999-custom-settings.py
Users who use horizon’s custom configuration have to change the names of those files in/etc/kolla/config/horizon
also.
Added log retention in OpenSearch, previously handled by Elasticsearch Curator. By default the soft and hard retention periods are 30 and 60 days respectively. If you are upgrading from Elasticsearch, and have previously configured
elasticsearch_curator_soft_retention_period_days
orelasticsearch_curator_hard_retention_period_days
, those variables will be used instead of the defaults. You should migrate your configuration to use the new variable names before the Caracal release.
If credentials are updated in
passwords.yml
kolla-ansible is now able to update these credentials in the keystone database and in the on disk config files.The changes to
passwords.yml
are applied oncekolla-ansible -i INVENTORY
reconfigure has been run.If you want to revert to the old behavior - credentials not automatically updating during reconfigure if they changed in
passwords.yml
- you can specify this by settingupdate_keystone_service_user_passwords: false
in your globals.yml.Notice that passwords are only changed if you change them in
passwords.yml
. This mechanism is not a complete solution for automatic credential rollover. No passwords are changed if you do not change them insidepasswords.yml
.
Bug Fixes¶

Fixes non-persistent Neutron agent state data. LP2009884
Fixes
ovs-dpdk
images pull. LP#[2041864]
Starting with ansible-core 2.13, list concatenation format is changed which resulted in inability to override horizon policy files. See LP#2045660 for more details.
Fixes long service restarts while using systemd LP#2048130.
Fixes an issue with high CPU usage of the cAdvisor container by setting the per-container housekeeping interval to the same value as the Prometheus scrape interval. LP#2048223
Fixes glance image import LP#2048525.
Fixes Nova operations using the
scp
command, such as cold migration or resize, on Debian Bookworm. LP#2048700

Fixes mariadb role deployment when using Ansible check mode. LP#2052501

openvswitch
bridge creation whenneutron_bridge_name
was specified as two bridges. LP#2056332
Fixes the use of redis as coordination backend. LP#2056667
Fix the wrong configuration of the ovs-dpdk service. this breaks the deployment of kolla-ansible. For more details please see bug 2058372.
Updated configuration of service user tokens for all Nova and Cinder services to stop using admin role for service_token and use service role.
See LP#[2004555] and LP#[2049762] for more details.
Fixes enabled usage audit notifications when they are not needed. See LP##2049503.

Fixes Docker health check for the
sahara_engine
container. LP#2046268
Fix a trove deployment bug where trove guest-agent failed to connect to RabbitMQ due to the missing of the oslo_messaging_rabbit config in guest-agent.conf. see bug 2048822
Fix trove failed to discover swift endpoint due to the missing of service_credentials in guest-agent.conf. see bug 2048829
Fix the Octavia jobboard boolean value. See https://bugs.launchpad.net/kolla-ansible/+bug/2058046 for details.
Fixes bug #2039498 where the grafana docker volume was bind mounted over Grafana plugins installed at image build time. This is fixed by copying the dashboards into the container from an existing bind mount instead of using the
grafana
volume. This however leaves behind the volume which can be removed by settinggrafana_remove_old_volume
totrue
. Please note that any plugins installed via the cli directly and not through kolla will be lost when doing this. In a future releasegrafana_remove_old_volume
will default totrue
.

Changes to service user passwords in
passwords.yml
will now be applied when reconfiguring services.This behaviour can reverted by setting
