Wallaby Series Release Notes

12.0.0.0rc1-40

New Features

  • Adds the Monasca datasource plugin to the Grafana image. This allows Monasca users to visualise metrics in Grafana without using the Monasca Grafana fork.

  • Debian ‘bullseye’ is now used instead of ‘buster’. Bullseye is the next stable release of Debian, and is currently in a ‘freeze’ state. Several images gained Debian support with the move to bullseye.

Upgrade Notes

  • The monasca-grafana image has been dropped because it was using several deprecated components and was not buildable. Support for Monasca datasource was added into standard grafana instead.

  • Changed default of network_mode to host since Kolla-Ansible bootstrap-servers is deploying Docker without a bridge by default since Wallaby

Deprecation Notes

  • Support for building ppc64le container images has been deprecated in Wallaby cycle and will be removed in Xena.

  • The tempest and rally images are deprecated and will be removed in the Xena cycle. The reason is that these are not services of an OpenStack cloud but its clients.

Security Issues

  • Fixes security issue in Prometheus as per advisory.

Bug Fixes

  • Fixes an issue with logs going missing in the Fluentd pipeline by pinning td-agent to 4.0.*. LP#1930867

  • Fixes issues arising from the lack of Debian updates repo being enabled. LP#1931544

Other Notes

  • Debian images enable the Debian updates repo now. This is aligned with the base Debian image.

12.0.0.0rc1

New Features

  • Adds prometheus-v2-server image for Prometheus version 2.x.

  • Adds a new [DEFAULT] allowed-to-fail configuration option. It can be used to define a list of images which are allowed to fail during builds without marking the whole build as failed.

    The main use of this option is to keep CI systems in a working state despite some less important images failing.

  • Support for Debian binary (aka packaged) Masakari images.

  • Support for Ubuntu binary (aka packaged) Masakari images.

  • octavia-driver-agent image was added to support other Octavia providers than amphora.

Upgrade Notes

  • Kolla now no longer supports CentOS 8.2 and below. This is to support CentOS 8.3 without extra workarounds (please see the fixes section for more details). The promise is to support the latest CentOS 8 release which is 8.3 now.

  • RabbitMQ and Erlang packages are now installed from packagecloud.io (and PPA for Debian/Ubuntu) since bintray.com is getting shut down May 1st, 2021.

  • The Karbor project is no longer maintained and retired since Wallaby cycle . Its images and support is also removed since Wallaby cycle.

  • The zaqar image and related plugins are removed per the deprecation cycle.

  • Upgrades Elasticsearch, Logstash and Kibana (ELK) 6 images to ELK 7. Please see the upgrade notes in the official documentation

  • Three Neutron plugins are no longer provided by default in images: networking-ansible, networking-mlnx and vmware-nsx. The main reason is that they lag in synchronising with OpenStack release process. Their definitions have been moved to contrib/neutron-plugins directory. Please read the included README.rst in case you depend on them. Please note they are no longer included in published images.

Deprecation Notes

  • The chrony image is deprecated and will be removed in the Xena cycle.

  • Deprecates support for Prometheus v1.x. In Xena release cycle support for this image will be removed from Kolla.

  • Support for using Red Hat Enterprise Linux as base of container images was deprecated. Please migrate to using CentOS Stream 8 based images.

  • Fixes an issue with Swift containers failing to start in Ubuntu binary images. LP#1905279

  • CentOS images are using CentOS 8 Stream as a base.
