Current Series Release Notes

19.0.0.0rc1-61

New Features

  • Adds aarch64 iPXE support to the ironic-pxe image, by adding ipxe-bootimgs-aarch64 RPM package to Rocky Linux ironic-pxe images, and ensuring that an aarch64 iPXE binary is available in Ubuntu ironic-pxe images. No support for aarch64 iPXE in Debian images is included, as the distro packages do not install an aarch64 binary.

  • Adds a support for external account binding (EAB) in Let’s Encrypt.

  • Extends the support of externally-managed projects provided by the --docker-dir option with an ability to use configure_user jinja2 macros like Kolla built-in projects. The operator should specify “non-default” user details with <custom_user_name>-user configuration section and include info for uid and gid at least.

  • Updated the contents of Python package options in documentation to reflect latest customisation methods.

  • Improves logging format of kolla containers by adding timestamps with milliseconds, log levels, and a custom date format.

  • Add support for patching container images during build. See the build guide for details.

Known Issues

  • libnetfilter_log, which is required in neutron-l3-agent when fwaas_v2_log is enabled, is not available in official rpm repos and enabling this feature on rpm platforms will prevent neutron-l3-agent from running.

Upgrade Notes

  • Kolla toolbox is now using ansible-core 2.18

  • Bifrost is now using Ansible 11.x.

  • The use of UPPER_CONSTRAINTS_FILE environment variable was moved from base_pip_conf block in base Dockerfile to kolla_toolbox_pip_conf block in kolla-toolbox Dockerfile as the environment variable now only affects Kolla-toolbox build. Bifrost python upper-constraints now follows openstack-base’s python upper-constraints instead of UPPER_CONSTRAINTS_FILE environment variable.

  • Debian container image builds now use Dalmatian (2024.2) repositories of Debian OpenStack.

  • Users who parse Docker container logs should take into account that for example INFO:__main__:Validating config file is now YYYY-MM-DD HH:MM:SS.fff INFO Validating config file.

  • RabbitMQ version has been upgraded to 4.0.

  • Update Prometheus services to latest releases:

    • prometheus-alertmanager: 0.27.0 -> 0.28.0

    • prometheus-blackbox-exporter: 0.24.0 -> 0.25.0

    • prometheus-cadvisor: 0.49.1 -> 0.49.2

    • prometheus-elasticsearch-exporter: 1.7.0 -> 1.8.0

    • prometheus-memcached-exporter: 0.14.2 -> 0.15.0

    • prometheus-mtail: 3.0.0-rc54 -> 3.0.8

    • prometheus-mysqld-exporter: 0.15.1 -> 0.16.0

    • prometheus-node-exporter: 1.7.0 -> 1.8.2

    • prometheus 2.50.1 -> 2.55.1

    This upgrade migrates to a new TSDB format which is compatible with Prometheus v3.

  • uwsgi and uwsgi-plugin-python3 installation has been moved from barbican-base image to openstack-base.

Deprecation Notes

  • Building bifrost-deploy container image has been deprecated, in favor of a new ironic standalone deployment using ironic container images that will be implemented in kolla-ansible in the next cycles.

  • swift images have been deprecated for removal in 2025.2.

Bug Fixes

  • Fixes the inconsistency issue between config.json and real state in the container. LP#2060855

  • Python3-pip installs the dependent package tzdata and blocks the mount of the /etc/localtime file in docker. LP#2091161

  • Removes Git remote URLs after cloning to prevent credential exposure. LP#2098904

  • libnnetfilter_log has been added to deb platforms in order to support the fwaas_v2_log feature in neutron l3 agent.
