Current Series Release Notes¶

New Features¶

• Add an Ansible workflow to destroy a kolla-kubernetes deployment. This will be followed up with a container which runs this specific workflow.

• Adds helm chart for keepalived.

• Added support for outputing Prometheus metrics for python api based services and memcached.

New Features¶

• The placemenet API was enabled in the nova-control service chart. It defaults to enabled. The variable is: global.kolla.nova.all.placement_api_enabled

• Added support for Keystone Fernet Tokens.

• Config files are now generated by ansible in kolla-kubernetes

• Use selenium in the gate to test a login to Horizon.

New Features¶

• cinder control service package for deployment with kubernetes entrypoint.

• Helm chart to bring up OpenStack deployment, which includes: mariadb, rabbitmq, memcached, keystone, glance, cinder, neutron, nova and horizon. This compute kit uses iscsi/lvm as a backend for cinder volume.

Known Issues¶

• No upgrade technique is supported.

• Ceph Helm packaging is dangerous in its current state in Kolla-Kubernetes and only for testing purposes. Using ceph on the other hand within Kolla-Kubernetes works well.

• Version 2.0.2 of the Kolla containers (Mitaka) are used in this release. Some small subset of containers use version 3.0.2 as well as one 4.0.0 container (entrypoint). The kolla-kubernetes-core team will rectify this deficiency in 0.5.0.

Upgrade Notes¶

• There is no way to upgrade, however, a stable Helm API has been implemented. This paves the way for upgrades in the future.

Other Notes¶

• The kolla-kubernetes deliverable has not actively been using reno during development. As of this release the Kolla core team is rolling up the release notes for 0.4.0 and committed to creating reno notes for future commits where a releasenote would be applicable.
