With the addition of new features in the Antelope release, the open source OpenStack platform is still utilised in conjunction with Kubernetes.

On March 22, 2023, OpenStack Antelope, the first significant upgrade of 2023, was made available for download. With Antelope, OpenStack has now had 27 iterations of its open source cloud platform since it was first developed as a collaboration between Rackspace and NASA in 2010. Since then, it has grown substantially.

The latest release is the first to adhere to the project’s revised release schedule for updates, which came into effect with the October 2022 release of the OpenStack Zed update. While there will still be two OpenStack platform releases annually, users will have the option to update only once a year if they like.

On March 22, OpenStack Antelope, the first significant update for the OpenStack cloud computing platform in 2023, was made available. As part of a strategy known as “LOKI,” support for Kubernetes is one of the main use cases for OpenStack. (Linux, OpenStack, and Kubernetes Infrastructure). In actuality, more than 85% of OpenStack deployments include Kubernetes, according to the OpenStack 2022 User Survey. A wide range of individuals and organisations continue to support OpenStack. Overall, 601 people from more than 110 organisations and over 40 countries contributed 9,794 modifications to the OpenStack Antelope release.

Key elements consist of:

  • New release cadence: Antelope is the first release under the new Skip Level Upgrade Release Process. (SLURP).
  • Kubernetes integration: The OpenStack Magnum project has increased support for Kubernetes.
  • Hardware support: A number of new storage-related hardware drivers have been included.
  • DNS updates: Now specified zones can be shared by several projects.
  • Updates on bare metal: The Ironic bare metal project now allows for the horizontal scaling of external API clients by sharding Ironic nodes using a shard key.
  • Power optimisation: Nova compute operators can control the power consumption of dedicated CPUs by switching off their governor or deactivating them when no instances are using them.
  • Computer performance improvement: Nova now enables PCI device scheduling via the Placement API on an opt-in basis.
  • Security improvements: Secure role-based access control is supported by both Neutron network and Glance image management components. (sRBAC).

Product manager at Canonical Tytus Kurek hailed the new release cadence as a significant advancement. Canonical offers its own commercially backed Ubuntu OpenStack distribution and contributes to OpenStack.
