The OpenStack community released Antelope, OpenStack 2023.1, returning to “A” in its alphabetical release-naming protocol as it issues the 27th version of the world’s most widely deployed open source cloud infrastructure software. OpenStack is central to the LOKI trifecta (Linux, OpenStack, and Kubernetes Infrastructure), the open source standard for running modern cloud infrastructure. In Antelope, OpenStack contributors deliver a host of enhancements to the software’s rapidly expanding user base (166% increase in compute cores since 2020), including: a new release cadence, stronger integration with Kubernetes and other open source technologies, and expanded support for advanced hardware.
New Release Cadence: Antelope is the first in a new release cadence designed to ease the demands upon operators to upgrade every six months. Deployments will now be able to opt into a once-a-year upgrade cycle, upgrading with every Skip Level Upgrade Release Process or “SLURP” release. “Not-SLURP” releases will be available in each six-month interim for those who wish to upgrade more frequently. Antelope is a SLURP release; OpenStack Bobcat, the 28th release of OpenStack, is a non-SLURP release slated for October 2023.
Integration with Kubernetes: According to the 2022 OpenStack User Survey, Kubernetes is now deployed on over 85% of OpenStack deployments: 73% through vanilla Kubernetes itself. The rise in OpenStack and Kubernetes production integrations is further documented by an increase to 21% (up from just 16% last year) of users running production workloads with Magnum, the OpenStack service for container orchestration.
In Antelope, Magnum has been updated to support Kubernetes v1.24 running on Fedora CoreOS 36 and 37. Magnum has also been recertified as a Kubernetes orchestrator.
Hardware Enablement: In Antelope, OpenStack contributors continue to expand support for new hardware. For example:
Thank you to over 600 contributors from 110 different organizations who contributed to the OpenStack Antelope release.
