2.27.2

Important

For MOSK clusters, Container Cloud 2.27.2 is the continuation for MOSK 24.1.x series using the patch Cluster release 17.1.7. For the update path of 24.1 and 24.2 series, see MOSK documentation: Cluster update scheme.

The management cluster of a MOSK 24.1, 24.1.5, or 24.1.6 cluster is automatically updated to the latest patch Cluster release 16.2.2.

The Container Cloud patch release 2.27.2, which is based on the 2.27.0 major release, provides the following updates:

• Support for the patch Cluster release 16.2.2.

• Support for the patch Cluster releases 16.1.7 and 17.1.7 that represents Mirantis OpenStack for Kubernetes (MOSK) patch release 24.1.7.

• Support for MKE 3.7.11.

• Bare metal: update of Ubuntu mirror from ubuntu-2024-06-27-095142 to ubuntu-2024-07-16-014744 along with update of minor kernel version from 5.15.0-113-generic to 5.15.0-116-generic (Cluster release 16.2.2).

• Security fixes for CVEs in images.

This patch release also supports the latest major Cluster releases 17.2.0 and 16.2.0. And it does not support greenfield deployments based on deprecated Cluster releases. Use the latest available Cluster release instead.

For main deliverables of the parent Container Cloud release of 2.27.2, refer to 2.27.0.
