2.27.3 (current)

Important

For MOSK clusters, Container Cloud 2.27.3 is the first patch release of MOSK 24.2.x series using the patch Cluster release 17.2.3. 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, 24.1.6, or 24.1.7 cluster is automatically updated to the latest patch Cluster release 16.2.3.

The Container Cloud patch release 2.27.3, which is based on the 2.27.0 major release, provides the following updates:

  • Support for the patch Cluster releases 16.2.3 and 17.2.3 that represents Mirantis OpenStack for Kubernetes (MOSK) patch release 24.2.1.

  • MKE:

    • Support for MKE 3.7.12.

    • Improvements in the MKE benchmark compliance (control ID 5.1.5): analyzed and fixed the majority of failed compliance checks for the following components:

      • Container Cloud: iam-keycloak in the kaas namespace and opensearch-dashboards in the stacklight namespace

      • MOSK: opensearch-dashboards in the stacklight namespace

  • Bare metal: update of Ubuntu mirror from ubuntu-2024-07-16-014744 to ubuntu-2024-08-06-014502 along with update of the minor kernel version from 5.15.0-116-generic to 5.15.0-117-generic.

  • VMware vSphere: suspension of support for cluster deployment, update, and attachment. For details, see Deprecation notes.

  • 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.
