Compatibility matrix of component versions¶

The following tables outline the compatibility matrices of the most recent major Container Cloud and Cluster releases along with patch releases and their component versions. For details about unsupported releases, see Releases summary.

Major and patch versions update path

The primary distinction between major and patch product versions lies in the fact that major release versions introduce new functionalities, whereas patch release versions predominantly offer minor product enhancements, mostly CVE resolutions for your clusters.

Depending on the needs of your deployment, you can either update between only major Cluster releases, or update between the major Cluster releases receiving the patch updates in between.

Select the second option, which includes patch updates, only if you want to receive security fixes as soon as they become available and you are prepared to update your cluster often, approximately once in two weeks. Otherwise, you can update only between major Cluster releases as each subsequent major Cluster release includes patch Cluster release updates of the previous major Cluster release.

Container Cloud 2.23.5 or 2.24.0 automatically upgrades to the 2.24.1 patch release containing several hot fixes.

1

The major Cluster release 14.1.0 is dedicated for the vSphere provider only. This is the last Cluster release for the vSphere provider based on MCR 20.10 and MKE 3.6.6 with Kubernetes 1.24.

Container Cloud 2.25.1 introduces the patch Cluster release 16.0.1 that supports the vSphere provider on MCR 23.0.7 and MKE 3.7.2 with Kubernetes 1.27. For details, see External vSphere CCM with CSI supporting vSphere 6.7 on Kubernetes 1.27.

2(1,2)

In Container Cloud 2.24.3, docker-ee-cli is updated to 20.10.18 for MCR 20.10.17 to fix the following CVEs: CVE-2023-28840, CVE-2023-28642, CVE-2022-41723.

3(1,2,3,4,5,6,7,8,9)

OpenStack Antelope is supported as TechPreview since MOSK 23.3.
A Container Cloud cluster based on MOSK Yoga or Antelope with Tungsten Fabric is supported as TechPreview since Container Cloud 2.25.1.
OpenStack Victoria is supported until September, 2023. MOSK 23.2 is the last release version where OpenStack Victoria packages are updated.

If you have not already upgraded your OpenStack version to Yoga, Mirantis highly recommends doing this during the course of the MOSK 23.2 series. For details, see MOSK documentation: Upgrade OpenStack.

4(1,2,3)

Only Cinder API V3 is supported.

5(1,2,3)

VMware vSphere is supported on the following operating systems: RHEL 7.9 or 8.7, CentOS 7.9, Ubuntu 20.04.
RHEL 8.7 is generally available since Cluster releases 16.0.0 and 14.1.0. Before these Cluster releases, it is supported within the Technology Preview features scope.
CentOS 7.9 is supported as TechPreview.
For Ubuntu deployments, Packer builds a vSphere virtual machine template that is based on Ubuntu 20.04 with kernel 5.4.0-150-generic. If you build a VM template manually, we recommend installing the same kernel version 5.4.0-150-generic.

6(1,2,3,4)

Ceph Pacific supported in 2.23.0 is automatically updated to Quincy during cluster update to 2.24.0.
Ceph Pacific 16.2.11 and Rook 1.0.0-20230120144247 apply to major Cluster releases 12.7.0 and 11.7.0 only.
