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 your deployment needs, you can either update only between major Cluster releases or apply patch updates between major releases. Choosing the latter option ensures you receive security fixes as soon as they become available. Though, be prepared to update your cluster frequently, approximately once every three 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.

Legend

Symbol	Definition
	Cluster release is not included in the Container Cloud release yet.
	Latest supported Cluster release to use for cluster deployment or update.
	Deprecated Cluster release that you must update to the latest supported Cluster release. The deprecated Cluster release will become unsupported in one of the following Container Cloud releases. Greenfield deployments based on a deprecated Cluster release are not supported. Use the latest supported Cluster release instead.
	Unsupported Cluster release that blocks automatic upgrade of a management cluster. Update the Cluster release to the latest supported one to unblock management cluster upgrade and obtain newest product features and enhancements.
	Component is included in the Container Cloud release.
	Component is available in the Technology Preview scope. Use it only for testing purposes on staging environments.
	Component is unsupported in the Container Cloud release.

The following table outlines the compatibility matrix for the Container Cloud release series 2.29.x.

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(1,2,3,4,5,6)

In Container Cloud 2.26.2, docker-ee-cli is updated to 23.0.10 for MCR 23.0.9 to fix several CVEs.
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(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17)

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. Since Container Cloud 2.26.0, support for this configuration is suspended. If you still require this configuration, contact Mirantis support for further information.
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(1,2,3,4,5,6,7)

Only Cinder API V3 is supported.

5(1,2,3,4,5)

Since Container Cloud 2.27.3 (Cluster release 16.2.3), the VMware vSphere configuration is unsupported. For details, see Deprecation notes.
VMware vSphere is supported on RHEL 8.7 or 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.
For Ubuntu deployments, Packer builds a vSphere virtual machine template that is based on Ubuntu 20.04 with kernel 5.15.0-116-generic. If you build a VM template manually, we recommend installing the same kernel version 5.15.0-116-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.

7(1,2,3)

Attachment of non Container Cloud based MKE clusters is supported only for vSphere-based management clusters on Ubuntu 20.04. Since Container Cloud 2.27.3 (Cluster release 16.2.3), the vSphere-based configuration is unsupported. For details, see Deprecation notes.

8(1,2,3,4,5)

The kernel version of the host operating system is validated by Mirantis and confirmed to be working for the supported use cases. Usage of custom kernel versions or third-party vendor-provided kernels, such as FIPS-enabled, assume full responsibility for validating the compatibility of components in such environments.

9(1,2,3,4,5,6,7,8,9,10,11)

On non-MOSK clusters, Ubuntu 22.04 is installed by default on management and managed clusters. Ubuntu 20.04 is not supported.
On MOSK clusters:
- Since Container Cloud 2.28.0 (Cluster releases 17.3.0), Ubuntu 22.04 is generally available for managed clusters. All existing deployments based on Ubuntu 20.04 must be upgraded to 22.04 within the course of 2.28.x. Otherwise, update of managed clusters to 2.29.0 will become impossible and management cluster update to 2.29.1 will be blocked.
- Before Container Cloud 2.28.0 (Cluster releases 17.2.0, 16.2.0, or earlier), Ubuntu 22.04 is installed by default on management clusters only. And Ubuntu 20.04 is the only supported distribution for managed clusters.

10(1,2,3,4,5,6,7,8)

In Container Cloud 2.27.1, docker-ee-cli is updated to 23.0.13 for MCR 23.0.11 and 23.0.9 to fix several CVEs.

11(1,2,3,4)

In Container Cloud 2.29.1 (Cluster releases 17.3.6, 16.4.1, and 16.3.6), docker-ee-cli is updated to 23.0.17 on MOSK clusters (MCR 23.0.15) and 25.0.9m1 on management clusters (MCR 25.0.8) to fix several CVEs.

12(1,2,3,4,5,6)

In Container Cloud 2.29.3 (Cluster releases 17.3.8, 16.4.3, and 16.3.8), docker-ee-cli is updated to 23.0.18 on MOSK clusters (MCR 23.0.15) and 25.0.10 on management clusters (MCR 25.0.8) to fix several CVEs.
