Release Compatibility Matrix

The Release Compatibility Matrix describes the cloud configurations that have been supported by the product over the course of its lifetime and the path a MOSK cloud can take to move from an older configuration to a newer one.

For each MOSK release, the document outlines the versions of the product major components, the valid combinations of these versions, and the way every component must be updated or upgraded.

For a more comprehensive list of the product subcomponents and their respective versions included in each MOSK release, refer to Release Notes, or use the Releases section in the Container Cloud UI or API.

Mirantis Container Cloud will update itself automatically as long as the release of each managed cluster has either supported or deprecated status in the new version of Container Cloud.

A deprecated cluster release becomes unsupported in one of the following Container Cloud releases. Therefore, we strongly recommend that you update your deprecated MOSK clusters to the latest supported version as described in Upgrade paths.

1(1,2)

All clusters initially deployed using MOSK 22.2 or earlier versions support Ubuntu 18.04. Starting from MOSK 22.3, all newly deployed clusters support Ubuntu 20.04 regardless of OpenStack and Tungsten Fabric versions.

The implementation and verification of the Ubuntu 18.04 to 20.04 upgrade procedure has been scheduled for the 2023 year.
