Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly MCC). This means everything you need is in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
Cluster versions compatibility¶
The following table provides the full support matrix for MOSK management and Cluster release versions.
Legend
Symbol |
Definition |
|---|---|
Latest supported cluster version to use for cluster deployment or update |
|
Deprecated cluster version that you must update to the latest supported cluster version |
|
Cluster version is not included in the product release yet. |
If the version you are looking for is not included in the table, it means that the version has become usupported, which prevents the automatic update of a management cluster. To resume receiving management cluster updates, you must update your MOSK cluster first.
For the detailed status description, refer to Cluster support statuses.
