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.

2.4.0

The Mirantis Container Cloud GA release 2.4.0:

• Introduces support for the Cluster release 5.11.0 that is based on Kubernetes 1.18, Mirantis Kubernetes Engine 3.3.4, and the updated version of Mirantis Container Runtime 19.03.14.

• Supports the Cluster release 6.10.0 that is based on the Cluster release 5.10.0 and supports Mirantis OpenStack for Kubernetes (MOSK) Ussuri.

• Still supports previous Cluster releases 5.10.0 and 6.8.1 that are now deprecated and will become unsupported in one of the following Container Cloud releases.

  Caution

  Make sure to update the Cluster release version of your managed cluster before the current Cluster release version becomes unsupported by a new Container Cloud release version. Otherwise, Container Cloud stops auto-upgrade and eventually Container Cloud itself becomes unsupported.

This section outlines release notes for the Container Cloud release 2.4.0.
