Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

We are bringing MCC documentation into the MOSK documentation set so you can find everything in one place. The current MCC documentation portal will be retired soon, so we encourage you to update your bookmarks and workflows for continued easy access to the latest content.

2.22.0

The Mirantis Container Cloud GA release 2.22.0:

• Introduces support for the Cluster release 11.6.0 that is based on Mirantis Container Runtime 20.10.13 and Mirantis Kubernetes Engine 3.5.5 with Kubernetes 1.21.

• Supports the Cluster release 12.5.0 that is based on the Cluster release 11.5.0 and represents Mirantis OpenStack for Kubernetes (MOSK) 22.5.

• Does not support greenfield deployments on deprecated Cluster releases 11.5.0 and 8.10.0. Use the latest available Cluster releases of the series instead.

  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.
