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.

2.3.0

The Mirantis Container Cloud GA release 2.3.0:

• Introduces support for the Cluster release 5.10.0 that is based on Kubernetes 1.18 and the updated versions of Mirantis Kubernetes Engine 3.3.4 and Mirantis Container Runtime 19.03.13.

• Introduces support for 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 5.9.0 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.
