2.18.0

The Mirantis Container Cloud GA release 2.18.0:

• Introduces support for the Cluster release 11.2.0 that is based on Mirantis Container Runtime 20.10.8 and Mirantis Kubernetes Engine 3.5.1 with Kubernetes 1.21.

• Introduces support for the Cluster release 7.8.0 that is based on Mirantis Container Runtime 20.10.8 and Mirantis Kubernetes Engine 3.4.7 with Kubernetes 1.20.

• Supports the Cluster release 8.6.0 that is based on the Cluster release 7.6.0 and represents Mirantis OpenStack for Kubernetes (MOSK) 22.2.

• Does not support greenfield deployments on deprecated Cluster releases 11.1.0, 8.5.0, and 7.7.0. Use the latest 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.

Caution

Due to the known issue 24802 affecting clusters with enabled proxy, the Container Cloud release upgrade from 2.17.0 to 2.18.0 can trigger automatic update of managed clusters to the latest available Cluster releases in their respective series. For details, see the known issue 24802.
