The Mirantis Container Cloud GA release 2.11.0:
Introduces support for the Cluster release 7.1.0 that is based on Mirantis Container Runtime 20.10.5 and Mirantis Kubernetes Engine 3.4.0 with Kubernetes 1.20.
Introduces support for the Cluster release 5.18.0 that is based on Mirantis Kubernetes Engine 3.3.6 with Kubernetes 1.18 and Mirantis Container Runtime 20.10.5.
Supports the Cluster release 5.11.0 only for attachment of existing MKE 3.3.4 clusters. For the deployment of new or attachment of existing MKE 3.3.6 clusters, the latest available Cluster release is used.
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.
Before upgrading an existing managed cluster with StackLight deployed in HA mode to the latest Cluster release, add the StackLight node label to at least 3 worker machines as described in Upgrade managed clusters with StackLight deployed in HA mode. Otherwise, the cluster upgrade will fail.
