Due to upgrade issues with the Envoy gateway and the offline installation environments, upgrading to MKE 4k 4.1.3 is not recommended. These issues will be fixed in a future release. For version 4.1.3, Mirantis only supports fresh installations.

Kubernetes components

MKE 4k uses K0s to deploy core Kubernetes components, including:

• kubelet
• kube-apiserver
• kube-controller-manager
• kube-scheduler
• etcd

You can configure all of the Kubernetes components through the mke4.yaml configuration file.
