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 are fixed in the 4.1.4 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.
