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.

Policy Controller

MKE 4k allows installation of third-party policy controllers for Kubernetes. OPA Gatekeeper is currently the only supported policy controller.

Configuration

You can configure the Policy Controller through the policyController section of the mke4.yaml configuration file.
