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.

Network options#

Common configuration file section: .spec.network

  • For child clusters, it is not possible to change the node port range. The mke4.yaml configuration file offers the .spec.network.nodePortRange field with 32768-35535 as the default value. No such field is available on a child cluster, however, and the node port range is instead set to the default Kubernetes value of 30000-32767.

  • The .spec.network.providers field in the mke4.yaml configuration file lists CNI providers, though only one of those providers can be enabled at a time. This is simplified for child clusters, with the field changed to spec.network.provider pointing to a single CNI provider.
