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.

Port ranges

Standalone MKE clusters have a custom Kubernetes node port range of 32768-35535, as well as having ports 33000 and 33001 reserved for Ingress controller http and https, respectively. Due to CAPI limitations, for child clusters the Kubernetes node port range is 30000-32767, and it cannot be changed. In correlation, the node ports for the Ingress controller changed to 30000 and 30001, respectively.
