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.

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.
