 While it is natural to expose web applications outside the cluster, exposing administrative features like the Administration Console and a T3 channel for WLST should be given more careful consideration.  There are alternative options that should be weighed.  For example, Kubernetes provides the ability to securely access a shell running in a container in a pod in the cluster.  WLST could be executed from such an environment, meaning the T3 communications are entirely within the Kubernetes cluster and therefore more secure.
