Rancher does a lot of the orchestrating of k8s clusters and works well in my experience.
Rancher is even more approachable and streamlined than Openshift. Yeah we need k8s to be more streamlined. It's fragmented cluster-something right now. There is no pride in making systems more complex nor there is pride in knowing how to operate them.
Currently mainstream k8s is text based, because it's still too fast moving and new. Creating a great GUI would be a serious overhead and there's not enough interest/demand for it. It'll come eventually.
