Preparing Kubernetes for Dynamic Admission Controllers

Admission controllers vet Kubernetes objects before running and can be a powerful part of a Kubernetes cluster. However, not all Kubernetes installs are set up to use admission controllers out of the box. In this lab, we'll check to see if the provided Kubernetes setup can use the provided admission controller and then set up our Kubernetes server to use the desired controller.
