Testing a Dynamic Admission Controller for Kubernetes

Kubernetes dynamic admission controllers let us validate or mutate our Kubernetes request objects to either approve, deny, or change the object upon creation. In this hands-on lab, we review a provided admission controller that add labels to a resource and then create the needed configuration to test it. We'll also see if we can update the deployment code to use our own labels.
