Network Policy with Calico
This lab covers the Kubernetes feature of Network Policy. The lab utilizes the `kops` installer to create a cluster using the Calico network overlay. The student is guided through the process of first creating a network policy that prohibits pod access, followed by another policy that grants pod access to certain clients and a named server.
