Working with Kubernetes NetworkPolicies
By default, Kubernetes pods have unrestricted network access both inside and outside the cluster. However, it is often desirable to restrict network access to and from pods, particularly for security reasons. Kubernetes NetworkPolicies provide a flexible way to implement these networking restrictions, giving you control over all of the network traffic involving your pods. In this lab, walk through NetworkPolicies concepts, and examine some existing policies to determine how we can properly apply them to a pod.
