Kubernetes Network Policies (30 minutes)

As you saw throughout the course, Kubernetes separates projects through the notion of namespaces.

By default, Kubernetes enables Pods to communicate between namespaces, which goes against of the security principles that you learned about earlier: Least privilege. As a reminder, it is a security best practice to only allow the absolute necessary.

There is a very good Github project visualizing the different network policy configurations here.

Your exercise is the apply the different configurations and test them accordingly. It should give you a good overview on how to apply Kubernetes network policies in real life.
