So we expose the pod resource type lab10server --port is 80. And then we are going to run the sleepyboxes in the default namespace. So sleepybox1 --image is busybox and --sleep 3600. And likewise for sleepybox2. Now that was the easy part. Next we need to work with network policies and as we want to work with network policies, what exactly do we need to do?

That means that the sleepybox1 pod needs a label. I also want to label on the default namespace because we are going for the network policy for a pod within a namespace from the…
