kubectl apply -f ./manifests/hello-app/ kubectl get pods

without network policy kubectl logs --tail 10 -f $(kubectl get pods -oname -l app=hello) kubectl logs --tail 10 -f $(kubectl get pods -oname -l app=not-hello)

apply netpolicy kubectl apply -f ./manifests/network-policy.yaml

check now? kubectl logs --tail 10 -f $(kubectl get pods -oname -l app=hello) kubectl logs --tail 10 -f $(kubectl get pods -oname -l app=not-hello)

delete and apply different netpolicy kubectl delete -f ./manifests/network-policy.yaml kubectl create -f ./manifests/network-policy-namespaced.yaml

check now hello client logs kubectl logs --tail 10 -f $(kubectl get pods -oname -l app=hello)

deploy hello client in hello-apps namespace kubectl -n hello-apps apply -f ./manifests/hello-app/hello-client.yaml

now it will work kubectl logs --tail 10 -f -n hello-apps $(kubectl get pods -o name -l app=hello -n hello-apps)
