Tidying Up
Removing all artifacts is simple: replace apply with delete in all kubectl-commands and execute them in reverse order:
kubectl delete -f 40-ingress-hello-world-a9s.yaml
kubectl delete -f 30-service-hello-world.yaml
kubectl delete -f 20-rs-hello-world.yaml
You can use the kubectl-commands you have learned to verify that all resources have actually been deleted.
