What would happen if we delete the ReplicaSet? As you might have guessed, both the ReplicaSet and everything it created (the Pods) would disappear with a single kubectl delete -f rs/go-demo-2.yml command. However, since ReplicaSets and Pods are loosely coupled objects with matching labels, we can remove one without deleting the other. We can, for example, remove the ReplicaSet we created while leaving the two Pods intact.
kubectl delete -f rs/go-demo-2.yml \
--cascade=false
We used the --cascade=false argument to prevent Kubernetes from removing all the downstream objects. As a result, we got the confirmation that replicaset "go-demo-2" was deleted. Let's confirm that it is indeed removed from the system.
kubectl get rs
As expected, the output states that no resources were found.
If --cascade=false indeed prevents Kubernetes from removing...
