The Memcached controller creates pods containing
OwnerReferences in their
metadata section. Referencing their owner ensures they will be deleted when the `memcached-sample` CR is deleted.
You can see the OwnerReference set on any of Memcached's pods:
kubectl get pods -o yaml | grep ownerReferences -A10
memcached-sample Custom Resource:
kubectl delete memcached memcached-sample
Thanks to OwnerReferences, all of the pods should be deleted. You can check with the familiar
kubectl get pods.
