Prior to Kubernetes 1.9, the default garbage collection policy for many controller resources was `orphan`.
This included ReplicationController, ReplicaSet, StatefulSet, DaemonSet, and

specify otherwise, dependent objects are orphaned by default. In Kubernetes 1.9, all kinds in the apps/v1
group version use a default garbage collection policy of `delete`.
