+### Addtional note on Deployments
+
+When using cascading deletes with deployments you *must* use _propagationPolicy: Foreground_
+to delete not only the ReplicaSets created, but also their Pods. If this type of _propagationPolicy_
+is not used, only the ReplicaSets will be deleted, and the Pods will be orphaned.
+See [kubeadm/#149](https://github.com/kubernetes/kubeadm/issues/149#issuecomment-284766613) for more information.
