v1beta1/deployment: delete dependents

[josselin-c]

When removing a deployment I'd like the related replicaset/pods to be removed as well (this is the cascading mode in kubectl).

I tried to call Deployments("ns").Delete with the OrphanDependents option set to true or false but it didn't seem to do anything.
How can I do the cascading delete with client-go?

It's not supported yet. Currently cascading deletion is only supported for replicaset/replication controller (i.e., after you delete the rs or rc, the garbage collector controller will delete the pods). Cascading deletion of deployment will be supported after this PR gets merged: kubernetes/kubernetes#35676

As a workaround, you can take a look how kubectl deletes a deployment: https://github.com/kubernetes/kubernetes/blob/v1.6.0-alpha.0/pkg/kubectl/stop.go#L415. Basically it first scales down (supported in client-go) the deployment, waits the deployment.status reports the replicas reaches 0, and then delete the deployment.

Okay, I'll do this then and keep an eye on the PR.
Thanks for the help!
