## Disabling GLBC
@ -87,20 +86,20 @@ Since GLBC runs as a cluster addon, you cannot simply delete the RC. The easiest
* IFF you want to tear down existing L7 loadbalancers, hit the /delete-all-and-quit endpoint on the pod:
```console
$ kubectl get pods --namespace=kube-system
NAME READY STATUS RESTARTS AGE
l7-lb-controller-7bb21 1/1 Running 0 1h
$ kubectl exec l7-lb-controller-7bb21 -c l7-lb-controller curl http://localhost:8081/delete-all-and-quit --namespace=kube-system
$ kubectl logs l7-lb-controller-7b221 -c l7-lb-controller --follow
...

$ kubectl get pods --namespace=kube-system

* Nullify the RC (but don't delete it or the addon controller will "fix" it for you)
```console
$ kubectl scale rc l7-lb-controller --replicas=0 --namespace=kube-system

$ kubectl scale rc l7-lb-controller --replicas=0 --namespace=kube-system
