"Waiting for tearing down pods" when Kubernetes turns down

Question

I have a Kubernetes cluster installed in my Ubuntu machines. It consists of three machines: one master/node and two nodes.

When I turn down the cluster, it never stops printing "waiting for tearing down pods":

root@kubernetes01:~/kubernetes/cluster# KUBERNETES_PROVIDER=ubuntu ./kube-down.sh
Bringing down cluster using provider: ubuntu
Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)
No resources found

service "kubernetes" deleted

There is no pods nor services running when I turn it down. Finally, I have to force stop by killing processes and stoping services.

First we have to find out which rc is running :

kubectl get rc --namespace=kube-system

We have to delete Running rc :

kubectl delete rc above_running_rc_name --namespace=kube-system

Then cluster down script "KUBERNETES_PROVIDER=ubuntu ./kube-down.sh", will execute without Error "waiting for tearing down pods"

EXAMPLE ::

root@ubuntu:~/kubernetes/cluster# KUBERNETES_PROVIDER=ubuntu ./kube-down.sh

Bringing down cluster using provider: ubuntu Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)

No resources found No resources found service "kubernetes" deleted No resources found
