title: How to stop a kubernetes cluster?
body: <p>I started the claster on a Google compute engine with the help of a kube-up.sh. This script created the master node and minion group. After i dont need it anymore i want to stop a cluster and shutdown all VMs in order not waste money for working of instanses. When i shutdown it (i just shut down all my cluster VMs, because i dont know another way to do it) and then start again in some time my cluster wont work anymore. "kubectl get nodes"  dispalays not correct information about nodes ( For example i have A B C nodes == minions, it displays only D that even does not exist) and all comands works very very slow. Maybe i shutdown it not correct. How propery stop cluster and stop VMs in order to start it again in some time? (not delete)</p>
  
  <p>What cluster i have:</p>
  
  <pre><code>kubernetes-master             | us-central1-b
  kubernetes-minion-group-nq7f  | us-central1-b
  kubernetes-minion-group-gh5k  | us-central1-b
  </code></pre>
  
  <p>What displays "kubectl get nodes" command:</p>
  
  <pre><code>[root@common frest0512]# kubectl get nodes
  NAME                           STATUS                     AGE       VERSION
  kubernetes-master              Ready,SchedulingDisabled   7h        v1.8.0
  kubernetes-minion-group-02s7   Ready                      7h        v1.8.0
  kubernetes-minion-group-92rn   Ready                      7h        v1.8.0
  kubernetes-minion-group-kn2c   Ready                      7h        v1.8.0
  </code></pre>
  
  <p>Before shutdowning master node it was displayed correct (names and count of minions were the same).</p>
