title: How change the node count of a created cluster
body: <p>I created a cluster with kops in the AWS.</p>
  
  <pre><code>sudo kops create cluster --name=k8s.ehh.fun --state=s3://kops-state-ehh000 --zones=us-east-1a --node-count=3 --node-size=t2.micro --master-size=t2.micro --dns-zone=k8s.ehh.fun
  </code></pre>
  
  <p>And now a Would like to change the node-count without destroy the cluster. How can I do that?
  I tried :</p>
  
  <pre><code> sudo kops update cluster --name=k8s.ehh.fun --state=s3://kops-state-ehh000 --node-count=3 --node-size=t2.micro 
  </code></pre>
  
  <p>But I got : Error: unknown flag: --node-count</p>
