body: <p>I have created a Kubernetes cluster on AWS by following the instructions below. All my master and worker nodes are running Ubuntu.</p>

  <p>I am aware on how to increase or decrease the number of nodes in my cluster using cluster updates which kubernetes spins up a new node for us,</p>
  <p>However i was wondering, is it possible to attach my external aws instance(for eg: an instance with same OS like ubuntu) to my existing kops cluster?</p>
