how to add an node to my kops cluster? (node in here is my external instance) : <p>i have created a kubernetes cluster on AWS, as by following below instruction. All my master and worker nodes of Ubuntu OS type.</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>
