<div><br></div><div>This could be something simple, like automatically updating my local /etc/hosts with the correct alias between the cluster&#39;s name and the dynamic public IP.</div><div>Or a plugin to automatically assign an Elastic IP address to the master node: <a href="http://aws.amazon.com/articles/1346" target="_blank">http://aws.amazon.com/articles/1346</a></div>
