## Changing a cluster configuration
(This procedure is currently unnecessarily convoluted. Expect it to get streamlined!)
Edit the cluster spec: `kops edit cluster --name ${NAME}`
View the changes you are going to apply `kops create cluster --name ${DRYRUN} --dryrun`
Apply the changes for real `kops create cluster --name ${DRYRUN}`
See which nodes need to be restarted `kops rolling-update cluster --name ${NAME} --region ${REGION}`
Apply the rolling-update `kops rolling-update cluster --name ${NAME} --region ${REGION} --yes`
