Kops behaves similarly to kubectl; you can edit the configuration files in the editor before actually doing any changes on the cluster. The kops update command will apply configuration changes, but will not modify the running infrastructure. To update the running cluster, you will need to execute the rolling-update command. The following will start the update or recreation process of the cluster's infrastructure:
$ kops rolling-update cluster –yes
Our fresh cluster is running, but it's empty. Let's deploy something.
