I wonder if that would be possible to temporary stop the worker VM instances so they are not running at night time when I am not working on a cluster development. So far the only way I am aware of to "stop" the instances from running is to delete the cluster itself which I don't want to do. Any suggestions are highly appreciated.
The cluster was created following steps outlined in this guide.
Go to EC2 instances dashboard of your Node Group and from right panel in bottom click on Auto Scaling Groups then select your group by click on checkbox and click edit button and change Desired, Min & Max capacities to 0
