<p>I am trying to run a job on GKE for 5 mins and 50 nodes. However when i scale down instances it happens sequentially and thus costing me much more for a 4-5 min job.</p>

<p>Is there any way to paralelly delete GKE instances?</p>

<p>Kubernetes cluster has an underlying Instance Group.</p>

<p>I was able to delete the nodes in parallel by directly changing the number of nodes in Instance Group from 50 to 5.</p>

<p>All nodes were deleted within 30 seconds and GKE had also automatically updated the cluster size with the new value.</p>
