- DESCRIPTION
-
(PREVIEW)gcloud preview compute instance-groups managed resizeresize a managed instance group to a provided size.If you resize down, the Instance Group Manager service deletes instances from the group until the group reaches the desired size. Instances are deleted in arbitrary order but the Instance Group Manager takes into account some considerations before it chooses which instance to delete. For more information, see https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroupManagers/resize .
If you resize up, the service adds instances to the group using the current instance template until the group reaches the desired size.
