NAME
    gcloud compute instance-groups managed resize - set managed instance group
        size

SYNOPSIS
    gcloud compute instance-groups managed resize NAME --size=SIZE
        [--region=REGION | --zone=ZONE] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    gcloud compute instance-groups managed resize resize 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.

POSITIONAL ARGUMENTS
     NAME
