gcloud alpha compute instance-groups managed resize

NAME: gcloud alpha compute instance-groups managed resize - set managed instance group size
SYNOPSIS: gcloud alpha compute instance-groups managed resize NAME [--no-creation-retries] [--size=SIZE] [--stopped-size=STOPPED_SIZE] [--suspended-size=SUSPENDED_SIZE] [--region=REGION | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha 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

Name of the managed instance group to operate on.
FLAGS: --creation-retries

When instance creation fails retry it. Enabled by default, use --no-creation-retries to disable.

--size=SIZE

Target number of running instances in managed instance group.

--stopped-size=STOPPED_SIZE

Target number of stopped instances in managed instance group.

--suspended-size=SUSPENDED_SIZE

Target number of suspended instances in managed instance group.

At most one of these can be specified:

--region=REGION

Region of the managed instance group to operate on. If not specified, you might be prompted to select a region (interactive mode only).
A list of regions can be fetched by running:
gcloud compute regions list

Overrides the default compute/region property value for this command invocation.

--zone=ZONE

Zone of the managed instance group to operate on. If not specified, you might be prompted to select a zone (interactive mode only).
A list of zones can be fetched by running:
gcloud compute zones list

Overrides the default compute/zone property value for this command invocation.
