gcloud alpha compute instance-groups managed suspend-instances

NAME: gcloud alpha compute instance-groups managed suspend-instances - suspend instances owned by a managed instance group
SYNOPSIS: gcloud alpha compute instance-groups managed suspend-instances NAME --instances=INSTANCE,[INSTANCE,…] [--force] [--region=REGION | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha compute instance-groups managed suspend-instances suspends one or more instances from a managed instance group, thereby reducing the targetSize and increasing the targetSuspendedSize of the group.
The command returns the operation status per instance, which might be FAIL, SUCCESS, or MEMBER_NOT_FOUND. MEMBER_NOT_FOUND is returned only for regional groups when the gcloud command-line tool wasn't able to resolve the zone from the instance name.
EXAMPLES: To suspend an instance from a managed instance group in the us-central1-a zone, run:
gcloud alpha compute instance-groups managed suspend-instances example-managed-instance-group --zone=us-central1-a --instances=example-instance
POSITIONAL ARGUMENTS: NAME

Name of the managed instance group to operate on.
REQUIRED FLAGS: --instances=INSTANCE,[INSTANCE,…]

Names of instances to suspend.
OPTIONAL FLAGS: --force

Immediately suspend the specified instances, skipping the initial delay, if one is specified in the standby policy.

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.
GCLOUD WIDE FLAGS: These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
Run $ gcloud help for details.
NOTES: This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. This variant is also available:
