NAME
gcloud alpha compute instance-groups unmanaged delete - delete Compute Engine unmanaged instance groups
SYNOPSIS
gcloud alpha compute instance-groups unmanaged delete NAME [NAME …] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute instance-groups unmanaged delete deletes one or more Compute Engine unmanaged instance groups. This command just deletes the instance group and does not delete the individual virtual machine instances in the instance group. For example: 
gcloud alpha compute instance-groups unmanaged delete example-instance-group-1 example-instance-group-2 --zone us-central1-a

The above example deletes two instance groups, example-instance-group-1 and example-instance-group-2, in the us-central1-a zone.

POSITIONAL ARGUMENTS
NAME [NAME …]
Names of the instance groups to delete.
FLAGS
--zone=ZONE
Zone of the instance groups to delete. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/zone property: 

gcloud config set compute/zone ZONE

A list of zones can be fetched by running: 

gcloud compute zones list

To unset the property, run: 

gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

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. These variants are also available:
