gcloud alpha compute instance-groups managed test-iam-permissions

NAME
gcloud alpha compute instance-groups managed test-iam-permissions - test IAM permissions for a Compute Engine managed instance group
SYNOPSIS
gcloud alpha compute instance-groups managed test-iam-permissions NAME --permissions=[PERMISSION,…] [--region=REGION     | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute instance-groups managed test-iam-permissions tests the IAM permissions that a caller has on a Compute Engine managed instance group.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

EXAMPLES
To test if the caller has compute.instanceGroupManagers.get and compute.instanceGroupManagers.update permissions on a zonal managed instance group my-mig in zone us-central1-a, run: 
gcloud alpha compute instance-groups managed test-iam-permissions my-mig --zone=us-central1-a --permissions=compute.instanceGroupManagers.get,compute.instanceGroupManagers.update

To test permissions on a regional managed instance group my-rmig in region us-central1, run: 

gcloud alpha compute instance-groups managed test-iam-permissions my-rmig --region=us-central1 --permissions=compute.instanceGroupManagers.get,compute.instanceGroupManagers.update
POSITIONAL ARGUMENTS
NAME
Name of the managed instance group to test IAM permissions for.
REQUIRED FLAGS
--permissions=[PERMISSION,…]
The set of permissions to check for the resource.
OPTIONAL FLAGS
At most one of these can be specified:
--region=REGION
Region of the managed instance group to test IAM permissions for. 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 test IAM permissions for. 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.
