NAME: gcloud alpha compute instance-groups list-instances - list instances present in the instance group
SYNOPSIS: gcloud alpha compute instance-groups list-instances NAME [--regexp=REGEXP, -r REGEXP] [--region=REGION | --zone=ZONE] [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,…]] [--uri] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha compute instance-groups list-instances list instances in an instance group.
The required permission to execute this command is compute.instanceGroups.list. If needed, you can include this permission, or choose any of the following preexisting IAM roles that contain this particular permission:

Compute Admin

Compute Viewer

Compute Instance Admin (v1)

Compute Instance Admin (beta)

Compute Network Admin

Compute Network Viewer

Editor

Owner

Security Reviewer

Viewer

POSITIONAL ARGUMENTS: NAME

Name of the instance group to operate on.
FLAGS: --regexp=REGEXP, -r REGEXP

A regular expression to filter the names of the results on. Any names that do not match the entire regular expression will be filtered out.

At most one of these can be specified:

--region=REGION

Region of the 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 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.
LIST COMMAND FLAGS: --filter=EXPRESSION

Apply a Boolean filter EXPRESSION to each resource item to be listed. If the expression evaluates True, then that item is listed. For more details and examples of filter expressions, run $ gcloud topic filters. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--limit=LIMIT

Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--page-size=PAGE_SIZE

Some services group resource list output into pages. This flag specifies the maximum number of resources per page. The default is determined by the service if it supports paging, otherwise it is unlimited (no paging). Paging may be applied before or after --filter and --limit depending on the service.

--sort-by=[FIELD,…]

Comma-separated list of resource field key names to sort by. The default order is ascending. Prefix a field with ``~´´ for descending order on that field. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--uri

Print a list of resource URIs instead of the default output, and change the command output to a list of URIs. If this flag is used with --format, the formatting is applied on this URI list. To display URIs alongside other keys instead, use the uri() transform.
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:
