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

    For more information regarding permissions required by instance groups,
    refer to Compute Engine's access control guide:
    https://cloud.google.com/compute/docs/access/iam.

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:

        $ gcloud compute instance-groups list-instances

        $ gcloud beta compute instance-groups list-instances
