NAME
    gcloud alpha compute instance-groups unmanaged add-instances - adds
        instances to an unmanaged instance group by name

SYNOPSIS
    gcloud alpha compute instance-groups unmanaged add-instances NAME
        --instances=INSTANCE,[INSTANCE,...] [--zone=ZONE]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) gcloud alpha compute instance-groups unmanaged add-instances adds
    existing instances to an unmanaged instance group by name. For example:

        $ gcloud alpha compute instance-groups unmanaged add-instances \
            my-group \
            --instances my-instance-1,my-instance-2 --zone us-central1-a

POSITIONAL ARGUMENTS
     NAME
        Name of the instance group to operate on.

REQUIRED FLAGS
     --instances=INSTANCE,[INSTANCE,...]
        A list of names of instances to add to the instance group. These must
        exist beforehand and must live in the same zone as the instance group.

OPTIONAL FLAGS
     --zone=ZONE
        Zone of the instance group to operate on. 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:

        $ gcloud compute instance-groups unmanaged add-instances

        $ gcloud beta compute instance-groups unmanaged add-instances
