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

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

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

        $ gcloud 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.
