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: 

gcloudconfigsetcompute/zoneZONE

A list of zones can be fetched by running: 

gcloudcomputezoneslist

To unset the property, run: 

gcloudconfigunsetcompute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.
