The above example lists named ports assigned to an instance group named'example-instance-group' in theus-central1-a zone.

NAME

Name of the instance group to operate on.

At most one of these can be specified:

--region=REGION

Region of the instance group to operate on. If not specified, you might beprompted to select a region (interactive mode only).

A list of regions can be fetched by running:

gcloudcomputeregionslist

Overrides the defaultcompute/region property value for thiscommand invocation.

--zone=ZONE

Zone of the instance group to operate on. If not specified, you might beprompted to select a zone (interactive mode only).

A list of zones can be fetched by running:

gcloudcomputezoneslist

Overrides the defaultcompute/zone property value for this commandinvocation.

--filter=EXPRESSION

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

--limit=LIMIT

Maximum number of resources to list. The default isunlimited. Thisflag 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 themaximum number of resources per page. The default is determined by the serviceif it supports paging, otherwise it isunlimited (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 orderis ascending. Prefix a field with ``~´´ for descending order on thatfield. 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 thecommand output to a list of URIs. If this flag is used with--format, the formatting is applied on this URI list. To displayURIs alongside other keys instead, use theuri() transform.
