gcloud compute networks subnets expand-ip-range

NAME
gcloud compute networks subnets expand-ip-range - expand the IP range of a Compute Engine subnetwork
SYNOPSIS
gcloud compute networks subnets expand-ip-range NAME --prefix-length=PREFIX_LENGTH [--region=REGION] [GCLOUD_WIDE_FLAG]
DESCRIPTION
gcloud compute networks subnets expand-ip-range expands the IP range of a VPC subnetwork.

For more information about expanding a subnet, see Expanding a primary IP range.

This command doesn't work for secondary subnets or for subnets that are used exclusively for load balancer proxies. For more information, see Proxy-only subnets for load balancers.

EXAMPLES
To expand the IP range of SUBNET to /16, run:
gcloud compute networks subnets expand-ip-range SUBNET --region=us-central1 --prefix-length=16
POSITIONAL ARGUMENTS
NAME
Name of the subnetwork to operate on.
REQUIRED FLAGS
--prefix-length=PREFIX_LENGTH
The new prefix length of the subnet. It must be smaller than the original and in the private address space 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16 defined in RFC 1918.
OPTIONAL FLAGS
--region=REGION
Region of the subnetwork to operate on. If not specified, you might be prompted to select a region (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/region property:

gcloud config set compute/region REGION

A list of regions can be fetched by running:

gcloud compute regions list

To unset the property, run:

gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable CLOUDSDK_COMPUTE_REGION.

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.
