gcloud beta compute networks subnets expand-ip-range - expand the IP range of a Compute Engine subnetwork
gcloud beta compute networks subnets expand-ip-range NAME --prefix-length=PREFIX_LENGTH [--region=REGION] [GCLOUD_WIDE_FLAG ...]
(BETA) gcloud beta 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 https://cloud.google.com/vpc/docs/using-vpc#expand-subnet.
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 https://cloud.google.com/load-balancing/docs/l7-internal/proxy-only-subnets.
To expand the IP range of SUBNET to /16, run:
$ gcloud beta compute networks subnets expand-ip-range SUBNET \ --region=us-central1 --prefix-length=16
- NAME
Name of the subnetwork to operate on.
- --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.
- --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.
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.
This command is currently in beta and might change without notice. These variants are also available:
