- NAME
-
- gcloud beta compute networks subnets expand-ip-range - expand the IP range of a Compute Engine subnetwork
- SYNOPSIS
-
-
gcloud beta compute networks subnets expand-ip-rangeNAME--prefix-length=PREFIX_LENGTH[--region=REGION] [GCLOUD_WIDE_FLAG …]
-
- DESCRIPTION
-
(BETA)gcloud beta compute networks subnets expand-ip-rangeexpands 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
to /16, run:SUBNETgcloud beta 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
property:compute/regiongcloud config set compute/region REGIONA list of regions can be fetched by running:
gcloud compute regions listTo unset the property, run:
gcloud config unset compute/regionAlternatively, the region can be stored in the environment variable
.CLOUDSDK_COMPUTE_REGION
