Terraform module which creates a google cloud subnetwork with options for secondary CIDR ranges.
- You want to create a set of subnetworks around an GCP Network.
- You've already created a bunch of subnetworks with distinct configurations (with and without secondary ranges) and want to centralize it in only one module
With Secondary CIDR Range
module "aliased-subnetwork" {
source = "./modules/subnetwork"
name = "aliased-subnet"
network = "${google_compute_network.network.self_link}"
ip_cidr_range = "10.100.0.0/24"
create_secondary_ranges = true
secondary_ranges = [
{
range_name = "range-1"
ip_cidr_range = "10.101.0.0/24"
},
{
range_name = "range-2"
ip_cidr_range = "10.102.0.0/24"
},
]
}Without Secondary CIDR Range
module "basic-subnetwork" {
source = "./modules/subnetwork"
name = "basic-subnet"
description = "Basic subnet"
network = "${google_compute_network.network.self_link}"
ip_cidr_range = "10.100.0.0/24"
}Then perform the following commands on the root folder:
