How to create subnets in GCP cloud using Terraform

Question

Hi Guys,

I have created a network in the GCP cloud. Now I want to create a subnet in this network using Terraform. How can I do that?

Hi@akhtar,

You need to create a network first. A subnet is always a part of a network. So before subnet, you have to create one network as shown below.

resource "google_compute_subnetwork" "network-for-l7lb" {
  provider = google-beta
  name          = "l7lb-test-subnetwork"
  ip_cidr_range = "10.0.0.0/24"
  region        = "us-central1"
  purpose       = "INTERNAL_HTTPS_LOAD_BALANCER"
  role          = "ACTIVE"
  network       = google_compute_network.custom-test.id
}
resource "google_compute_network" "custom-test" {
  provider = google-beta
  name                    = "l7lb-test-network"
  auto_create_subnetworks = false
}

Hope this helps!!

If you need to know more about Google Cloud, It's recommended to go for Google Cloud architect certification course.
