Terraform on google cloud

[usman317]

I am trying to create resources and services on google cloud using terraform. following up this guide

https://cloud.google.com/docs/terraform/get-started-with-terraform

In this guide we create a vpc network and then a subnet and then the vm.

Then we can attach the vm to the subnet we created. But suppose that I don't want to create a new vpc network instead I want to attach the vm with the default network which is already present. I have to change this parameter

network_interface {
	subnetwork = google_compute_subnetwork.default.id
	access_config {
	# Include this section to give the VM an external IP address
	}
}

How would I do it? What should I provide in subnetwork = google_compute_subnetwork.***********
