Unable to boot the RDS inside a VPC in GCP - postgresql

Question

I need to boot the RDS of Postgres inside a VPC. I need the code of Google Provider.
I have Tried official terraform.io and also github https://github.com/GoogleCloudPlatform/terraform-google-sql-db/blob/227b1ec7a830622560bff85194a816638be1c7c5/examples/mysql-and-postgres/main.tf#L82 but didnt have any luck
name = "name"
project = "project_name"
region = "us-east-1"
database_version = "${var.database_version}"
settings {
tier = "${var.machine_type}"
ip_configuration {
ipv4_enabled = true
authorized_networks = {
name = "${data.terraform_remote_state.vpc.outputs.network_name}"
value = "10.10.22.0/24"
}
}
i had also tried
ip_configuration = [{
private_network = "${var.network_cird_range}"
}]
"I expect the RDS to be boot inside a VPC , but i couldn't find any luck. can anyone help me out here
Thanks in Advance

If I understood your issue correctly, you are getting an error while creating a Google Cloud SQL instance with Private IP using Terraform, am I right? if so, here is my code to achieve what you want:
provider "google" {
credentials = "${file("CREDENTIALS.json")}"
project = "PROJECT-ID"
region = "us-central1"
}
resource "google_compute_network" "private_network" {
name = "testnw"
}
resource "google_compute_global_address" "private_ip_address" {
provider="google"
name = "${google_compute_network.private_network.name}"
purpose = "VPC_PEERING"
address_type = "INTERNAL"
prefix_length = 16
network = "${google_compute_network.private_network.name}"
}
resource "google_service_networking_connection" "private_vpc_connection" {
provider="google"
network = "${google_compute_network.private_network.self_link}"
service = "servicenetworking.googleapis.com"
reserved_peering_ranges = ["${google_compute_global_address.private_ip_address.name}"]
}
resource "google_sql_database_instance" "instance" {
provider="google"
depends_on = ["google_service_networking_connection.private_vpc_connection"]
name = "privateinstance"
region = "us-central1"
settings {
tier = "db-f1-micro"
ip_configuration {
ipv4_enabled = "false"
private_network = "projects/PROJECT-ID/global/networks/${google_compute_network.private_network.name}"
}
}
}
This code will create a VPC NW, then will allocate an IP range automatically, then will create a "service networking peering", and after that, a Cloud SQL instance with private IP.

I had faced the same issue when I tried to use Google Terraform Module to create a PostgreSQL managed instance. In my case, I'm fixing that using this:
private_network = "projects/PROJECT_ID/global/networks/NETWORK_NAME"
Try this and let me know if it solves your problem.
