Google Compute Engine External VPN Gateway
This page shows how to write Terraform for Compute Engine External VPN Gateway and write them securely.
google_compute_external_vpn_gateway (Terraform)
The External VPN Gateway in Compute Engine can be configured in Terraform with the resource name google_compute_external_vpn_gateway
. The following sections describe 2 examples of how to use the resource and its parameters.
Example Usage from GitHub
resource "google_compute_external_vpn_gateway" "my_compute_external_vpn_gateway" {
name = "my_compute_external_vpn_gateway"
redundancy_type = "SINGLE_IP_INTERNALLY_REDUNDANT"
description = "An externally managed VPN gateway"
interface {
id = 0
resource "google_compute_external_vpn_gateway" "my_compute_external_vpn_gateway" {
name = "my_compute_external_vpn_gateway"
redundancy_type = "SINGLE_IP_INTERNALLY_REDUNDANT"
description = "An externally managed VPN gateway"
interface {
id = 0
Parameters
-
description
optional - string
An optional description of this resource.
Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression 'a-z?' which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

project
optional computed - string -
redundancy_type
optional - string
Indicates the redundancy type of this external VPN gateway Possible values: ["FOUR_IPS_REDUNDANCY", "SINGLE_IP_INTERNALLY_REDUNDANT", "TWO_IPS_REDUNDANCY"]
-
self_link
optional computed - string -
interface
list block-
id
optional - number
The numeric ID for this interface. Allowed values are based on the redundancy type of this external VPN gateway '0 - SINGLE_IP_INTERNALLY_REDUNDANT' '0, 1 - TWO_IPS_REDUNDANCY' * '0, 1, 2, 3 - FOUR_IPS_REDUNDANCY'
-
ip_address
optional - string
IP address of the interface in the external VPN gateway. Only IPv4 is supported. This IP address can be either from your on-premise gateway or another Cloud provider's VPN gateway, it cannot be an IP address from Google Compute Engine.

Tips: Best Practices for The Other Google Compute Engine Resources
In addition to the google_compute_disk, Google Compute Engine has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
google_compute_disk
Ensure the encryption key for your GCE disk is stored securely
It is better to store the encryption key for your GCE disk securely. Secret Manager could be used instead.
google_compute_firewall
Ensure your VPC firewall blocks unwanted outbound traffic
It is better to block unwanted outbound traffic not to expose resources in the VPC to unwanted attacks.
google_compute_instance
Ensure appropriate service account is assigned to your GCE instance
It is better to create a custom service account for the instance and assign it.
google_compute_project_metadata
Ensure OS login for your GCE instances is enabled at project level
It is better to enable OS login for your GCE instances. Enabling OS login ensures that SSH keys used to connect to instances are mapped with IAM users, allowing centralized and automated SSH key management.
google_compute_ssl_policy
Ensure to use modern TLS protocols
It's better to adopt TLS v1.2+ instead of outdated TLS protocols.
google_compute_subnetwork
Ensure VPC flow logging is enabled
It is better to enable VPC flow logging. VPC flow logging allows us to audit traffic in your network.
