Google Compute Engine Instance Group Named Port

This page shows how to write Terraform for Compute Engine Instance Group Named Port and write them securely.

google_compute_instance_group_named_port (Terraform)

The Instance Group Named Port in Compute Engine can be configured in Terraform with the resource name google_compute_instance_group_named_port. The following sections describe 5 examples of how to use the resource and its parameters.

Example Usage from GitHub

main.tf#L26
resource "google_compute_instance_group_named_port" "named_port_0" {
  group = google_container_cluster.gke_cluster.instance_group_urls[0]
  name  = "http"
  port  = 30000
}

named-port.tf#L1
resource "google_compute_instance_group_named_port" "http_port" {
  group = google_compute_instance_group_manager.jack_manager.name
  zone = data.google_compute_zones.available.names.0

  name = "http"
  port = 80
named-port.tf#L1
resource "google_compute_instance_group_named_port" "http_port" {
  group = google_compute_instance_group_manager.jack_manager.name
  zone = data.google_compute_zones.available.names.0

  name = "http"
  port = 80
main.tf#L39
resource "google_compute_instance_group_named_port" "http" {
  for_each = data.google_compute_instance_group.instance_groups
  group    = each.value.self_link
  zone     = each.value.zone
  name     = "http"
  port     = 80
main.tf#L7
resource "google_compute_instance_group_named_port" "this" {
  group   = var.group
  name    = var.name
  port    = var.port
  project = var.project
  zone    = var.zone

Review your Terraform file for Google best practices

Shisho Cloud, our free checker to make sure your Terraform configuration follows best practices, is available (beta).

Parameters

The name of the instance group.

  • id optional computed - string
  • name required - string

The name for this named port. The name must be 1-63 characters long, and comply with RFC1035.

The port number, which can be a value between 1 and 65535.

  • project optional computed - string
  • zone optional computed - string

The zone of the instance group.

Explanation in Terraform Registry

Mange the named ports setting for a managed instance group without managing the group as whole. This resource is primarily intended for use with GKE-generated groups that shouldn't otherwise be managed by other tools. To get more information about InstanceGroupNamedPort, see:

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.

risk-label

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.

risk-label

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.

risk-label

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.

risk-label

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.

risk-label

google_compute_ssl_policy

Ensure to use modern TLS protocols

It's better to adopt TLS v1.2+ instead of outdated TLS protocols.

risk-label

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.

Review your Google Compute Engine settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
