Instance Group Manager Terraform Module

This Terraform module creates a managed instance group in Google Cloud Platform, based on a instance template.

Usage

You can use this module by referencing it in your Terraform code:

module "instance_group_manager" {
  source  = "git@github.com:Retize-io/terraform_gce_instance_group.git?ref=v1.0.0"

  group_name                          = "my-group"
  target_size                         = 2
  version_name                        = "my-version"
  template_id                         = "my-template-id"
  zone                                = "us-central1-a"
  min_replicas                        = 1
  max_replicas                        = 3
  named_port                          = 80
  target_load_balancing_utilization   = 0.9
  target_cpu_utilization              = 0.9
  cooldown_period                     = 150
}

Make sure to replace the values with your own group name, target size, version name, template ID, zone, minimum replicas, maximum replicas, named port, target load balancing utilization, target CPU utilization, and cooldown period.
