Review Project

Let’s explore the generated app folder.

App Modules

Let’s check out the app/modules/example folder.

resource "google_storage_bucket" "this" {
  name                        =
  uniform_bucket_level_access = var.uniform_bucket_level_access

variable "name" {
  description = "bucket name (required)"
  type        = string

variable "uniform_bucket_level_access" {
  description = "uniform_bucket_level_access"
  type        = bool
  default     = false

You can see that the starter example module creates an gcs bucket.

Stack Modules

Next let’s look at the generated app/stacks/demo that was created:


resource "random_pet" "this" {
  length = 2

module "bucket" {
  source = "../../modules/example"

  name                        = "bucket-${}"
  uniform_bucket_level_access = var.uniform_bucket_level_access

You can see that it’s just another terraform module, that will use the app/modules/example module. It uses the random_pet resource to provide a random but friendly name for the gcs bucket.

Modules vs Stacks

Both modules and stacks are terraform modules. The difference is organizational and how they are meant to be used.

For example, the app1 stack could be designed to use the instance module. Another, app2 stack could use the instance and rds modules.

Next, we’ll deploy the infrastructure.
