Terraform GCP provider setup - Mini Project: Build & Apply

Terraform GCP provider setup

📖 Scenario: You are starting a new cloud project on Google Cloud Platform (GCP). To manage your cloud resources efficiently, you want to use Terraform, a tool that helps you write code to create and manage cloud infrastructure.Before you can create any resources, you need to set up Terraform to connect to your GCP account properly.

🎯 Goal: Set up Terraform configuration to use the GCP provider with the correct project and region settings.

📋 What You'll Learn

Create a Terraform configuration file named main.tf.

Configure the GCP provider with the exact project ID my-gcp-project-123.

Set the region to us-central1.

Specify the provider version as 4.0.0.

Add a variable for the project ID with a default value.

💡 Why This Matters

🌍 Real World

Terraform is widely used to manage cloud infrastructure as code. Setting up the provider correctly is the first step to automate resource creation and management on GCP.

💼 Career

Cloud engineers and DevOps professionals must know how to configure Terraform providers to work with cloud platforms like GCP for efficient infrastructure automation.

1

Create Terraform configuration file with provider block

Create a file named main.tf and write a terraform block with required providers specifying google = { source = "hashicorp/google", version = "4.0.0" }. Then add a provider block for google with project = "my-gcp-project-123" and region = "us-central1".

GCP

# Your code here to create terraform and provider blocks

Need a hint?

Start by defining the terraform block with required_providers. Then add the provider "google" block with the project and region.

2

Add a variable for the project ID

Add a Terraform variable block named project_id with a default value set to "my-gcp-project-123".

GCP

terraform {
  required_providers {
    google = {
      source  = "hashicorp/google"
      version = "4.0.0"
    }
  }
}

provider "google" {
  project = "my-gcp-project-123"
  region  = "us-central1"
}

# Your code here to add variable block

Need a hint?

Use the variable keyword followed by the variable name and set the default value inside curly braces.

3

Use the variable in the provider block

Modify the provider "google" block to use the variable project_id for the project attribute by setting project = var.project_id.

GCP

terraform {
  required_providers {
    google = {
      source  = "hashicorp/google"
      version = "4.0.0"
    }
  }
}

provider "google" {
  project = "my-gcp-project-123"
  region  = "us-central1"
}

variable "project_id" {
  default = "my-gcp-project-123"
}

# Your code here to update provider project to use var.project_id

Need a hint?

Replace the fixed project string with var.project_id inside the provider block.

4

Add a backend configuration for remote state

Add a terraform backend block inside the existing terraform block to configure remote state storage using gcs with bucket = "my-terraform-state-bucket" and prefix = "terraform/state".

GCP

terraform {
  required_providers {
    google = {
      source  = "hashicorp/google"
      version = "4.0.0"
    }
  }

  # Your code here to add backend block
}

provider "google" {
  project = var.project_id
  region  = "us-central1"
}

variable "project_id" {
  default = "my-gcp-project-123"
}

Need a hint?

Inside the terraform block, add a backend "gcs" block with the bucket and prefix settings.
