Using Terraform to create a VM

Infrastructure As A Service GCP

Introduction

This project is a simple example of how to use Terraform to create a GCP project and a GCP instance. I will use VSCode to write the code and run the Terraform commands on a Windows machine.

Prerequisites

Create a GCP project

  • Create a GCP project

  • Create a new repository on GitHub and clone it to your local machine

  • Open the project on VSCode and create a new folder called "terraform"

  • Open a terminal on VSCode or other terminal window and change into the terraform folder directory

  • Run the following command to initialize the terraform project terraform init

  • Create a new file called "main.tf" and add the following code:

    provider "google" {
# Path to GCP service account credentials
credentials = file("Path to GCP service account credentials")
# Your GCP project ID
project = "your-project-id"
# Any region of your choice
region = "your preferred region"
# Any zone of your choice
zone = "your preferred zone"
}

    resource "google_compute_instance" "vm" {
name         = "iaas-vm"
machine_type = "e2-micro"
zone         = "us-east4-b"

boot_disk {
initialize_params {
  image = "ubuntu-os-cloud/ubuntu-2004-lts"
}
}

network_interface {
network = "default"
access_config {
  // Ephemeral IP
}
}

  • In the terminal, run terraform fmt to format the code in the tf files

  • Run terraform init again to initialize the project

  • Run terraform plan to see what will be created

  • Run terraform apply to create the VM on GCP

After this step you will have a GCP project and a VM created. You should be able to see a VM in the console named iaas-vm under Compute Engine.

Once you are done with the project you can run the following command to destroy the resources so you don't incur more charges: terraform destroy
