Check Terraform Installation

terraform --version

touch main.tf

• main.tf

terraform {
  required_providers {
    google = {
      source = "hashicorp/google"
    }
  }
}
provider "google" {
  region  = "us-central1"
  zone    = "us-central1-c"
}

terraform init

• Add the following to main.tf

resource "google_compute_instance" "terraform" {
  name         = "terraform"
  machine_type = "n1-standard-2"
  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-11"
    }
  }
}

terraform plan
## The configuration fails with the following error. This is because you cannot configure a compute engine without a network.

• Now add the network by including the following code segment to the google_compute_instance block.

network_interface {
    network = "default"
    access_config {
    }
}

terraform plan

terraform apply

• Validate on console

Change the infrastructure

• Add a tags argument to the instance we just created so that it looks like this:

resource "google_compute_instance" "terraform" {
  name         = "terraform"
  machine_type = "n1-standard-2"
  tags         = ["web", "dev"]
  # ...
}

terraform plan

terraform apply

• Edit machine type

resource "google_compute_instance" "terraform" {
  name         = "terraform"
  machine_type = "n1-standard-1"
  tags         = ["web", "dev"]
  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-11"
    }
  }
  network_interface {
    network = "default"
    access_config {
    }
  }
  allow_stopping_for_update = true
}

Destroy the Infrastructure
