Terraform - First VM at Google cloud

Download Terraform:  Terraforms
Download GCP Cli SDK:   Google Cloud SDK
Download Code Editor:   Visual Studio

Pre requirements

FIrst you will need to setting Up GCP account, create a API credentials from gcloud console (APIs & Services / Credentials). After that you are ready do configure your terraform script to Plan, Apply and Destroy an GCP Virtual Machine.

Plan, Apply and Destroy GCP Virtual Machine using Terraform

This example ilustrates commands used by Ubuntu. After installing terraform and gcp cloud SDK you will need:
- GCP Service account key (Json file)
- GCP Project ID
- Define GCP  Region & Zones and set your default Region/zone for your project.

Save your secret key (secrets.json) locally, this will be set as a variable in our script. In this scenario I used:

/home/andrehps/terraform/credentials

Folder structure is like this:

  	/home/andrehps/terraform 

  	~/terraform/credentials 

  	~/terraform/first_instance 

  

File location: ~/terraform/first_instance:

  	- main.tf 

  	- provider.tf 

  

Terraform scripts

provider.tf

variable "path" {default = "/home/andrehps/terraform/credentials"}


provider "google" {
    project = "celfocus-vfpt-poc-dwh"
    region = "europe-west1-b"
    credentials = "${file("${var.path}/secrets-VFPTPOC.json")}"
}
	

main.tf

resource "google_compute_instance" "default" {
name = "firstvm"
machine_type = "n1-standard-1"
zone = "europe-west1-b"
  
  boot_disk {
      initialize_params {
          image = "ubuntu-os-cloud/ubuntu-1604-lts"
      }
  }
  network_interface {
      network = "default"
  }
  service_account{
      scopes = ["userinfo-email","compute-ro","storage-ro"]
  }
}
	

To execute terraform commands from anyware, you need to set up your path variable:

export PATH:$PATH:/opt
