Creating VM Cluster on Azure #Cloud with Terraform #IaC #Azure #Terraform #Linux #Winserv

Type az and you should see this Azure CLI

Type Terraform and you should see the terraform commands

Install and configure Terraform to provision VMs and other infrastructure into Azure

Before you begin with Terraform and deploying your solution to Microsoft Azure you have to install Azure CLI and Terraform for your OS.

In the following step-by-step guide we will deploy a VM Cluster with Terraform into Microsoft Azure Cloud Services.

First we open Powershell in Administrator mode :

You should have your Terraform script ready.

It’s great to edit your Terraform script in Visual Studio Code

Create a Terraform configuration file
In this section, you create a file that contains resource definitions for your infrastructure.
Create a new file named main.tf.
Copy following sample resource definitions into the newly created main.tf file:

resource “azurerm_resource_group” “test” {
name = “acctestrg”
