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”
location = “West US 2”
}
resource “azurerm_virtual_network” “test” {
name = “acctvn”
address_space = [“10.0.0.0/16”]
location = “${azurerm_resource_group.test.location}”
resource_group_name = “${azurerm_resource_group.test.name}”
}

Type : terraform init
You should see this screen.
Type : az login
We now logging into Microsoft Azure subscription.
https://microsoft.com/devicelogin
Insert the code from your Powershell screen.
Now we have the Terraform INIT running and we are connected to our Azure Subscription 😉
Type : terraform plan
It will refreshing the state and getting ready for deployment.
Type : terraform apply
and then type : yes <enter>
Terraform is now creating the azure resources
Azure resource group acctestrg is made
Terraform deployment VM Cluster on Azure is Ready 😉
Azure VM Cluster is running.
When you want to remove the complete Azure VM Cluster with terraform, it’s really easy :
Type : terraform destroy
and then type : yes <enter>
Azure resources are being deleted via terraform script
Terraform destroyed the Azure VM Cluster
All Azure Resources of the VM Cluster are removed.
Hope this step-by-step guide deploying infrastructure as Code with terraform will help you with your own Cloud solutions in Microsoft azure.
Ps. don’t forget to install Visual Studio Code Azure Terraform extension and play !
