Introduction
This guide walks you through the step-by-step process of provisioning Azure resources using Terraform, deploying a virtual machine, retrieving its IP, connecting via SSH, and finally destroying the VM. We'll use VS Code to edit our Terraform scripts for a smooth development experience.
Prerequisites
Before we begin, ensure you have the following installed on your machine:
Terraform (Download here)
Azure CLI (Download here)
VS Code (Download here)- An active Azure subscription
Installing and Configuring Terraform
First, verify that Terraform is installed by running:
terraform -v
If Terraform is not installed, download and install it from Terraform's official site.
Log in to Azure with:
az login
Set your default subscription (replace your-sub-id with your actual subscription ID):
az account set --subscription your-sub-id
Setting Up Your Terraform Project in VS Code
- Open VS Code
Create a new folder (e.g.,azure-terraform-vm)- Open the folder in VS Code
Create a new file namedmain.tf
Writing the Terraform Configuration
Copy the following Terraform code into main.tf. Replace your-VM-name, your-Vnet-name, etc., with meaningful names of your choice. Don't forget to replace the username and password as well, that's what you will use to SSH into your VM

}
}
output "public_ip_address" {
description = "The public IP address of the virtual machine"
value = azurerm_public_ip.your-ip-name.ip_address
}
Initializing and Applying the Terraform Configuration
Run the following commands in the terminal inside VS Code:
terraform init
terraform plan
terraform apply -auto-approve
Terraform will create all the specified resources in Azure.
Retrieving the VM's Public IP and Connecting via SSH
Get the public IP:
echo $(terraform output -raw public_ip_address)
Use SSH to connect to the VM:
ssh your-admin-username@your-vm-public-ip
Destroying the VM
Once you're done, destroy the VM to avoid unnecessary charges:
terraform destroy -auto-approve
Conclusion
Congratulations! 🎉 You've successfully:
- Provisioned Azure resources using Terraform
- Deployed a Virtual Machine
- Retrieved its IP and connected via SSH
- Cleaned up resources by destroying the VM
This is just the beginning of your Terraform journey in Azure! 🚀 Stay tuned for more DevOps guides.
