Azure Infrastructure Project

Overview

This project provisions a scalable, secure, and reusable Azure infrastructure using Terraform. It consists of several modules to manage key Azure resources. The goal is to make the infrastructure easily deployable and customizable for multiple clients.

Purpose of Each Module

1. Network Module

  • Provisions an Azure Virtual Network (VNET), Subnet, and associates a Network Security Group (NSG) to protect the network traffic.
  • Resources Created:
    • Virtual Network
    • Subnet
    • Network Security Group (NSG)

2. Storage Account Module

  • Creates an Azure Storage Account and an associated container.
  • Resources Created:
    • Storage Account
    • Storage Container

3. Virtual Machine Module

  • Provisions an Azure Linux Virtual Machine and connects it to the VNET.
  • Resources Created:
    • Linux Virtual Machine
    • Network Interface (NIC)
    • VM Disk

4. Key Vault Module

  • Provisions an Azure Key Vault and stores sensitive secrets, including the Virtual Machine credentials and Storage Account Access Keys.
  • Resources Created:
    • Azure Key Vault
    • Key Vault Secrets (VM credentials, Storage Account Access Key)

Pre-requisites

Before using this Terraform configuration, ensure you have the following:

  1. Azure Subscription: You need a valid Azure subscription to provision resources.
  2. Azure CLI: Install the Azure CLI and ensure you are authenticated using:
az login
  1. Terraform CLI: Install the Terraform CLI
  2. Service Principal (Optional): If automating, create an Azure service principal and configure it in your environment:
az ad sp create-for-rbac --name terraform --role Contributor

How to use the Terraform scripts

  1. Configure Variables: Create/Edit the terraform.tfvars file with your specific values.
  2. Initialize Terraform: Run the following command to initialize the working directory that contains the configuration files:
terraform init
  1. Plan the Infrastructure: Use the terraform plan command to preview the infrastructure changes and verify if the configuration is correct:
terraform plan -out="main.tfplan"
  1. Apply the Changes: Once you're satisfied with the plan, apply the changes to create the resources in Azure:
terraform apply "main.tfplan"
  1. Destroy the Infrastructure: If you want to tear down the infrastructure created by this configuration, use the following command:
terraform destroy
