terraform-azure-vnet

This module creates the basic and advance network resources for a region.

Prerequisites

Name	Version
terraform	>= 1.3.0

Before you begin, ensure you have the following installed:

• Terraform (version X.XX.X)
• Azure CLI (version X.XX.X)
• Azure Subscription

Getting Started

Follow the steps below to get started with the project:

1. Clone this repository to your local machine.
2. Authenticate the Azure CLI with your Azure Subscription using az login.
3. Initialize Terraform by running terraform init.
4. If you want to create VNet with advanced subnet settings (enable natgateway , user defined security rule per subnet) etc.. then choose the vnet-advance module in example module.

Variables

The project uses the following variables:

• location: The Azure region where resources will be created.
• resource_group_name: The name of the resource group where resources will be provisioned.
• vnet_name: The name of the Virtual Network.
• subnet_type: The type of subnets to create.
• subnet_bits: The number of simple subnets to create (used when subnet_type = "subnet-simple").

Usage

To provision the resources, modify the variables in variables.tf to match your desired configuration. Then, run the following Terraform commands:

1. terraform init: Initializes the Terraform configuration.
2. terraform plan: Shows the execution plan for the resources.
3. terraform apply: Applies the changes and creates the Azure resources.
