Terraform Project Documentation

Overview

This project uses Terraform to manage infrastructure as code (IaC). It defines, provisions, and maintains resources in the desired cloud environment, ensuring consistency and scalability.

Features

• Deploys a Virtual Network with subnets.
• Provisions compute resources (e.g., Virtual Machines or Containers).
• Configures storage and networking components.

Prerequisites

To use this project, ensure you have the following installed:

• Terraform (>= 1.0.0)
• Cloud provider CLI (e.g., az for Azure, aws for AWS)
• Access to the cloud provider account with necessary permissions
• Git

Optional Tools

• Terragrunt for managing Terraform configurations across multiple environments.
• tflint for static code analysis.

Getting Started

Step 1: Clone the Repository

git clone <repository-url>
cd terraform-project

Step 2: Configure Backend

Update the backend.tf file with your backend configuration (e.g., S3, Azure Blob Storage, etc.).

Step 3: Initialize Terraform

Run the following command to initialize the project:

terraform init

Step 4: Validate Configuration

Ensure that the configuration is correct:

terraform validate

Step 5: Plan Infrastructure

Review the changes Terraform will make to the infrastructure:

terraform plan -var-file=environments/dev/terraform.tfvars

Step 6: Apply Changes

Deploy the infrastructure:

terraform apply -var-file=environments/dev/terraform.tfvars

Step 7: Destroy Infrastructure

To remove all resources, use:

terraform destroy -var-file=environments/dev/terraform.tfvars

Inputs

Name	Description	Type	Default	Required
region	Cloud region to deploy resources	string	us-east	yes
environment	Deployment environment (e.g., dev, prod)	string	N/A	yes

Outputs

Name	Description
vnet_id	ID of the created Virtual Network
vm_public_ip	Public IP of the Virtual Machine

Best Practices

• Use version control for your Terraform configurations.
• Enable remote state storage and state locking.
• Use workspaces or separate configurations for managing multiple environments.
• Review the execution plan (terraform plan) before applying changes.

Troubleshooting

• Ensure you have the necessary permissions to provision resources.
• Check provider configuration in providers.tf.
• Validate the syntax and configuration files with:

  terraform fmt -check
  terraform validate
