This project demonstrates how to create and manage infrastructure using Terraform and automate the deployment process using GitHub Actions as CI/CD.

• Introduction
• Terraform Modules
• AWS S3 Remote Backend
• GitHub Actions Workflow
• Getting Started
• Usage

This repository provides a modular approach to creating AWS resources such as:

• Application Load Balancer
• Security Groups
• EC2 Instances
• VPC

The deployment process is fully automated using GitHub Actions, triggered on every push to the main branch.

• VPC Module: Creates a Virtual Private Cloud.
• Security Groups Module: Manages security groups.
• EC2 Module: Provisions EC2 instances.
• Application Load Balancer Module: Sets up an ALB.

We use AWS S3 to store the Terraform state files remotely, enabling team collaboration and state locking.

The GitHub Actions workflow is defined in .github/workflows/deploy.yml and includes the following steps:

1. Checkout Code: Checks out the repository code.
2. Set up Terraform: Installs Terraform.
3. Initialize Terraform: Initializes Terraform configuration.
4. Validate Terraform: Validates the Terraform configuration.
5. Apply Terraform: Applies the Terraform configuration to provision resources.
6. Destroy Terraform: Destroys the infrastructure (commented out).

Prerequisites

1. Terraform installed
2. AWS CLI configured with appropriate credentials
3. GitHub repository with Secrets for AWS credentials
4. Installation

• Clone the repository:

git clone https://github.com/parvez76/terraform-with-github-actions

cd iaac

terraform init

Deploy Infrastructure: Push your changes to the main branch to trigger the GitHub Actions workflow:

git add .

git commit -m "Deploy infrastructure"

git push origin main

Destroy Infrastructure: To destroy the infrastructure, uncomment the Terraform Apply section in the workflow and comment out the Terraform Destroy section, then push the changes.
