Project Overview

This project demonstrates how to deploy a WordPress application on AWS using Terraform and CI/CD Pipeline. The infrastructure includes:

• EC2 Instance: Hosts the WordPress application with PHP 8.x and Apache.
• RDS MySQL Database: Stores WordPress data.
• VPC, Subnets, and Security Groups: Secure and isolate the resources.
• Auto-Assign Public IP: Ensures the EC2 instance is accessible over the internet.

Features

• Infrastructure as Code: Automated provisioning using Terraform.
• Scalable WordPress Deployment: EC2 instance with PHP 8.x and Apache.
• Secure Database: RDS MySQL database with multi-AZ support.
• Public Access: Auto-assign public IP for the EC2 instance.

Prerequisites

1. AWS Account: Ensure you have an AWS account with sufficient permissions.
2. Terraform Installed: Download and install Terraform from here.
3. AWS CLI Installed: Install the AWS CLI and configure it with aws configure.
4. SSH Key Pair: Create an SSH key pair in AWS or use an existing one.

CI/CD Pipeline

This project includes a GitHub Actions workflow to automate Terraform validation and deployment. The pipeline performs the following steps:

1. Terraform Init: Initializes the Terraform configuration.
2. Terraform Validate: Validates the Terraform configuration.
3. Terraform Plan: Generates an execution plan.
4. Terraform Apply: Applies the Terraform configuration (only on the main branch).

To use the pipeline:

1. Add your AWS credentials as GitHub Secrets (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY).
2. Push changes to the main branch to trigger the pipeline.

Steps to Deploy

1. Clone this repository:

   git clone https://github.com/abaasi256/terraform-wordpress-deployment.git
   cd terraform-wordpress-deployment

2. Update the terraform.tfvars file with your AWS credentials and configuration:

   aws_region = "us-east-1"
   ami_id = "ami-0c02fb55956c7d316"  # Replace with a valid AMI ID for your region
   instance_type = "t2.micro"
   key_name = "your-key-pair-name"
   db_name = "wordpressdb"
   db_user = "admin"
   db_password = "your-strong-password"
   availability_zone = "us-east-1a"

3. Initialize and apply the Terraform configuration:

   terraform init
   terraform plan
   terraform apply

4. Access the WordPress application:
   • Open a web browser and navigate to:

     http://<EC2-Public-IP>
     

   • Complete the WordPress installation wizard.
