Terraform AWS Infrastructure Deployment

This project demonstrates how to use Terraform to provision and manage AWS resources, including:

• VPC: Virtual Private Cloud with subnets, internet gateway, and route tables.
• S3 Bucket: Secure S3 bucket with a bucket policy to enforce HTTPS access.
• RDS Instance: MySQL database instance with a security group and subnet group across multiple AZs.
• GitHub Actions: Automated Terraform workflow for CI/CD.

Project Overview

This Terraform project automates the deployment of a secure and scalable AWS infrastructure, including:

• VPC: A Virtual Private Cloud with public subnets.
• Subnets: Two public subnets across different availability zones.
• Internet Gateway: Enables internet access for resources in the public subnets.
• Route Table: Configures routing for the public subnets.
• S3 Bucket: A private S3 bucket with a lifecycle policy to expire objects after 90 days.
• RDS Instance: A MySQL database instance with restricted access within the VPC.
• Security Groups: Ensures secure communication between resources.

The project is designed to follow best practices for security, scalability, and maintainability.

Prerequisites

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

1. Terraform Installed: Download and install Terraform from here.
2. AWS CLI Configured: Set up your AWS credentials using the AWS CLI or environment variables.
3. AWS Account: Ensure you have an AWS account with sufficient permissions to create the resources.
4. GitHub Repository: Fork or clone this repository.

---

Setup

1. Clone the Repository

git clone https://github.com/abaasi256/terraform-aws-ec2.git
cd terraform-aws-ec2

2. Initialize Terraform

Run the following command to initialize Terraform and download the required providers:

terraform init

3. Validate the Configuration

Validate the Terraform configuration for syntax errors:

terraform validate

4. Plan the Deployment

Preview the changes Terraform will make:

terraform plan

5. Apply the Configuration

Deploy the infrastructure:

terraform apply

6. Destroy the Infrastructure

When you no longer need the infrastructure, destroy it to avoid unnecessary costs:

terraform destroy

Resources Created

This Terraform configuration creates the following AWS resources:

1. VPC: A Virtual Private Cloud with a CIDR block of 10.0.0.0/16.
2. Subnets: Two public subnets in different availability zones.
3. Internet Gateway: Attached to the VPC for internet access.
4. Route Table: Routes traffic from the public subnets to the internet gateway.
5. S3 Bucket: A private bucket with a lifecycle policy to expire objects after 90 days.
6. RDS Instance: A MySQL database instance with restricted access.
7. Security Groups: Controls inbound and outbound traffic for the RDS instance.

Input Variables

The following input variables are used in this project:

Variable Name	Description	Default Value	Required
rds_password	Password for the RDS database	-	Yes

---

Outputs

After applying the configuration, Terraform will output the following:

Output Name	Description
vpc_id	ID of the created VPC
s3_bucket_name	Name of the created S3 bucket
rds_endpoint	Endpoint of the RDS instance
public_subnet_id	ID of the first public subnet
public_subnet_2_id	ID of the second public subnet
project_author	Author and project details

---

Best Practices

1. Secure Sensitive Data: Use Terraform's sensitive flag for sensitive variables like passwords.
2. Dynamic Availability Zones: Use AWS data sources to fetch availability zones dynamically.
3. Lifecycle Policies: Configure lifecycle rules for S3 buckets to manage object expiration.
4. Restrict Access: Use security groups and bucket policies to restrict access to resources.
5. Tagging: Tag all resources for better identification and cost management.
