AWS Infrastructure Automation using Terraform & GitLab CI/CD

This project demonstrates an end-to-end CI/CD pipeline that provisions AWS infrastructure using Terraform and deploys a Dockerized Nginx application on an EC2 instance.

🚀 Features

• Infrastructure provisioning using Terraform (VPC, Subnet, EC2, Security Groups)
• CI/CD automation using GitLab CI
• Secure SSH key generation using Terraform TLS provider
• Docker-based Nginx deployment
• Automated application testing
• Manual infrastructure teardown

🛠️ Tech Stack

• AWS (EC2, VPC, Security Groups)
• Terraform
• GitLab CI/CD
• Docker
• Linux

📂 Pipeline Stages

1. Apply – Provisions AWS infrastructure
2. Deploy – Deploys Dockerized Nginx to EC2
3. Test – Verifies application availability
4. Destroy – Manually destroys infrastructure

🔐 Security

• No hardcoded secrets
• SSH keys generated dynamically
• Artifact-based key handling across pipeline stages

📌 Usage

1. Configure AWS credentials as GitLab CI variables
2. Run pipeline
3. Access application via EC2 public IP

• GitLab pipeline success
• Nginx running in browser
