Final Architecture Documentation

# docs/architecture.md # System Architecture ## High-Level Overview This project implements a complete DevOps pipeline with the following components: ### Application Layer - **Technology**: Python 3.11 with Flask framework - **Purpose**: REST API serving JSON responses - **Endpoints**: Health check, info, status - **Configuration**: Environment variables ### Container Layer - **Runtime**: Docker with multi-stage builds - **Base Image**: python:3.11-slim (optimized) - **Security**: Non-root user, health checks - **Registry**: Docker Hub ### Infrastructure Layer - **Provider**: Amazon Web Services (AWS) - **Compute**: EC2 t2.micro instance - **Network**: Custom VPC with public subnet - **Security**: Security groups (SSH, HTTP, App port) ### CI/CD Pipeline - **Platform**: GitHub Actions - **Stages**: Test → Build → Push → Deploy - **Triggers**: Push to main, Pull requests - **Deployment**: SSH-based Docker deployment ## Data Flow 1. Developer pushes code to GitHub 2. GitHub Actions triggers CI/CD pipeline 3. Pipeline runs automated tests 4. Docker image built and pushed to registry 5. Pipeline SSHs to EC2 and deploys new container 6. Application accessible via public IP ## Security Measures - Secrets stored in GitHub Secrets - Non-root container user - Security groups limit network access - SSH key authentication - No hardcoded credentials ## Monitoring - Container health checks - Application health endpoint - Docker logs for debugging - CloudWatch (optional)

Demo Script

LIVE DEMONSTRATION SCRIPT STEP 1: Show Repository Structure ───────────────────────────────── "Here's our GitHub repository with all the code organized into logical directories: app, docker, terraform, and workflows." # Terminal commands: cd capstone-project tree -L 2 STEP 2: Show Current Deployment ─────────────────────────────── "The application is currently running on AWS EC2. Let's verify it's working:" # Terminal commands: curl http://EC2_IP:8000/health | jq . curl http://EC2_IP:8000/api/info | jq . STEP 3: Make a Code Change ────────────────────────── "Now I'll make a small change to trigger our CI/CD pipeline:" # Terminal commands: echo "# Demo change $(date)" >> README.md git add README.md git commit -m "Demo: trigger CI/CD pipeline" git push origin main STEP 4: Monitor Pipeline ──────────────────────── "Watch the GitHub Actions pipeline run through all stages:" # Show GitHub Actions page # Point out: Test → Build → Deploy stages # ~3-5 minutes to complete STEP 5: Verify New Deployment ───────────────────────────── "Pipeline complete! Let's verify the new deployment:" # Terminal commands: curl http://EC2_IP:8000/health | jq . docker logs capstone-app --tail 5 # (if SSH'd into EC2) STEP 6: Show Infrastructure Code ──────────────────────────────── "All infrastructure is managed as code with Terraform:" # Show terraform files cat terraform/main.tf terraform output

Backup Demo (If Live Demo Fails)

BACKUP DEMONSTRATION PLAN If live demo encounters issues, use pre-recorded videos or screenshots: 1. Pre-recorded pipeline execution (screen recording) 2. Screenshots of: - GitHub repository structure - GitHub Actions successful run - API responses in Postman/browser - EC2 instance in AWS Console - Terraform state output 3. Local Docker demo: docker-compose up -d curl http://localhost:8000/health docker logs capstone-app 4. Code walkthrough: - Explain Dockerfile stages - Walk through GitHub Actions YAML - Show Terraform resource definitions

🔬 Hands-on Lab (1.5 Hours)

Lab 1: Finalize Documentation

# Update all documentation cd capstone-project # Add CI/CD badge to README # Get badge URL from GitHub Actions page # Create CONTRIBUTING.md cat > CONTRIBUTING.md << 'EOF' # Contributing Guide ## Getting Started 1. Fork the repository 2. Clone your fork 3. Create a feature branch ## Development 1. Make changes 2. Run tests: `pytest tests/ -v` 3. Build Docker: `docker build -t capstone-app -f docker/Dockerfile .` ## Pull Request 1. Push changes to your fork 2. Open PR against main branch 3. Ensure CI passes 4. Request review EOF # Create LICENSE cat > LICENSE << 'EOF' MIT License Copyright (c) 2024 Your Name Permission is hereby granted, free of charge, to any person obtaining a copy of this software... EOF # Commit documentation git add . git commit -m "Final documentation updates" git push origin main

Lab 2: Practice Demo

# Demo practice checklist: □ Test all curl commands work □ Verify GitHub Actions is ready □ Check EC2 instance is running □ Prepare terminal windows □ Clear terminal history □ Test screen sharing □ Have backup slides ready # Quick verification before demo: APP_IP=$(cd terraform && terraform output -raw instance_public_ip) echo "Pre-demo verification:" echo "1. App health: $(curl -s http://$APP_IP:8000/health | jq -r '.status')" echo "2. GitHub Actions: Check recent runs" echo "3. Docker Hub: Verify latest image" # Prepare demo command history: history -c curl http://$APP_IP:8000/health | jq . curl http://$APP_IP:8000/api/info | jq .
