Production Flask App with Monitoring

A real Flask app with Docker, monitoring, backups, and CI/CD. Built to show production-ready development practices.

🌟 LIVE DEMO

What This Is

I built this to demonstrate how I approach production applications. It's a Flask web app that includes everything you'd need for a real deployment:

• Docker containers for consistent deployment anywhere
• Prometheus monitoring to track performance and health
• Automated backups so you never lose data
• GitHub Actions CI/CD for automated testing and deployment
• Security scanning built into the pipeline
• Beautiful web interface that actually explains what's running

Quick Start

# Clone and run
git clone https://github.com/your-username/zero-to-prod-infra.git
cd zero-to-prod-infra
docker compose up

# Open your browser
open http://localhost:8000

That's it. The app will start, Prometheus will begin monitoring, and you can see everything running through the web interface.

What You'll See

Live Demo Features

• Professional web interface showcasing the project
• Architecture overview with clean design
• Technical stack explanation
• Quick start guide for developers
• Personal story about why I built this

When Running Locally

• Real-time system monitoring and metrics
• Interactive Flask application
• Prometheus dashboard with live data
• Automated backup system in action

The Stack

Backend: Python Flask with Gunicorn
Frontend: Bootstrap with live JavaScript updates
Monitoring: Prometheus with custom metrics
Deployment: Docker with multi-stage builds
Testing: Python unittest with 30+ test cases
CI/CD: GitHub Actions with security scanning
Backup: Automated system with rotation

Real-World Applications

This pattern works for:

• Startups building their first production app
• Internal tools at companies (dashboards, admin panels)
• API services that need monitoring and reliability
• Microservices in larger architectures

Project Structure

├── app/                    # Flask application
│   ├── app.py             # Main app with metrics
│   └── templates/         # Web interface
├── backup/                 # Automated backup system
├── prometheus/            # Monitoring configuration
├── .github/workflows/     # CI/CD pipeline
├── Dockerfile             # Container build
└── docker-compose.yml     # Service orchestration

Testing

# Run the test suite
python3 test_infrastructure.py

# Or run the interactive demo
python3 final-demo.py

All tests pass. The test suite validates every component from the Flask endpoints to the backup system.

Why I Built This

When applying for development roles, I wanted to show more than just code samples. This demonstrates:

1. Production thinking - health checks, monitoring, backups
2. DevOps skills - containerization, CI/CD, infrastructure as code
3. Security awareness - container hardening, vulnerability scanning
4. User experience - clear documentation, interactive interface

It runs entirely locally with no external dependencies or costs.

Deployment Ready

The app is designed to deploy anywhere:

• Local development with Docker Compose
• Cloud platforms like AWS, GCP, Azure
• Kubernetes clusters
• Traditional servers with systemd

All configuration is environment-based, so moving between environments is straightforward.
