Project Overview

This repository contains a Docker-optimized full-stack application featuring:

• Frontend: React.js (Create React App)
• Backend: Node.js REST API
• Database: MongoDB with persistent storage
• Infrastructure: Docker containers with multi-stage builds

Optimized Deployment Architecture

Key Improvements in v2.0:

1. 68% Size Reduction (From 180MB to 58MB per service)
2. Security Hardening (Non-root users, read-only filesystems)
3. Build/Runtime Separation (Multi-stage Dockerfiles)
4. Health Monitoring (Container healthchecks)
5. CI/CD Ready (GitHub Actions workflow)

Prerequisites

Tool	Version	Installation Guide
Docker Engine	20.10+	Official Guide
Docker Compose	2.5+	Official Guide
Node.js	16+	NVM Guide

Getting Started

1. Clone Repository

git clone https://github.com/Vinge1718/yolo.git
cd yolo
2. Build and Run (Development)
bash
docker compose up -d --build
3. Build and Run (Production)
bash
DOCKERFILE=Dockerfile.prod docker compose -f docker-compose.prod.yml up -d --build
Access endpoints:

Frontend: http://localhost:3000

Backend API: http://localhost:5000

MongoDB: mongodb://localhost:27017
## Docker Configuration

### Production vs Development Builds

| Feature                | `Dockerfile` (Dev)               | `Dockerfile.prod` (Production)       |
|------------------------|-----------------------------------|---------------------------------------|
| **Base Image**         | `node:16-alpine`                 | `alpine:3.18` + Node runtime only     |
| **Dependencies**       | Includes devDependencies         | Only production dependencies          |
| **User Context**       | Root (for debugging)             | Dedicated non-root user (`appuser`)    |
| **Build Process**      | Single-stage                     | Multi-stage with build separation     |
| **Health Checks**      | Basic                            | Comprehensive endpoint monitoring     |
| **Filesystem**         | Read/Write                       | Read-only where possible              |
| **Size**               | ~180MB                           | ~58MB (68% reduction)                |
| **Security**           | Standard                         | Non-root user, minimized privileges   |
| **ENTRYPOINT**         | None                             | `tini` init system                    |
| **Caching**            | Basic layer caching              | Optimized dependency caching          |
| **Debugging**          | Full source access               | Only built artifacts                  |
| **Use Case**           | Development/testing              | Production deployments                |
