🚀 Getting Started Guide

Option 1: Framework Template (Recommended for Beginners)

# 1. Choose your framework template
cp frameworks/react.Dockerfile Dockerfile

# 2. Get matching .dockerignore (optional but recommended)
curl -o .dockerignore https://raw.githubusercontent.com/ronald2wing/.dockerignore/master/frameworks/react.dockerignore

# 3. Build your application
docker build -t my-app .

# 4. Run your container
docker run -p 3000:3000 my-app

Option 2: Custom Combination (Advanced Users)

# 1. Create custom Dockerfile by combining templates
cat languages/nodejs.Dockerfile \
    patterns/multi-stage.Dockerfile \
    patterns/security-hardened.Dockerfile > Dockerfile

# 2. Review and customize
# Edit Dockerfile to match your application needs

# 3. Build with custom arguments
docker build \
  --build-arg NODE_ENV=production \
  --build-arg BUILD_ID=$(git rev-parse --short HEAD) \
  -t my-app:$(git rev-parse --short HEAD) .

# 4. Run with environment variables
docker run -d \
  -p 3000:3000 \
  -e NODE_ENV=production \
  --name my-app-container \
  my-app:latest

Option 3: Direct Download

# Download any template directly from GitHub
curl -o Dockerfile https://raw.githubusercontent.com/ronald2wing/Dockerfile/master/frameworks/react.Dockerfile

# Or use wget
wget -O Dockerfile https://raw.githubusercontent.com/ronald2wing/Dockerfile/master/languages/nodejs.Dockerfile

📋 Practical Examples

Example 1: Node.js Web Application

# Complete production setup for Node.js
cat languages/nodejs.Dockerfile \
    patterns/multi-stage.Dockerfile \
    patterns/security-hardened.Dockerfile > Dockerfile

# Build for production
docker build --target runtime -t my-node-app:prod .

# Run with resource limits
docker run -d \
  -p 3000:3000 \
  --memory="512m" \
  --cpus="1.0" \
  my-node-app:prod

Example 2: React Application with Alpine

# React with Alpine Linux optimizations
cat frameworks/react.Dockerfile \
    patterns/alpine.Dockerfile > Dockerfile

# Build and run
docker build -t my-react-app .
docker run -p 3000:3000 my-react-app

Example 3: Development Environment

# Development setup with hot reload
cat languages/nodejs.Dockerfile > Dockerfile
# Then edit Dockerfile to uncomment development configurations

# Build development image
docker build -t my-app:dev .

# Run with volume mounting for live reload
docker run -d \
  -p 3000:3000 \
  -v $(pwd):/app \
  -v /app/node_modules \
  my-app:dev

echo '{"name": "test", "version": "1.0.0"}' > package.json
echo 'console.log("Test successful")' > index.js

# Test build and run
docker build --no-cache -t template-test .
docker run --rm template-test

# Cleanup
docker rmi template-test
cd .. && rm -rf test-template

🏆 Best Practices

Security Best Practices

1. Always use specific versions of base images
2. Run as non-root user in production
3. Use multi-stage builds to exclude build tools
4. Scan images regularly for vulnerabilities
5. Set resource limits to prevent DoS attacks
6. Use .dockerignore to exclude sensitive files

Performance Best Practices

1. Order instructions carefully for optimal layer caching
2. Use Alpine or slim variants for smaller images
3. Clean package caches in the same RUN instruction
4. Use build arguments for environment-specific optimizations
5. Consider multi-architecture builds for broader deployment

Maintenance Best Practices

1. Update base images quarterly for security patches
2. Review templates annually for new best practices
3. Test with new Docker versions for compatibility
4. Document changes clearly for users and contributors
5. Engage with community for feedback and improvements
