    ports:
      - "80:80"
    volumes:
      - ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
      - .:/var/www/html
    depends_on:

Use Case: Laravel Application

# Run Laravel
docker-compose up -d

# Install dependencies
docker-compose exec php composer install

# Run migrations
docker-compose exec php php artisan migrate

# Seed the database
docker-compose exec php php artisan db:seed

Everyday Use Case

Case: A developer needs to run Laravel.

# Build
docker-compose build

# Run
docker-compose up -d

# Artisan commands
docker-compose exec php php artisan migrate
docker-compose exec php php artisan make:model Student

Best Practices

1. Use alpine: For a smaller image
2. Multi-stage build: For production
3. Non-root user: For security
4. Health check: For monitoring

Conclusion

Laravel in Docker is easy to set up. Use docker-compose to manage Nginx, PHP-FPM, and MySQL.
