Docker is a platform that enables developers to build, ship, and run applications in containers. Here's a quick overview for beginners:

📌 Key Features

  • Lightweight: Containers share the host OS, reducing overhead
  • Portable: Run anywhere with consistent environments
  • Efficient: Start quickly and scale easily
  • Secure: Isolate applications with built-in security
