🐳 Docker — The Modern Way to Run Applications

Docker provides lightweight containers that bundle your app with all required dependencies, ensuring it runs exactly the same everywhere — laptop, server, or cloud.

🚀 Benefits

• Fast: Starts in milliseconds
• Lightweight: No full OS like VMs
• Portable: Move across any environment
• Consistent: Same behavior in dev → prod
• Scalable: Ideal for microservices & CI/CD

🧱 Key Components

• Docker Image (template)
• Docker Container (running instance)
• Dockerfile (build instructions)
• Docker Hub (image registry)

👉 DBAs & developers use Docker to run PostgreSQL, MySQL, MongoDB & full stack environments in seconds!

🎯 One Line:
Docker = Package once → run anywhere, fast & reliably.
