Docker in simple words for AI developpers in 2025

Imagine you’re building a Lego house.

• The Problem: You have all the bricks, but building it on your living room floor might be messy and hard to move.
• The Solution: You get a sturdy box (the « container »).
  • You carefully place all the bricks and instructions inside.
  • Now, you can easily move the whole box anywhere – your friend’s house, a park, etc.
  • The box keeps everything together, ensuring the house is built the same way everywhere.

Docker is like that box for your software applications:

• Instead of Legos, you have:
  • Code (the instructions)
  • Libraries (the special bricks)
  • System settings (how the house should be built)
• Docker creates a « container » for your software:
  • This container packages everything together neatly.
  • It ensures your software runs the same way on any computer (your laptop, a server, the cloud).

Why is this useful?

• Consistency: Your software always behaves the same, no matter where it runs.
• Portability: Easily move your software between different environments.
• Efficiency: Containers are lightweight and start quickly.
• Isolation: Each container runs independently, preventing conflicts between applications.

In simple terms, Docker helps you:

• Package your software neatly.
• Run it consistently anywhere.
• Make your life as a developer easier!
