🐳 What is Docker? (aka Containers)

Imagine you’re at school and every student brings their own lunchbox. Inside the lunchbox is everything they need for lunch: their sandwich, juice, spoon, napkin, maybe even a tiny dessert.

That’s Docker.

A Docker container is like a lunchbox for software. It has:

• The application (like a web server or app)
• The tools and libraries it needs to run
• It doesn’t bring the whole kitchen — just what it needs

And the best part? You can take that container and give it to another computer — and it’ll run the same way, every time. Super portable. Super light.
