What is Docker?

A tool that packages your application and everything it needs to run into a standardised container

Why It Matters

Docker ensures your app runs the same everywhere, eliminating 'it works on my machine' problems

Real-World Example

A Docker container includes your app, Node.js, and all libraries, running identically on any server

“Understanding terms like Docker matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”

Callum Holt, Founder, 13Labs
