Learning Docker is easy.
Learning Docker the way DevOps engineers actually use it is different.
This repository is my structured, practical, and real-world Docker learning path where I:
- Practice every concept
- Document commands and outputs
- Build mini projects
- Understand how Docker works in production
📌 This is not copied theory — it’s learning by doing.
