When I first started using Docker, I could run containers, build images, and follow tutorials, and I thought I was “good enough.”

But in real systems, that’s where the gaps start showing.

→ Why is your image size 2GB?
→ Why does one small change rebuild everything?
→ Why does it work locally but break in production?

That’s when I realized the importance of understanding Docker at different levels.

And moving across these levels is what actually helps you:
→ debug faster instead of guessing
→ optimize systems instead of overbuilding
→ understand when to use containers vs other approaches

This is the difference between
“I use Docker” vs “I can design systems with it.”

If you’re serious about DevOps, this shift matters more than just learning commands.
