Docker didn’t become popular because it’s fancy.
It became popular because developers were tired of wasting time fixing environment issues instead of building features.
Over time, I realized something important:
👉 Docker is not just about containers.
👉 It’s about consistency and discipline.
Same app.
Same dependencies.
Same behavior — on my laptop, your laptop, CI, and production.
That alone removes a huge category of problems.
A few things Docker taught me:
Start simple, don’t over-engineer
One container should do one job
Docker won’t fix bad design — it exposes it faster
Teams move faster when everyone runs the same setup
Docker doesn’t make you a better engineer by default.
But it amplifies good engineering practices.
