I shipped DockRx: analyze Dockerfiles like a doctor, not a linter

I got tired of Dockerfile linters that dump warnings with no sense of priority.

So I built DockRx — it scores a Dockerfile, ranks the highest-ROI fixes (size, cache, hardening), and can preview non-destructive rewrites.

• Playground (no install): https://dockrx.vercel.app
• Install: pip install dockrx
• GitHub: https://github.com/kiwi-07/docrx
• Detailed Blog : ankitpatil.pages.dev/blog/dockrx

It’s alpha and honest about it: estimates are heuristic, auto-fix covers a subset of rules. Feedback welcome — especially where the scoring feels wrong.

Question for you

What’s the Dockerfile warning you see most and usually ignore?

If you try DockRx on a real file and the score feels wrong, tell me what it got wrong — that feedback is how the roadmap gets ordered.
