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.
