Thank you for reporting @quixoticmonk. Unfortunately, I am not able to replicate that behaviour. Here is how I have tried it in `bash` ```bash $ docker run --rm -i hadolint/hadolint:v1.17.7...

Sounds good to me. I can not imagine a reason why this should not be caught as an issue in any production image. It would be great if you can...

Thank you for raising this issue. I understand your frustration with broken docker image builds. However, when your dependency is upgraded your image is not the same it was before...

In my experience, moving tags are common practice for most popular public images like `alpine`, `ubuntu`, `node`, `python`, etc. and most people have more than one tag for one image...
