I'd like to ensure that my Dockerfile does not have any warnings and that it's validated in CI. If I use a simple job such as:

container:runs-on:ubuntu-24.04steps:      -name:Build Container Imageuses:docker/build-push-action@v6with:push:false

Will this fail ifdocker build --check fails? I don't see any documentation in the README about if lint warnings are checked. I think the documentation could be improved here.

If theyaren't checked, I'd propose a new

with:checked:true

flag so that users can lint their Dockerfiles using this action in CI.
