How to properly use dockerfile_image? about rules_docker HOT 4 OPEN

Did you manage to solve this? I am too finding it hard to find any docs.

So the idea behind rules_docker is to not require a docker context and a dockerfile, for the RHEL case you need to use bazeldnf and install the RPMs through it, but take into account that it will not execute any of the post install scripts. And there are some caveats with some packages that can't be installed so easily.

Thanks for your response. I managed to get it working, on this occasion I needed a few libraries inside the image for my app to work. I don't know how this would be achievable without a custom base image being built somewhere, that somewhere for me was best along side the application code which is why I came to use the dockerfile_image repository rule.

Would it be worth me/anyone expanding the documentation showing the use of the repository_rule?

This repo is in kind of maintenance/archive mode, rules_oci is where all the fun is happening right now, adding dependencies to images is not something a lot of folks though, most of the time you build some sort of binary with bazel (even if it's not a binary but something that's entirely self-contained) and that gets added to the image.

At Booking we have an entire setup where we start from scratch and we install the required RPMs with bazeldnf into some of our base images, but it's not open source and I've never taken the time to make a smaller repo to show how it works
