Thanks for the shout out!
Full disclosure, I use podman, not docker. If anyone has any issues with this using docker, let me know and I'll get it fixed ASAP. I'm not 100% sure the --device option works the same way with docker.
I added instructions on how to add the nvidia-container-toolkit repo on the two distros I have (one rpm based, one deb based). If adding the repo is different on your distro, please consider adding it to the instructions. The instructions on the nvidia-container-toolkit web page are... subpar in my opinion.
