Just updated my blog post with a link to original docker file 👆
There was no Docker support until three weeks ago. The author added it and I helped with some other missing aspects, mainly support for linux/arm64 (Raspi 4)
Also this repository contains an easy way to create your own image, upload to your own repo (mine is at https://hub.docker.com/repository/docker/bitman09/hrconvert2/tags?page=1&ordering=last_updated) and kubernetes support
I agree with @trolololol@lemmy.world here. Could you describe what issues are people having? What is their user profile (programmers, writers, …)?
