If it's using nix for building - there's multiple ways to DIY turn that into a docker container, like pkgs.dockerTools.buildImage or nixpacks:

IHP is really easy to package with nix nowadays. In fact the official docker building also just uses `pkgs.dockerTools.buildImage` and calls nix-build :) Most people with nix experience can easily figure out how to do exactly the same thing as the "official" way.
