How is this docker?

[OfficialAudite]

It is a shell script. But I mean why not just make a dockerfile or docker-compose and at the same time provide where to download all the mods or something like that to put into /mods and then mount it in docker ? So you would have mounted world etc? Since this is far away from docker.

Since this https://www.curseforge.com/minecraft/modpacks/ragnamod-vi claims that this is docker....
