Rancher does a lot of black magic with the machine drivers behind the scenes, to try to auto-map a configuration UI and send the correct parameters to the drivers. Therefore, simply adding this machine driver to Rancher won't work anymore for RKE2 clusters. It requires some adjustments to the driver, to make it work as expected with Rancher. As these are deriving from the default Docker-machine use-case and circumventing some implemented guardrails, I created a fork of this repository with the required changes. I also implemented an RKE2-compatible Rancher UI extension on top, to make cluster management via Rancher in Hetzner cloud easier.

Thank you for that @nils-bq. I only know the docker-machine side of things, and to this day I have not worked with Rancher, so these kinds of issues are kind of hard for me to debug or provide help with.

@JonasProgrammer that's also why I made a fork instead of a PR. The changes I needed to make for good Rancher compatibility make the actual Docker-machine interface worse. Not sure if it makes sense to try and find a common ground here.
