Hi there! I've created a small service to automatically update load-balancer certificates on Hetzner cloud using go-acme/lego [0] and joohoi/acme-dns [1]. They lack support for Letsencrypt and this small service will update your certificates every two months. It's straight forward to install and used by Pirsch [2] in production.
Feedback welcome!
