I do this exactly, using ACME DNS:

https://github.com/acme-dns/acme-dns

CAUTION, though, the last time I downloaded a binary release, ClamAV triggered on it, so I kept my old version which worked. I was using the 1.0 series (without any problems!), and now it seems the project has picked up development again with a 2.0 series.
