I'm running two authoritative DNS-Server (Primary and Secondary) for some domains, for which I want to get Certificates through this project. Therefore I am running acme-dns in a docker container and I just forward the queries, because I don't have another public IP. And to be honest, I don't want to get one just for the certificates. It would be nice, if acme-dns clould be set as master and just notify the other authoritative DNS-Servers for that zone.
