PowerDNS provider

Tested and confirmed to work with PowerDNS authoratative server 3.4.8 and 4.0.1. Refer to PowerDNS documentation instructions on how to enable the built-in API interface.

PowerDNS Notes:

  • PowerDNS API does not currently support SSL, therefore you should take care to ensure that traffic between lego and the PowerDNS API is over a trusted network, VPN etc.
  • In order to have the SOA serial automatically increment each time the _acme-challenge record is added/modified via the API, set SOA-API-EDIT to INCEPTION-INCREMENT for the zone in the domainmetadata table



Package pdns implements a DNS provider for solving the DNS-01 challenge using PowerDNS nameserver.
