A Docker container for a PowerDNS superslave.
This container runs PowerDNS in superslave mode with the sqlite backend. It exposes port 53 by default and takes the PDNS_SUPERMASTERS environment variable for configuration on container start. PDNS_SUPERMASTERS holds a space-separated list of DNS master servers, where each is in the format <IP Address>:<Server name>.
This also supports TSIG_SUPERMASTER and TSIG_NOTIFY environment variable to support PowerDNS's allow-unsigned-supermaster and allow-unsigned-notify=no flags.
