Image **pdns-pgsql** contains completely configurable [PowerDNS 4.x server](https://www.powerdns.com/) with postgres backend (without postgres server). Image **pdns-recursor** contains completely configurable [PowerDNS 4.x recursor](https://www.powerdns.com/). Image **pdns-admin** contains fronted (Caddy) and backend (uWSGI) for the [PowerDNS Admin](https://github.com/PowerDNS-Admin/PowerDNS-Admin) web app, which is written in Flask and used for managing PowerDNS servers.

 The PowerDNS server is configurable via env vars. Every variable starting with `PDNS_` will be inserted into `/etc/pdns/pdns.conf` conf file in the following way: prefix `PDNS_` will be stripped away and every `_` will be replaced with `-`. For example, from the above mysql config, `PDNS_gmysql_host=mysql` will became `gmysql-host=mysql` in `/etc/pdns/pdns.conf` file. This way, you can configure PowerDNS server in any way you need within a `docker run` command.
 
-The `SUPERMASTER_IPS` env var is also supported, which can be used to configure supermasters for a slave DNS server. [Docs](https://doc.powerdns.com/md/authoritative/modes-of-operation/#supermaster-automatic-provisioning-of-slaves). Multiple IP addresses separated by spaces should work.
