Configuration

The powerdns server can be configured using environment variables. See https://doc.powerdns.com/authoritative/settings.html# for further information.

All variables beginning with PDNS will be translated into a powerdns setting variable and included in pdns.conf.

Example:

PDNS_GMYSQL_HOST will become gmysql-host in pdns.conf.

For docker swarm it is also possible possible to configure some sensitive data from secret files. For that purpose add _FILE to the existing environment variable. The following secrets can be configured using secrets:

  • PDNS_GMYSQL_PASSWORD_FILE
  • PDNS_WEBSERVER_PASSWORD_FILE
  • PDNS_API_KEY_FILE
