Power DNS server
This image serves a PwerDNS server. It allows configuring:
- SOCKET_DIR: where unix socket will be saved.
- AXFR_IPS: By default uses 127.0.0.0/8, but can be changed if your pdns will be part of a master,slave dns cluster. However, PowerDNS uses [other mechanisms for replication]((https://doc.powerdns.com/authoritative/modes-of-operation.html)
- SQLITE_DATABASE: sqlite db path. By default
/var/lib/powerdns/pdns.sqlite3. Be careful to save this file in a volume.
- API_KEY: which API KEY will be used for REST API. If not defined, a random one will be generated. For production installations setting this variable is mandatory.
