Configuration

Environment Configuration:

All of environment variables with PDNS_ prefix are saved to /etc/pdns/pdns.conf according to following rules:

• do nothing if /etc/pdns/pdns.conf exists already

• if name has _FILE suffix - read value from file and rename suffix

• remove PDNS_ prefix

• replace _ with -

• lowercase variable name

• write resulting name and value fo file

• To support docker secrets, use same variables as above with suffix _FILE.

• Want to disable mysql initialization? Use MYSQL_AUTOCONF=false

• DNSSEC is disabled by default, to enable use MYSQL_DNSSEC=yes

• Want to use own config files? Mount a Volume to /etc/pdns/conf.d or simply overwrite /etc/pdns/pdns.conf

PowerDNS Configuration:

Append the PowerDNS setting to the command as shown in the example above. See docker run --rm ghcr.io/dopos/powerdns-alpine --help
