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
