This is a PostgreSQL-enabled PowerDNS docker container, built specifically for the needs of Discourse. It may or may not be generally useful.

It was based on a MySQL-targeted docker build by psi-4ward, however it has diverged significantly.

Usage

Run it just like any other container, using environment variables to point it at a PostgreSQL server that has been loaded with the standard PowerDNS schema, or at least something vaguely resembling it.

For example:

docker run --name powerdns \
  -e PGSQL_HOST=localhost \
  -e PGSQL_PORT=5432 \
  -e PGSQL_USERNAME=pdns \
  -e PGSQL_PASSWORD=pdns \
  -e PGSQL_DATABASE=pdns \
  discourse/powerdns

Configuration

All behaviour of this image are controlled via environment variables. All are optional.

• PGSQL_HOST (default: localhost) -- a hostname, IP address, or socket directory path (if the given value begins with a /) that should be used to connect to PostgreSQL.

• PGSQL_PORT (default: 5432) -- the port number to connect to.

• PGSQL_USERNAME (default: pdns) -- the username to use to authenticate to PostgreSQL.

• PGSQL_PASSWORD (default: random string) -- the password to use to authenticate to PostgreSQL.

• PGSQL_DATABASE (default: pdns) -- the name of the database to connect to on the PostgreSQL server.

• PGSQL_DNSSEC (default: yes) -- whether or not to enable DNSSEC on the backend.

PowerDNS Configuration

If you have a need to configure PowerDNS in a particular way, you can mount a configuration directory on /etc/powerdns/pdns.d containing .conf files with configuration directives.
