Variables

  • LOG_TO_STDOUT: If set to 1 output logs to stdout (retrievable using docker logs) instead of log volumes.

Description

Image providing PowerDNS DNS server.

When LOG_TO_STDOUT is set to 1, Docker image logs output to stdout and stderr. All stdout output is JSON.

You configure it by mounting a volume into /etc/powerdns/pdns.d with files to configure PowerDNS. For example, a simple pdns.conf file could look like:

# Disable recursion.
allow-recursion=

# We use dinit to assure the process is running.
guardian=no
daemon=no

# DNS master & slave.
master=yes
slave=no

# Allow AXFR.
disable-axfr=no
# Allow slave.
allow-axfr-ips=123.123.123.123/32

# To be anonymous.
version-string=anonymous

Enable Bind backend with pdns.simplebind.conf:

launch=bind
bind-config=/etc/powerdns/bindbackend.conf
bind-check-interval=3600

And your /etc/powerdns/bindbackend.conf could look like:

zone "example.com" {
  type master;
  file "/etc/powerdns/bind/example.com";
};

This example mounts an additional /etc/powerdns/bindbackend.conf file and additional directory /etc/powerdns/bind.

Of course you can also just extend this Docker image and add those files and directories there.

GitHub mirror

There is also a read-only GitHub mirror available, if you need to fork the project there.
