Usage

Specifying downstream servers directly

It is possible to specify downstream servers directly on the docker command line:

docker run -d -p 53:53 -p 53:53/udp tmuncks/dnsdist:latest 8.8.8.8 8.8.4.4

Mounting configuration file

The image becomes a lot more flexible when using a configuration file.

Mount a full PowerDNS dnsdist configuration on /etc/dnsdist/dnsdist.conf in the container.

Please note: The container ENTRYPOINT specifies --local=0.0.0.0 which effectively disables setLocal() statements in the configuration file.
