freshbooks/dnsmasq repository overview

⁠docker-dnsmasq

It's a dnsmasq⁠ Docker image. It is only 6 MB in size. It is just an ENTRYPOINT to the dnsmasq binary. Can you smell what the rock is cookin'?

⁠Usage

dnsmasq⁠ requires NET_ADMIN capabilities to run correctly. Start it with something like docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN andyshinn/dnsmasq.

The configuration is all handled on the command line (no wrapper scripts here). The ENTRYPOINT is dnsmasq -k to keep it running in the foreground. If you wanted to send requests for an internal domain (such as Consul) you can forward the requests upstream using something like docker run -p 53:53/tcp -p 53:53/udp --cap-add=NET_ADMIN andyshinn/dnsmasq -S /consul/10.17.0.2. This will send a request for redis.service.consul to 10.17.0.2
