Unable to get SkyDock (SkyDNS) running on Docker-For-Mac Beta Version 1.12.0-rc4-beta19 (build: 10258)

When following the instructions on readme.md I get the following error when trying to run the SkyDNS container.

jimb$ docker run -d -p 172.17.42.1:53:53/udp --name skydns crosbymichael/skydns -nameserver 8.8.8.8:53 -domain docker

I suspect this may be related to the following issue:
moby/moby#22753

Could anyone confirm this?

This is the output of my docker info

@jimthree if you are doing docker for mac you have the new version of docker installed. This version has a dns server built in so there is no need for skydock anymore. You should give it a try, i think you will like it
