Question about Skydock Setup

[brandonparsons]

Hi there,

I'm new to docker (and skydock obviously) and trying to get set up. In the README, you state the following:

First get the IP address of the docker0 bridge. We will need to know the IP of the bridge so that we can tell skydns to bind it's nameserver to that IP.

Is there a simple way to get the IP Address of the docker0 bridge? I can obviously spin up container and do ifconfig, but wondering if docker had a command to get this information out so that in an upstart script it would be easy to run the skydns container on the right IP.

Thanks!

The docker0 is an interface on your host. So just do a ifconfig on the machine that is running docker and you should see the docker0 interface.

Ah gotcha. Googled for the following to grab the IP for an upstart script or whatever:

ifconfig docker0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'
