I have started to experiment with kubernetes in my off time.  First things first, I need to know a little more about CoreOS.  The folks at CoreOS have made it exceedingly easy to pull the system down and get it running.

Simply change the config.rb to have the number of instances and change the user-data to include a link to the etcd directory where your key value pairs will exist for the cluster, and away you go.

I now have a 3 node CoreOS cluster running inside vagrant/virtualbox.  I plan to test out some container distribution to see how quickly one can recover from loss of a system.

If you would like to follow along with me, what you need is VirtualBox and Vagrant to start with and then clone the CoreOS.  Tweak the user-data and config file and then “vagrant up” as always.
