The error in question here is "failed to find fit". This generally happens when you have a port conflict (try and use the same hostPort too many times or perhaps you don't have any worker nodes/minions.
I'd suggest you either use the Vagrant file that is in the Kubernetes git repo (see http://kubernetes.io) as we have been trying to make sure that stays working as Kubernetes is under very active development. If you want to make it work with the CoreOS single machine set up, I suggest you hop on IRC (#google-containers on freenode) and try and get in touch with Kelsey Hightower.
