Rancher 1.0.1 + k8s: Unexpected Token U doing anything

I set up a 3 node cluster, and then created a kubernetes environment. Creating the environment worked well,
and i can successfully do kubectl:

> kubectl version
Client Version: version.Info{Major:"1", Minor:"1", GitVersion:"v1.1.7", GitCommit:"e4e6878293a339e4087dae684647c9e53f1cf
9f0", GitTreeState:"clean"}
Server Version: version.Info{Major:"1", Minor:"2+", GitVersion:"v1.2.0-rancher-1", GitCommit:"ed6532f975cff184196dbe214d
e8fa0198b415ef", GitTreeState:"clean"}

The problem I’m having is that any attempt to create a namespace, service, pod, or anything, I get this error:

“Unexpected token u”

This happens even when i use the “Manage environments” to create a new namespace:

apiVersion: v1
kind: Namespace
  name: "dave-ns"

Or in fact any service, pod, or rc defintion.

It is also worth mentioning that it takes a long time to come back when I click save-- like 30 seconds.

Looking at all of my containers, the only unusual thing I see is that the two kubelet containers appear to be constantly restarting. Here are the log entries from one of the containers:

I checked that the cluster ur http://csc-docker-3.colinx.com/v1 can be reached from both nodes.

In previous rancher installations, I had problems with access control enabled, so just be sure, i re-started this cluster completely fresh, and didnt even enable access control this time.

What’s wrong?
