kubernetes_asyncio: Example in the README will not run because of "pods is forbidden"

I’m running the example in the README for the repo, and I cannot get it to work:

HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"pods is forbidden: User \"system:anonymous\" cannot list pods at the cluster scope","reason":"Forbidden","details":{"kind":"pods"},"code":403}

If the client is supposed to read the default kube config (which I think it does), it somehow cannot authenticate correctly. Is this a bug? Or is my usage incorrect?
