We have deployed Kubernetes using OpenStack Heat on CoreOS. The below command of fetching nodes does not get any results:

kubectl -s http://<Master FIP>:8080 get nodes

On looking at the minion, we saw that kubelet cannot talk to the master. kubelet on minion has these errors.

In the master node, the container - hyperkube controller displays the below error (10.0.0.4 is the private IP for the master):

W0909 17:42:34.411146       1 request.go:347] Field selector: v1 - serviceaccounts - metadata.name - default: need to check if this is versioned correctly.

E0909 17:43:04.284611       1 nodecontroller.go:434] pods "kube-apiserver-10.0.0.4" not found

I am not sure how should we debug this. Could someone please suggest what could be wrong.

Thanks
