            "type": "Ready",
            "status": "Unknown",
            "lastHeartbeatTime": "2015-11-12T06:03:19Z",
            "lastTransitionTime": "2015-11-12T06:04:03Z",
            "reason": "Kubelet stopped posting node status."
          }

Answer 1

Follow these steps:

Get nodes

kubectl get nodes

Describe node

kubectl describe node 192.168.1.157

You’ll probably get status of the node as unknown

Login in node and Restart kubelet

/etc/init.d/kubelet restart

Get nodes again

On the master:

kubectl get nodes

This worked for me

In Azure, if you are using acs-engine install, you can find the shell script that is actually being run to provision it at:

/opt/azure/containers/provision.sh

run as root:

systemctl enable kubectl
systemctl restart kubectl
