Unable to start pod - context deadline exceeded error

Question

We are currently trying to launch a pod on our kubernetes cluster. The pod get stuck in the Waiting state (ContainerCreating reason) forever.

When getting details about the pod (kubectl describe pod pod01), the only event that's present is:

Events:
  Type     Reason      Age                     From     Message
  ----     ------      ----                    ----     -------
  Warning  FailedSync  2m29s (x439 over 125m)  kubelet  error determining status: rpc error: code = DeadlineExceeded desc = context deadline exceeded

From the various posts I found on the web, it can possibly mean that kubelet timing out while trying to contact etcd.

Is that correct? How could I troubleshoot that further?

Thanks in advance,

Emmanuel
