<p>i am unable to start the kube-apiserver on my 1 master node cluster. the kubelet keeps on trying to start the service but get all the time CrashLoopBackOff. 
i tried to run the container using the <code>docker run</code> command and i m getting the following log
i don't understand why i can't see the service <code>6443</code> or <code>443</code> on listening when i do <code>netstat</code>.</p>
