title: Minikube cluster not responding
body: <p>This is my current status of my minikube on my MAC.</p>
  
  <pre><code>minikube: Running
  cluster: Stopped
  kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100
  </code></pre>
  
  <p>when I tried running a 'minikube start' I get the below errors:</p>
  
  <pre><code> Starting local Kubernetes v1.9.4 cluster...
      Starting VM...
      E0919 14:31:51.762390   11784 start.go:159] Error starting host: 
      Temporary Error: Error configuring auth on host: Temporary Error: ssh 
      command error:
      command : sudo systemctl -f restart docker
      err     : Process exited with status 1
      output  : Job for docker.service failed because the control process 
      exited with error code.
      See "systemctl  status docker.service" and "journalctl  -xe" for details.
  </code></pre>
  
  <p><strong>Any pointers to the above problem's resolution will be great.</strong></p>
