title: Kubeflow: Image Pull --> no space left on device
body: <p>Is there any way to clean all cached docker images etc from a kubernetes setup that could free up space on the master nodes?
  I try to install a deployment but the kubernetes prompts “no space left on device” while image pulling.</p>
  
  <p>I am kind of surprised that a 80GB disk is not enough for one simple deployment because the cluster is now completely emptied.</p>
  
  <p>Does anyone has an idea on how to wipe all unused docker image etc out?</p>
  
  <p>Thanks a lot!</p>
