title: why does kubeflow pipeline always pull the image "busybox"
body: <p>I'm now using kubeflow pipeline in a local environment which has no network
  I have wrote a pipeline with only one components, I have build the image for it
  but the pipeline always fail, because it fails to pull the busybox image from internet
  I have two questions:</p>
  <ol>
  <li>why does kubeflow pipeline always pull the image &quot;busybox&quot; ?</li>
  <li>how can I solve it ?</li>
  </ol>
  <p>I have pull busybox manually but it doesn't work, I guess the pipeline needs the latest busybox image, so it will pull everytime</p>
