title: gcloud: how to download the app via cli
body: <p>I depolyed an app with gcloud preview app deploy.</p>
  
  <p>Is there a way to download it to an other local machine?
  How can I get the files? I tried it via ssh with no success (can't access the docker dir)</p>
  
  <p>UPDATE:
  I found this:</p>
  
  <pre><code>gcloud preview app modules download default --version 1 --output-dir=my_dir
  </code></pre>
  
  <p>but it's not loading files </p>
  
  <p>Log</p>
  
  <pre><code>Downloading module [default] to [my_dir/default]

  |- Downloading [0] files...                                 -|
