title: Recover configuration of Grafana-docker persistent volume?
body: <p>I did a Grafana-docker deployment with persistent storage as said in <a href="https://github.com/grafana/grafana-docker#grafana-container-with-persistent-storage-recommended" rel="noreferrer">their GitHub</a> for doing tests for my company.
  I did exactly as they say (I paste) and it works:</p>
  
  <pre><code># create /var/lib/grafana as persistent volume storage
  docker run -d -v /var/lib/grafana --name grafana-storage busybox:latest
  
  # start grafana
  docker run \
    -d \
    -p 3000:3000 \
    --name=grafana \
    --volumes-from grafana-storage \
    grafana/grafana
  </code></pre>
  
  <p><strong>Problem</strong>: if I restart the server where it runs, <em>"I" lose all the configurations</em>, I mean, I cannot find how to start it taking the same volume (I'm sure it's there, but I could not find the way to start again the image with them). 
  I also do a <code>docker volume ls</code> and the output is quite difficult to understand</p>
  
  <p>I was checking on the documentation and trying commands, but no result, I was looking for the answer, but I could not find exactly how to recover the config in this case.
  How I can start it recovering the old volume, so, all the configs, dashboards, etc?
  Also: if possible, could also someone link to me the right guide to read and understand this? </p>
  
  <p>In advance, thanks a lot.</p>
