title: How to use volumes-from in marathon
body: <p>I'm working with mesos + marathon + docker quite a while but I got stuck at some point. At the moment I try to deal with persistent container and I tried to play around with the "volumes-from" parameter but I can't make it work because I have no clue how I can figure out the name of the data box to put it as a key in the json. I tried it with the example from <a href="https://github.com/mesosphere/marathon/blob/5f9ed0248805f231cd2900b429b0cb85217f92fe/docs/docs/native-docker.md">here</a></p>
  
  <pre><code>    {
      "id": "privileged-job",
      "container": {
          "docker": {
              "image": "mesosphere/inky"
              "privileged": true,
              "parameters": [
                  { "key": "hostname", "value": "a.corp.org" },
                  { "key": "volumes-from", "value": "another-container" },
                  { "key": "lxc-conf", "value": "..." }
              ]
          },
          "type": "DOCKER",
          "volumes": []
      },
      "args": ["hello"],
      "cpus": 0.2,
      "mem": 32.0,
      "instances": 1
  }
  </code></pre>
  
  <p>I would really appreciate any kind of help :-)</p>
