title: Getting error while running the Mesos container in mesos cluster using marathon
body: <pre><code>"container": {
      "type": "MESOS",
      "docker": {
        "image": "redis",
        "forcePullImage": false
      }
    }
  </code></pre>
  
  <ol>
  <li>The above example has the container type as Mesos..but again specifying "docker" image... for using universal container or mesos container, do we need to install docker?</li>
  <li>because, when i try to run a sample in mesos with type "mesos" container, i am getting error like this:</li>
  </ol>
  
  <blockquote>
    <p>unsupported container image:DOCKER.</p>
  </blockquote>
  
  <p>I have not installed docker.</p>
  
  <ol start="3">
  <li>I am using Mesos1.1 version</li>
  </ol>
