title: how does kubernetes detect docker daemon
body: <p>I'm using coreos tectonic sandbox. My deployment.yaml file contains the container which should detect the docker daemon running on host via kubernetes. 
  The container uses docker daemon to identify docker events. For some reason docker daemon is not getting detected. </p>
  
  <pre><code>deployment.yaml
  
  containers: 
    - name: idn-docker
      image: sample/id-docker:latest
        - name: docker-socket
          mountpath: /var/run/docker.sock
  </code></pre>
  
  <p>can some please help me identify what the problem is.</p>
