title: Cloned git not in Docker Volume?
body: <p>I use the following Dockerfile:</p>
  
  <pre><code>FROM centos
  VOLUME ["apitests"]
  RUN su
  RUN yum -y install git
  RUN git clone https://github.com/Human-Connection/CUBE-arduino-yun.git /apitests/
  </code></pre>
  
  <p>then I build my image</p>
  
  <pre><code>docker build -t apitesting .
  </code></pre>
  
  <p>and start a container with a shell</p>
  
  <pre><code>docker run -ti apitesting /bin/bash
  </code></pre>
  
  <p>Now I find /apitests within the container.
  But I cannot find the cloned git data.</p>
  
  <p>What am I doing wrong?</p>
