title: Docker container CPU allocation
body: <p>I have created a container:</p>
  
  <pre><code>docker run -c=20 -i -t  ubuntu:latest /bin/bash
  </code></pre>
  
  <p>I tried to use <code>-c</code> flag to control CPU usage and maximize it in 50 %. When I am running <code>md5sum /dev/urandom</code> inside container, it use up 100 % CPU in host machine.</p>
