title: What does UseContainerSupport VM parameter do?
body: <p>What does this option do in docker file?</p>
  
  <pre><code>ENTRYPOINT java -XX:+UseContainerSupport $JAVA_OPTIONS -jar /myapp.jar
  </code></pre>
  
  <p>Will the docker container start without this parameter?
  I checked <a href="http://www.batey.info/docker-jvm-k8s.html" rel="noreferrer">one article</a> which says </p>
  
  <blockquote>
    <p>enable memory support</p>
  </blockquote>
  
  <p>but it is still not clear to me.</p>
