title: Error with Jenkins ECS and EFS
body: <p>I'm trying to use Jenkins deploy to ECS with EFS. (/var/jenkins_home is mounted)</p>
  
  <p>It seems all fine except when I deploy a service I get following error in the log:</p>
  
  <pre><code>touch: cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied
  Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
  No newer events found at the moment. Retry.
  </code></pre>
  
  <p>Is there a way to fix this issue so I have enough permissions on <code>/var/jenkins_home</code>?</p>
