title: How do I create a directory in a Docker container that won't start?
body: <p>I have a Docker container (not image) that crashes when I try to start it.  The Docker logs show that it is failing because and Apache2 conf file can't find a directory (/var/www/html/log/ - this is the result of me trying to get SSL setup and forgot to create this directory after I referenced it in the 000-default.conf file and restarted Apache).</p>
  
  <p>How do I create this directory in the container without having to start the container itself?</p>
