title: Start cron and another process in single docker container
body: <p>I have a docker image that will start a foreground httpd process.  I also have some tasks that
  I'd like to run as cron jobs via crontab.</p>
  <p>Ideally I'd like to start httpd as a non root user, however, to also start cron, will require me to be root</p>
  <pre><code>FROM ubuntu:latest
  
  RUN apt-get update 
      &amp;&amp; DEBIAN_FRONTEND=noninteractive apt-get dist-upgrade -yq \
      &amp;&amp; apt-get install -y cron httpd
  
  # Do a bunch of other setup.....
  
  USER 1000
  
  #START PROCESSES....
  
  </code></pre>
  <p>The problem as I see it is that I cannot start cron as root, keep that process running and also start httpd as a foreground process.</p>
  <p>Is there some way to have both these processes started in one docker container?</p>
