I disagree with the premise that using Docker to run individual processes is "wrong". Phusion is doing a disservice by suggesting as such. This is not the premise of the article. The premise is that someone goes 'from ubuntu; apt-get install memcache; cmd ["memcached"]' and thinks everything is going to be alright, when in reality they've just set up a rather buggy system. If you're absolutely certain your app is going to be fine running as the sole (PID1) process in the container, then this article has no problem with that. It just says that if you're going to run something you've got from apt-get, then chances are, your system is going to have to be a little more like a Debian system.
