[ale] Would you mind critiquing a container build HOWTO?

[Derek Carter]

   I think one problem is a misunderstanding of how `systemctl` works, 
it requires that you have your entire OS be running under systemd as an 
init system (pid 1).

A container should just be doing a single process.

This  means that you want to just do a CMD of that single process in 
your Dockerfile.

If you need more logic than that you have to write your own entrypoint 
script and then call that.


Here's a simple example derived from yours:
