Hi James I worked on this course a few years back. This predates docker, so I want to say we used a combination of some sort of jail, the correct privs, app armor, and of course isolated servers. :) It is actually running the commands on a real server, its just really locked down to the point of even removing some of the normal shell commands from the user that's running.
