  <name>Containers Escape</name>
  <author>Z. Cliffe Schreuders</author>
  <description>An "escape room" -- you need to find a way into then escape to root a docker container and a chroot container. Hints: the flags are stored in /root/ on the two VMs but you first need to find your way in, and then escape confinement. Good luck!</description>
