Let's play around with Docker a bit more. We learn about the nsenter command, how kernel code execution allows escaping from docker and we look at Linux Kernel source code of getpid().
Let's figure out how Docker works! We will investigate docker by tracing the syscalls to find the Linux Kernel feature called Namespaces. We also learn about the different ones like process id, net...

We continue doing some Cheat Engine work to find the player's and camera's position. This will help us to implement a fly hack in a future episode.
