Docker for CTFs (Application Virtualization)

Welcome back, everyone!

In today's video, we continue our discussion of virtualization with a focus on application layer virtualization and specifically a discussion of how to set up Docker, one of the more common application virtualization tools. We start with some history and go through the setup, but the more interesting part of the video in my opinion is applying this concept to a real scenerio. The final part of the video is taking this virtualization concept and applying it to a CTF problem: we talk about how to use docker for CTF problems, how to set up containers for CTF problems and ultimately how to challenge students or competitors with a lightweight, portable and easy to use containerization software.

If you've ever wanted to run a CTF, after watching the CTFd setup video you'll probably want to watch this. Containers are how most CTF coordinators run their problems on the backend. Docker provides a lightweight and flexible means to transfer challenges around and ensure compatibility. Docker also provides a great means to ensure version control and testing for developers, as well as standardize executable components and operating system controls as they deploy tools into foreign networks. We cover a variety of stuff here, but it is ultimately high-level. Hope you get something from it!
