We have two events - you can play in both if you like.

From Friday to Sunday, we have a non-competitive Learning CTF, where you can go through last year's Kubernetes CTF scenario, referring to a cheat sheet whenever you want. This runs from Friday 12:00 to Sunday 12:00. We'll be in the contest area to support you during:

Friday: 12:00-17:00 Saturday: 10:00-17:00 Sunday: 10:00-12:00

On Saturday only, you can play in the competitive Kubernetes CTF challenge, where teams (of one or more) can build and test their skills. Each team is given access to a single Kubernetes cluster that contains a set of challenges. This runs from 10:30am to 5:30pm on Saturday. The competitive CTF is an in-person experience. To register for the competitive CTF, you must come to the contest booth at DEF CON.
