Kubernetes CKS Full Course Theory + Practice + Browser Scenarios

Video Description

Certified Kubernetes Security Specialist (CKS) preparation! !!! USE Ubuntu 24.04 instances instead of the 20.04 shown in the video !!! This course does not include the 2024 changes and missing topics are: Cilium, PodSecurityStandards and SBOM. But these are included on https://killer.sh/cks and https://killercoda.com/killer-shell-cks. I will present each CKS topic in a simple and visual way. We'll run through various practical hands-on challenges. You'll setup own CKS cluster in which you'll learn, simple install scripts are provided. Instead of creating your own cluster you can also use the in-browser playground for mostly everything: https://killercoda.com/killer-shell-cks/scenario/playground. There are additional in-browser interactive scenarios to further study and harden your knowledge!

For most topics you'll need some time to implement the scenarios yourself. Also breaks (hours or even days) between sections/topics should be advised to prevent brain implosion :) You should already have some Kubernetes Administrator knowledge before attending this course. And if you like to attend the real CKS exam you need to hold a valid CKA certification. But I also do some recap of CKA knowledge at the beginning, so no worries if your knowledge is a bit stale.
