CKS tips and takeaways Yay! I got my ‘CKS - Certified Kubernetes Security Specialist’ certification. It was quite a ride, as I had almost forgotten about it. You see, I had 2 goals this year: the GitOps homelab and CKS. I have done and learned a lot in the homelab, so much so that I had neglected the CKS a bit. I was under the impression that I had some time left when I was reminded by The Linux Foundation that I only had 4 weeks left to plan the exam (and potential retake). After those 4 weeks, the money my employer generously paid for me to get certified would be down the drain. So I applied myself and studied as hard as I could.
