Now Available! You can bundle CKA with an annual THRIVE subscription to get access to more than 100 educational products, including Kubernetes Fundamentals (LFS258) and SkillCreds for only $595!

The Certified Kubernetes Administrator (CKA) program provides assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators.

Not sure where to start? You may consider reviewing our suggested CKA learning path.

EXAM SIMULATOR! Learners will now have access to an exam simulator, provided by Killer.sh, to experience the exam environment. You will have two exam simulation attempts (36 hours of access for each attempt from the start of activation). Simulation includes 20-25 questions (which are exactly the same for every attempt and every user (unlike those found on the actual exams) and graded simulation results.

PLEASE NOTE: Please see upcoming changes to the Certified Kubernetes Administrator (CKA) exam (changes NOT taking place prior to January 15, 2025). Bookmark the link and check back for the official release date.
