Preparation for CKA/CKA

I’m constantly being asked, which resources I’ve used to prepare to CKA/CKAD exams.

That’s why I’ve prepared such list.

Theory:

• Courses on Linux Academy: CKA and CKAD. CKA course is pretty poor, practice is sparse. CKAD course here is much better.
• Kubernetes in Action by Marko Luksa the best book which Ive read on Kubernetes; author explain every topic in great detail. With second edition out content is up-to-date.
• CKAD prep course by Benjamin Muschko short but extensive course, great for CKAD preparation
• Theory in CKA-StudyGuide repo
• Official Kubernetes Documentation is a must for CKA/CKAD, especially since youre allowed to use it on exam.

  Practice:

• I’ve used Vagrant spinning up 3 VMs(master+2 workers), this was enough to simulate all the tasks on the exam.
• Kubernetes the hard way by Kelsey Hightower
• Practice for CKA by David-VTUK
• Practice for CKAD by Benjamin Muschko
• Practice for CKAD by dgkanatsios
• I was also using Pytests testinfra and kubetest to validate my work. Writing tests is time-consuming but you get a good understanding how examiner will validate your work and how important small details are(i.e. deploy to correct namespace)

Internet is full of tips/guides on how to pass CKA/CKAD exam so all that ones really need is time and desire to learn. And lots of practice.
