Published by O'Reilly Media, Inc.

Advanced content levelAdvanced

In-depth and hands-on practice

  • Demonstrate competency to perform the responsibilities of a Kubernetes application developer
  • Solve real-world Kubernetes problems in a hands-on command-line environment
  • Effectively navigate and solve questions during the CKA exam

The ability to administer and monitor a Kubernetes cluster is in high demand. In response, the Cloud Native Computing Foundation (CNCF) developed the Certified Kubernetes Administrator (CKA) certification to establish an operator’s credibility and value in the job market to confidently work in a Kubernetes environment. The CKA certification exam is different from the typical multichoice format of other certifications. It’s completely performance-based and requires deep knowledge of the tasks at hand under immense time pressure. Are you ready to pass the test on the first go?

Join expert Benjamin Muschko to explore all the topics covered in the redesigned 2020 CKA exam curriculum and fully prepare to ace the test. You’ll also hear Benjamin’s personal experience preparing for all aspects of the exam.

What you’ll learn and how you can apply it

By the end of this live online course, you’ll understand:

  • When and how to apply Kubernetes concepts to design, install, configure, and manage a production-grade cluster
  • Objectives, abilities, and tips and tricks (like time management, navigating the exam environment, and the type of questions to expect) needed to pass the CKA exam
  • The ins and outs of the kubectl command-line tool

And you’ll be able to:

  • Demonstrate competency to perform the responsibilities of a Kubernetes application developer
  • Solve real-world Kubernetes problems in a hands-on command-line environment
  • Effectively navigate and solve questions during the CKA exam

This live event is for you because...

  • You’re an administrator of a Kubernetes cluster and want to deeply understand Kubernetes concepts and techniques.
  • You want to learn the basics of Kubernetes by solving hands-on problems.
  • You want to become a Certified Kubernetes Administrator.
