Certified Kubernetes Application Developer Crash Course (CKAD)

In-depth and hands-on practice for acing the exam

Benjamin Muschko

The ability to use, troubleshoot and monitor Kubernetes as an application developer is in high demand. In response, the Cloud Native Computing Foundation (CNCF) developed the Certified Kubernetes Application Developer (CKAD) certification to establish a developer’s credibility and value in the job market to confidently work in a Kubernetes environment. The exam is different from the typical multi-choice 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?

This practical course is designed to walk you through all the topics covered in the exam to fully prepare to pass the certification exam. The trainer and CKAD, Benjamin Muschko, will also share his personal experience with preparing for all aspects of the exam.

What you'll learn-and how you can apply it

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

  • When and how to apply Kubernetes concepts to manage an application
  • Objectives, abilities, and tips and tricks (like time management, navigating the exam environment, and the type of questions to expect) needed to pass the CKAD exam
  • The ins and outs of the kubectl command line tool

And you’ll be able to:

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