Kubernetes Administrator CKA

The Cloud Native Computing Foundation offers a certification program that allows users to demonstrate their competence in a hands-on, command-line environment.

Certification is a key step in that process, allowing certified application developers to quickly establish their credibility and value in the job market, and also allowing companies to more quickly hire high-quality teams to support their growth.



The Certified Kubernetes Administrator (CKA) program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation, to help develop the Kubernetes ecosystem through standardized training and certification.

The purpose of the Certified Kubernetes Administrator (CKA) program is to provide assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators. It is an online, proctored, performance-based test that requires solving multiple issues from a command line.

The Certification focuses on the skills required to be a successful Kubernetes Administrator in industry today. This includes these general domains and their weights on the exam:

  • Cluster Architecture, Installation & Configuration

  • Workloads & Scheduling

  • Services & Networking

  • Storage

  • Troubleshooting

Class Size

Maximum 5 participants.

Course Language

Please notice that the training and all training material is in English, as the exams are held exclusively in the english language.



Study Load

The program is built for experienced DevOps Engineers, System Administrators or Security Specialists with good knowledge of containers, docker and microservices. During classes the most important points will be demonstrated in labs, where the candidates can see how the theory can be applied to solve problems in a Kubernetes cluster.
However you will need about 20 hours to study the syllabus and at least 60-80 hours of practice, to reflect on the total material and solve exercises before the exams.


Exam Details

The online, proctored, performance-based test consists of a set of performance-based items (problems) to be solved in a command line and is expected to take approximately two (2) hours to complete.
