This resource is designed to help with the preparation for the exam as a „Certified Kubernetes Administrator“ (CKA).

The exam for the CKA is a supervised hands-on online exam you can conduct at home on your computer within a time frame of three hours. The exam application will provide you with a Linux console and a single tab web browser that is restricted to the domain, Therefore, one part of the preparation consists of learning how to quickly find information on

However, knowing well, will not be sufficient: three hours might seem a long time for an exam, but it is cramped with tasks that take their time to accomplish. Therefore, you should be familiar with all the topics of the exam curriculum, to get quickly through.

CKA Labs

We have created following CKA Labs series that does not require you to install any Kubernetes infrastructure. Instead, we run all the labs on the Katacoda Kubernetes Playground, However, the labs should work on other Kubernetes infrastructure, if needed.

The following Kubernetes labs are available:

Following chapters are planned:

  • Custom Resource Definition
  • Helm Charts
  • Kubernetes Security Policies and Roles
  • (Optional) Kubernetes Federation? There are no labs found on LSF458 on that topic.
  • (Optional) Installation via kubeadm revisited

Let us head towards the Certified Kubernetes Administrator Certification…
