Certified Kubernetes Administrator (CKA) Preparation 

Course & Training

Certified Kubernetes Administrator - Preparation Course (CKA) – 2 to 3 days.

The CKA certification is not only an important proof of skills around Kubernetes administration, it is also an exciting challenge as well as motivation to condense your knowledge and increase your skill. This 2 to 3 day course takes you a big step closer to passing the certification and guides you through exciting scenarios to better understand, operate and troubleshoot Kubernetes clusters.

Content:


A Kubernetes cluster environment with prepared scenarios is provided, which are worked through together. Important tools, resources, tips for preparation and strategies for finding solutions will be shown - not only for the exam, but also for the daily operation of Kubernetes.

- Pointing out the prerequisites and topics of the exam
- Going through the provided test environment
- Pointing out important auxiliary tools as well as tips during the course of the scenarios
- (vim, ssh, cat, >>, |, grep, watch, screen, shortcuts)
- Prepare command line environment
- Effective use of the documentation and kubectl help as well as kubectl explain
- Working through tasks together
- Explanation of the task by trainer
- Independent execution of the task
- Tips and assistance in solving the tasks
- Joint discussion of the solution
- Scenarios on the following topics are played through:
- (one scenario can cover several topics)
- Cluster architecture, installation and configuration
- Creating and managing Kubernetes clusters using kubeadm
- Cluster lifecycle management and upgrades
- Implementing and configuring a highly-available control plane
- RBAC (Role-Based Access Control)
- Extension interfaces (CNI, CSI, CRI)
- Custom Resource Definitions (CRD) and Operators
- Helm and Kustomize for cluster components
- Workloads and scheduling
- Deployments, rolling updates and rollbacks
- ConfigMaps and Secrets
- Workload autoscaling
- Pod admission and scheduling (limits, node affinity, etc.)
- Storage classes and dynamic volume provisioning
- Volume types, access modes and reclaim policies
- Persistent Volumes and Persistent Volume Claims
- Servicing and networking
- Connectivity between Pods and Services
- ClusterIP, NodePort, LoadBalancer service types and endpoints
- Defining and enforcing Network Policies
- Gateway API and Ingress controllers
- CoreDNS
- Troubleshooting
- Troubleshoot clusters and nodes
- Troubleshoot cluster components
- Monitor cluster and application resource usage
- Manage and evaluate container output streams
- Troubleshoot services and networking
- Review of the strict rules and preparation of the workstation for remote testing
- Identify additional preparation, learning, and practice resources

Even though the course is primarily focused on the CKA exam, it condenses important content that will be of great benefit to your day-to-day work operating and administering Kubernetes clusters.

Delineation:
1. emphasis is placed on not violating certification rules in any way: Effective questions of the official test will NOT be reported.
2. the course uses only self-developed scenarios that differ from the real exam in content and difficulty (tending to be slightly more difficult than the real exam).
3. the course does not guarantee in any way the passing of the real test and is in no way related to the organization behind the certification or the certification body.
4. the certification framework is regularly adjusted by the issuer and therefore it is essential for the participant to check it before actually taking it.
5. depending on the existing experience and skill (time pressure) in dealing with Kubernetes, containers and the command line, it requires additional learning and practice to pass the certification.


Disclaimer: The actual course content may vary from the above, depending on the trainer, implementation, duration and constellation of participants.

Whether we call it training, course, workshop or seminar, we want to pick up participants at their point and equip them with the necessary practical knowledge so that they can apply the technology directly after the training and deepen it independently.

Goal:

Participants will have a good overview of the exam topics, the possible structure of tasks, a skillful approach to solving them and will be able to assess where they should further deepen their knowledge as well as practice using the tools.


Duration:

 3 Days (Is individually adapted for in-house courses.)


Form:

A Kubernetes cluster environment will be provided with prepared scenarios which will be worked through together. Important tools, resources, tips for preparation and strategies for finding solutions will be shown - not only for the exam, but also for the daily operation of Kubernetes.


Target Audience:

System engineers, DevOps engineers or platform engineers who operate Kubernetes clusters, want to consolidate their knowledge, become more efficient in administering Kubernetes and complete the CKA certification.


Requirements:

Attendees will bring a basic understanding of the following topics:

\- Creating and removing pods using kubectl on a Kubernetes cluster
\- Defining deployments and services using YAML and applying them via kubectl
\- Basic Linux administration knowledge (systemd, network configuration, filesystem)
\- Basic knowledge of networking (TCP/IP, network masks, ports, establishing HTTP connections, etc.)
\- Basic knowledge Linux command line (bash, cp, mv, cd, ls, ssh, cat, echo...)


Preparation:

 Every participant will receive a questionnaire and a preparation checklist after registration. We provide a comprehensive laboratory environment for each participant, so that all participants can directly implement their own experiments and even complex scenarios.

More about the CKA Certification



The Certified Kubernetes Administrator (CKA) certification by the Cloud Native Computing Foundation (CNCF) is a hands-on, performance-based exam that tests real Kubernetes administration tasks in a live environment. It is a recognized credential for engineers and administrators who install, configure, operate and troubleshoot Kubernetes clusters.




History


Kubernetes was released as an open-source project by Google in 2014, based on their internal system Borg. In 2015, Google and other companies founded the Cloud Native Computing Foundation (CNCF) , which adopted Kubernetes as its first project and has coordinated its development ever since.


The CKA certification was introduced by the CNCF in 2016 – one of the very first Kubernetes certifications – to provide a standardized, practical credential for Kubernetes administration skills. Unlike multiple-choice exams, the CKA requires candidates to solve real tasks in a live Kubernetes environment. The curriculum is regularly updated and today covers topics such as cluster installation with kubeadm, high availability, networking with CNI plugins, and troubleshooting.


Today, the CKA is one of the most recognized and sought-after Kubernetes certifications worldwide, acknowledged by companies and recruiters as a reliable indicator of cluster administration competence. It also provides a solid foundation for advanced certifications such as the CKS (Certified Kubernetes Security Specialist).
