What prerequisites do I need for CKA certification?

Formal Prerequisites: None (the CKA exam has no official requirements). Recommended Skills for Optimal Success: Kubernetes Basics: You should already know Pods, Deployments, and Services Linux Administration: Confident use of systemctl, journalctl, Bash, text editor (vim or nano) Networking Basics: Basic understanding of IPs, ports, DNS (no expert knowledge needed) You Don't Need to Be a Cluster Admin: This workshop covers all CKA topics from the ground up, including cluster installation with kubeadm, etcd backups, CNI configuration, and RBAC. If you've only worked with Kubernetes as a developer so far, you'll be ready for the exam after 2-4 weeks of hands-on practice (workshop + Killer.sh exercises). Optional: If you have no Kubernetes experience yet, we recommend Kubernetes Introduction (DW2) or CKAD Application Developer (DW5) as preparation.

What is the difference between CKA and CKAD?

CKA (Cluster Administrator) focuses on cluster operations and infrastructure: cluster installation (kubeadm), upgrades, etcd backups, node management, CNI configuration, troubleshooting (NotReady nodes, kubelet logs). CKAD (Application Developer) covers application development: Pods, Deployments, Services, ConfigMaps, Secrets, Helm, Observability (logging, monitoring). Which certification for whom: CKA: Platform Engineers, Cluster Administrators, SRE (infrastructure focus), DevOps teams operating clusters themselves CKAD: Application Developers, DevOps Engineers (CI/CD focus), SRE (app focus) Typical Learning Path: Administrators and Platform Engineers start with CKA (infrastructure), then CKS (security). Developers start with CKAD (applications), then optionally CKA for deeper understanding. We offer all three as workshops: CKAD Application Developer (DW5) and CKS Security Specialist (DW7).

How much time do I need for CKA preparation?

With Kubernetes experience: 4-6 weeks of intensive preparation (10-15 hours/week). Without prior knowledge: 8-12 weeks. Our 4-day workshop significantly reduces self-study time: You cover all 5 exam domains in a structured way (instead of fighting through fragmented online tutorials) You receive best practices for cluster installation, etcd backups, and troubleshooting After the workshop: 2-3 weeks of follow-up with Killer.sh and your own exercises typically suffice Essential for preparation: Killer.sh sessions (2×36h, included in CKA voucher), intentionally harder than the real exam Hands-on practice with real clusters (KodeKloud Labs, your own VMs, or cloud environments) Train documentation usage (allowed during exam: kubernetes.io, GitHub, Helm Docs) ROI: Certified CKA administrators solve cluster problems systematically (shorter MTTR), avoid preventable outages, and reduce dependencies on external consultants.

Is the CKA exam voucher included in the workshop?

No, the CKA exam voucher is not included in the workshop price. You purchase it after the workshop directly from the Linux Foundation (approx. $395 USD). Included in the voucher: 1x CKA exam (2 hours, online, proctored) 1x free retake attempt 2x Killer.sh sessions (36 hours of access to the exam simulator each) The voucher is valid for 12 months after purchase, so you schedule the exam date flexibly. In the workshop, we prepare you specifically for both the exam and the simulator so you can make the most of the voucher.

Is Killer.sh harder than the real CKA exam?

Yes, Killer.sh is intentionally harder than the real CKA exam. If you pass Killer.sh (or get close to 66%), you're very well prepared for the real exam. Why harder: Time limit is tighter (approx. 5 min per task vs. 6-8 min in the real exam) Tasks are more complex (multi-step scenarios, more troubleshooting) Intentionally designed as a "stress test" What you practice in Killer.sh: Cluster installation with kubeadm (from scratch, no templates) Create and restore etcd backups with TLS certificates Debug NotReady nodes (kubelet logs, systemctl, CNI issues) Configure RBAC permissions (Roles, ClusterRoles, Bindings) Create Network Policies for pod isolation Access: Killer.sh is included in the CKA Exam Voucher (approx. $395 USD), you get 2 sessions of 36 hours each. You typically use the first session 1-2 weeks after the workshop, the second shortly before the exam.

What can I do after the CKA workshop? What's next?

After the workshop, you can independently install, operate, and troubleshoot Kubernetes clusters: cluster installation with kubeadm, zero-downtime upgrades, etcd backups, RBAC configuration, Network Policies, storage management. You understand cluster architecture deeply and can systematically fix NotReady nodes, CNI issues, and kubelet errors. In your daily work, you use this for: Production-grade cluster administration (backups, upgrades, monitoring) Troubleshooting (reduce MTTR, prevent outages) Security hardening (RBAC, Network Policies, Pod Security Standards) Team onboarding (share best practices) Next Steps: CKS Security Specialist (DW7): Security hardening (Pod Security Standards, image scanning, runtime security, audit logging), ideal for production environments Observability & Monitoring (DW10): Prometheus, Grafana, Loki, OpenTelemetry, completes your cluster operations skills Practice: 2-3 weeks of Killer.sh + your own cluster exercises → take the CKA exam

09:00 - 09:00💭 Questions & Answers

09:00 - 09:30

Introduction to CKA

Get a structured overview of the CKA certification: exam format (2 hours, 15-20 tasks, 66% passing score), the 5 exam domains (Troubleshooting 30%, Cluster Architecture 25%, Services & Networking 20%, Workloads & Scheduling 15%, Storage 10%), and practical learning strategies. Understand how to optimize your exam time and what skills the certification demonstrates.

09:30 - 10:00

Understanding Kubernetes Architecture (Cluster Architecture 25%)

Understand how a Kubernetes cluster is structured and which components work together. The control plane manages all decisions (API server as command center, etcd as data store, scheduler for placement), while worker nodes do the actual work. This knowledge is essential for quickly isolating errors and understanding where problems can occur.

Kubernetes

10:00 - 10:30

Container Runtimes in the Cluster

Kubernetes uses various container runtimes like containerd or CRI-O to actually start containers. Learn how these runtimes are integrated, how to switch between them, and how to identify runtime-specific issues. This is especially important when containers won't start or terminate unexpectedly.

10:30 - 11:30

Working Efficiently with kubectl

kubectl is your primary tool for cluster management. Learn how to quickly retrieve information, debug problems, and edit resources directly. Especially important: when is a fast command line shortcut worth it, and when should you work with YAML files? This decision saves valuable minutes during the exam.

11:30 - 12:00

Managing Multiple Clusters Simultaneously

In practice and during the exam, you frequently work with multiple clusters simultaneously (e.g., test, staging, production). Learn how to seamlessly switch between different clusters while maintaining overview. You'll also understand how access configuration works and what to do when authentication fails.

12:00 - 13:00🥪 Lunch Break

13:00 - 14:30

Building Your Own Cluster from Scratch (Cluster Architecture 25%)

Build a production-ready Kubernetes cluster from scratch. Learn how individual components are initialized, how worker nodes join, and how the network plugin enables pod communication. By the end, you'll understand exactly what happens during cluster startup and can systematically fix installation issues.

kubeadm

14:30 - 15:30

Updating Clusters Without Downtime (Cluster Architecture 25%)

Kubernetes versions change regularly. Learn how to upgrade your cluster without downtime. Understand which steps are needed in what order, how to temporarily take nodes out of service, and how to ensure all applications remain available. This skill is essential for production environments.

15:30 - 16:00

Backing Up and Restoring Cluster Data (Cluster Architecture 25%)

The entire cluster state resides in etcd - all deployments, services, secrets. Learn how to create regular backups and restore your cluster in an emergency. This skill can mean the difference between a brief outage and total data loss in production. In the exam, this is a frequent and high-scoring topic.
