CKA - Certified Kubernetes Administrator Intensive Training
Beginner · 5 half days or flexible as in-house training · In-House
This workshop prepares you specifically for the Certified Kubernetes Administrator (CKA) exam from the Linux Foundation / CNCF – the internationally recognized certification for professional Kubernetes administration.
Important: The exam and certification are not part of this course and are not included in the seminar price. In cooperation with the Linux Foundation, we offer you the option to book and take the exam separately.
The training covers all five official exam domains in full: Cluster Architecture, Installation & Configuration (25%), Workloads & Scheduling (15%), Services & Networking (20%), Storage (10%) and Troubleshooting (30%). The curriculum is aligned with the 2026 version – including Helm, Kustomize, Gateway API, CRDs and Operators.
Agenda
Kubernetes Introduction & Architecture
Every participant gets their own test environment in the cloud. All concepts are explained using clear examples and can be tried out directly in more than 30 hands-on exercises in the classroom.
- Overview of the Kubernetes ecosystem and the Cloud Native Computing Foundation (CNCF)
- Cluster architecture: control plane (API server, etcd, scheduler, controller manager) and worker nodes (kubelet, kube-proxy, container runtime)
- Container runtimes: containerd, CRI-O and the Container Runtime Interface (CRI)
-
kubectl mastery: imperative vs. declarative approach, aliases, shortcuts and
--dry-run=client -o yaml - Pods: creating, configuring and managing
- Commands & args in pods
- Multi-container pods: sidecar, init and ambassador patterns
- Probes: liveness, readiness and startup
- Labels and selectors
Workloads & Scheduling
- ReplicaSets: self-healing and scaling
- Deployments: rolling updates, rollbacks and revision history
- DaemonSets: deploying node-wide workloads
- StatefulSets: running stateful applications
- Jobs and CronJobs: one-off and scheduled tasks
- ConfigMaps and Secrets: cleanly separating configuration from images
- Automatic scaling with the Horizontal Pod Autoscaler (HPA)
- Node selector, node affinity and pod affinity
- Taints and tolerations: placing and repelling workloads deliberately
- Resource requests and limits: controlling pod admission and scheduling
Networking & Ingress
- The Kubernetes network model: pod-to-pod communication and cluster networking
- Overview of CNI plugins: Calico, Flannel, Cilium
- Services in detail: ClusterIP, NodePort, LoadBalancer and ExternalName
- Understanding service discovery and endpoints
- CoreDNS: configuration and troubleshooting
- Configuring ingress controllers and ingress resources
- Gateway API: the modern successor to Ingress – HTTPRoute and Gateway resources
- Network policies: ingress and egress rules following the least-privilege principle
Storage
- Overview of volumes and their types
- Static persistence: creating and using PersistentVolumes (PV) manually
- Dynamic persistence: StorageClasses and automatic volume provisioning
- PersistentVolumeClaims (PVC): access modes and reclaim policies
- Storage in StatefulSets: volumeClaimTemplates
Security & Access Control
- Overview of the Kubernetes security model
- Authentication: certificates, ServiceAccounts and Certificate Signing Requests (CSR)
- Authorization with RBAC: Roles, ClusterRoles, RoleBindings and ClusterRoleBindings
- Security contexts: restricting permissions at pod and container level
- Secrets management with Sealed Secrets (bonus)
Cluster Operations & Maintenance
- Monitoring & logging: kubectl logs, kubectl top, events and metrics-server
- Prometheus: collecting and visualizing cluster metrics
- Node maintenance: cordon, drain and uncordon
- Cluster lifecycle management: Kubernetes upgrade with kubeadm (control plane and worker nodes)
- etcd backup and restore: securing the cluster state
- Highly available control plane: stacked etcd vs. external etcd topology
Tooling & CKA Exam Preparation
- Helm: installing and upgrading charts and structuring your own charts
- Kustomize: managing environment-specific configurations with overlays (bonus)
- Exam format and time management: structure and procedure of the CKA exam
- Using the permitted resources efficiently: kubernetes.io/docs, helm.sh/docs, gateway-api.sigs.k8s.io
- Tips & tricks: kubectl aliases, switching contexts, generating YAML templates quickly
- Mock exam: simulated exam under realistic conditions on the command line
- Evaluation and individual recommendations for further exam preparation
What you should know
We provide you with a fully preconfigured lab environment with real Kubernetes clusters for the workshop – you don't need to install anything in advance.
If you'd still like to warm up, we recommend:
👉 Install kubectl and set up a local cluster with minikube or kind
👉 Work through the official Kubernetes tutorial at kubernetes.io/docs/tutorials (approx. 2 hours)
The course “CKA - Certified Kubernetes Administrator” is aimed at Beginner.
