This intensive, hands-on course prepares learners to pass the Certified Kubernetes Administrator (CKA) exam and become confident Kubernetes administrators. You’ll build clusters (kind/minikube/k3s and kubeadm), deploy and scale real applications, implement networking and storage, enforce security with RBAC and pod controls, and diagnose failures using logs, events, and component-level debugging. Every module contains guided labs, challenge exercises, and timed practical tasks that mirror the CKA performance format.

Target Audience

• System administrators, DevOps engineers, and SREs moving into Kubernetes operations

• Developers who manage runtime environments and want infra skills

• Candidates preparing specifically for the CKA exam

• Basic container knowledge (images/containers).

• Access to a machine or cloud account capable of running Docker/VMs.
  (Full prerequisite checklist is provided in the course materials.)

Module-by-Module Breakdown

Module 1 — Foundations & kubectl

What you’ll learn: kubectl fundamentals, kubeconfig contexts, namespaces, resource manifests, and API discovery.
Hands-on labs: Create namespaces, switch contexts, inspect and patch resources, and explore the Kubernetes API.
Assessment: Practical quiz — 10 CLI tasks (timed).

Module 2 — Cluster Architecture & kubeadm

What you’ll learn: Control plane components, kubelet, container runtimes, kube-proxy, kubeadm init/join, upgrades, and basic HA concepts.
Hands-on labs: Build a 2-node kubeadm cluster, inspect manifests in /etc/kubernetes, perform a control plane upgrade in a lab.
Assessment: Lab exercise — initialize and join nodes, document component status.

Module 3 — Workloads & Scheduling

What you’ll learn: Pods, Deployments, ReplicaSets, DaemonSets, Jobs/CronJobs, probes, resource requests/limits, affinity/taints/tolerations.
Hands-on labs: Create deployments with readiness/liveness probes, simulate pod failures, perform rollouts and rollbacks.
Assessment: Timed practical — recover a failing deployment and implement autoscaling.

Module 4 — Services & Networking

What you’ll learn: Pod networking basics, Service types (ClusterIP/NodePort/LoadBalancer), Endpoints, Ingress controllers, CoreDNS, and NetworkPolicy.
Hands-on labs: Deploy an Ingress controller and app, write NetworkPolicy to restrict traffic, debug DNS problems.
Assessment: Networking troubleshooting mini-exam (DNS NetworkPolicy tasks).

Module 5 — Storage

What you’ll learn: PV/PVC lifecycle, StorageClass, dynamic provisioning, volume types, access modes, reclaim policies.
Hands-on labs: Create StorageClasses and dynamic PVCs, move data between pods, troubleshoot volume mount problems.
Assessment: Practical exercise — provision persistent storage and validate failover behavior.

Module 6 — Security & RBAC

What you’ll learn: Roles, RoleBindings, ClusterRoles, ServiceAccounts, Secrets, ConfigMaps, Pod Security Admission and best practices for least privilege.
Hands-on labs: Create least-privilege roles, lock down access to resources, audit service account permissions.
Assessment: RBAC challenge — restrict an app so only a specific service account can access secrets.

Module 7 — Maintenance & Troubleshooting

What you’ll learn: Node lifecycle (cordon/drain), monitoring basics (kubectl top), reading logs and events, debugging kubelet/kube-proxy/API server, and common failure patterns.
Hands-on labs: Induce node and pod failures, gather logs and events, diagnose root causes and recover services.
Assessment: Full troubleshooting lab (timed) covering multiple simultaneous faults.
