The path for engineers who want to own and operate Kubernetes clusters at a production level. Built on top of the Common Core, this learning path takes you from cluster installation and architecture to advanced security, networking, and troubleshooting , everything the Certified Kubernetes Administrator exam expects you to master.

What you’ll learn:

  • Cluster architecture & installation: Deep dive into control plane internals, installing clusters with kubeadm, node maintenance, upgrades, and etcd backup and restore
  • Workloads & scheduling: ConfigMaps, Secrets, resource management, DaemonSets, StatefulSets, Jobs, autoscaling, and advanced scheduling with taints, tolerations, and affinity rules
  • Services & networking: Service types, DNS, Ingress, the Gateway API, NetworkPolicies, and cluster networking fundamentals (CNI, iptables, IPVS)
  • Storage: Volumes, PersistentVolumes, PersistentVolumeClaims, and StorageClasses with dynamic provisioning
  • Security & auth: Service accounts, authentication, TLS certificates, kubeconfig, RBAC, security contexts, image security, admission controllers, and Pod security standards
  • Observability & troubleshooting: Logging, monitoring, and a structured troubleshooting methodology for nodes, Pods, and networking

Who is this for?

Platform engineers, DevOps practitioners, and SREs who deploy and maintain Kubernetes infrastructure. If your job involves keeping clusters healthy, securing workloads, and debugging production issues, this is your path.

Prerequisites: Complete the Common Core path first , this path builds directly on those foundations.

Course structure:

8 sections across 30+ modules, covering every domain of the CKA exam curriculum. Each lesson includes explanations, real YAML manifests, kubectl commands, and hands-on exercises in a live cluster.
