The big picture: control plane & Pods
See how the control plane, nodes, and API server fit together — and why the Pod, not the container, is what you actually deploy.
Scheduling & troubleshooting
Turn a Pending or CrashLoopBackOff Pod into a fixed one by reading describe, logs, and events like a pro.
Networking & Services
Trace traffic all the way to your Pods through Services, Endpoints, and cluster DNS — and know why a stable ClusterIP matters.

Chapter 1 review — Core: architecture, scheduling & networking
Lab: Deploy, expose, and debug · 10-question check
Config & Secrets
Keep config out of your images: inject settings with ConfigMaps and Secrets, as env vars or mounted files, the way Kubernetes intends.
Storage & Volumes
Make your data outlive any Pod using Volumes, PersistentVolumes, PVCs, and StorageClasses for on-demand, durable storage.
Cluster lifecycle: kubeadm, etcd & upgrades
Master the heavily-weighted CKA admin domain: bootstrap clusters with kubeadm, run HA control planes, snapshot and restore etcd, and upgrade without downtime.

Extending the cluster: Helm, Kustomize, CRDs & operators
Package, template, and extend Kubernetes with Helm, Kustomize, CRDs, and operators — plus the CNI, CSI, and CRI interfaces new to the current exam.
RBAC & security: roles, bindings & least privilege
Lock down who can do what using Roles, ClusterRoles, RoleBindings, and ServiceAccounts — and learn why RBAC only ever grants, never denies.
Troubleshooting: a systematic debugging workflow
Own the exam's biggest domain with a repeatable kubectl workflow for failing Pods, NotReady nodes, broken control-plane components, and dead service paths.
