Know the goal of phase 4
Build, run, upgrade and repair a Kubernetes cluster, and deploy apps on it with the right network, storage and access rules.
| Item | Value |
|---|---|
| Exam | CKA — Certified Kubernetes Administrator |
| Format | Hands-on, 2 hours, kubernetes.io docs allowed |
| Domains | Troubleshooting 30 %, cluster architecture 25 %, services and networking 20 %, workloads and scheduling 15 %, storage 10 % |
| Price | about $445, one free retake, killer.sh simulator included |
Study with these sources
One main course with browser labs, the docs, and the simulator at the end.
| Source | Use it for |
|---|---|
| ★ CKA curriculum (CNCF) | The checklist |
| LFS158 Introduction to Kubernetes (free) | A first pass, 15 – 20 hours |
| ★ KodeKloud CKA course (Mumshad Mannambeth) | The main course: videos, browser labs, 3 mock exams |
| ★ Kubernetes docs | Learn to find things fast — your only help in the exam |
| ★ killer.sh | Two simulator sessions with the exam, harder than the real one |
| Kubernetes The Hard Way | Build a cluster by hand once, to really understand it |
| CKA Study Guide — Benjamin Muschko | The book |
| My summary | CKA |
Practise the right way
Speed with kubectl decides the exam. Practise every task until you do it without thinking.
alias k=kubectl
export do="--dry-run=client -o yaml"
k create deployment web --image=nginx --replicas=3 $do > web.yaml
k explain pod.spec.containers.livenessProbe
k config use-context lab- A home cluster with kubeadm (3 VMs) or k3s; rebuild it at least 3 times.
- Every week: one etcd backup and restore, one cluster upgrade, one broken node to fix.
- Killercoda CKA scenarios for short daily practice.
- killer.sh in the last 2 weeks.
Build the phase project
The app of phase 3 on Kubernetes at home: Deployment, Service, Ingress, ConfigMap and Secret, a PersistentVolume, resource limits, probes, and a NetworkPolicy.
Finish the phase
The phase is done when all of these are true.
- [ ] CKA passed.
- [ ] The home cluster runs the project app; manifests or a Helm chart on GitHub.
- [ ] Job applications started: 5 – 10 per week from month 6.
