A final-revision summary for the CKA. Study aid only - the exam is hands-on, so practise in a real cluster.
The format

kubectl speed tips

|---|---|
alias k=kubectl | Saves keystrokes on every command |
--dry-run=client -o yaml | Scaffold YAML instead of writing it |
kubectl explain | Field reference without leaving the terminal |
kubectl get/describe/logs | Fast diagnosis for troubleshooting |
| Set a default namespace | Avoid repeating -n |
