CKA EXAM QS-1 2025

1- Create a new Horizontal PodAutoscale (HPA) named apache-server in the autoscale namesapce.

2-This HPA must target the existing Deployment called apacheserver in the autoscale namespace.

3-Set the HPA to aim for 50% CPU Usage per pod. Configure it to have at least 1 pod and no more than 4 Pods. Also, Set the downscale stabilization window to 30 Seconds.

Answer: Got to kubernetes Website and search and click on horizontal-podautoscale-walkthrough and copy below menifiest and deploy and do practice

https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscalewalkthrough/

===========================================================

Step 1: Create HPA

kubectl autoscale deployment apacheserver --cpu-percent=50 --min=1 --max=4 -n autoscale --name=apache-server

Step 2: Edit HPA to set the stabilization window

kubectl edit hpa apache-server -n autoscale

behavior:

scaleDown:

stabilizationWindowSeconds: 30

:wq

Final verification:

kubectl top pods ==> to check CPU utilization:

kubectl get hpa -n autoscale

kubectl describe hpa apache-server -n autoscale
