Question

You configured a HorizontalPodAutoscaler for a Deployment with a target of 50% average CPU utilization. Each pod has a CPU request of 200m. The Deployment currently runs 3 pods, and the metrics-server reports the pods are consuming 180m, 160m, and 200m of CPU respectively. Based on the standard HPA scaling algorithm, what will the HPA do?

Accepted Answer

Scale up to 6 replicas, because current average utilization is 90% and the target is 50%

Answer

Scale up to 4 replicas, because at least one pod exceeds the 50% target

Answer

Keep 3 replicas, because total CPU usage is below the sum of all requests

Answer

Scale down to 2 replicas, because average absolute CPU is under 200m
