HPA Review

Overview

HorizontalPodAutoscaler (HPA) has been configured for RPC nodes to automatically scale based on CPU and memory usage.

HPA Configuration

Target

StatefulSet: besu-rpc
Namespace: besu-network

Scaling Parameters

Min Replicas: 2
Max Replicas: 10
CPU Target: 70% utilization
Memory Target: 80% utilization

Scaling Behavior

Scale Up: 100% increase or 2 pods per minute (whichever is higher)
Scale Down: 50% decrease per minute
Stabilization Window: 300 seconds (scale down), 0 seconds (scale up)

Validation

Run the validation script:

./scripts/validation/validate-hpa.sh

Application

Apply HPA:

kubectl apply -f k8s/base/rpc/hpa.yaml

Testing

Generate load on RPC endpoints and verify HPA scales pods based on CPU/memory usage.

Requirements

Metrics server must be installed in the cluster
Resource requests and limits must be set on pods
HPA requires metrics API to be available
