Horizontal Pod Autoscaling (HPA) is only supported by NF testnf-du-large.

Follow the below steps to enable it.


The following HPA content aligns with Kubernetes version v1.23+. For lower versions, please follow this guide https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/horizontal-pod-autoscaler-v1/#HorizontalPodAutoscalerSpec.

  maxReplicas: 2  
  minReplicas: 1
  - resource:      
      name: cpu      
        averageUtilization: 20        
        type: Utilization    
    type: Resource  
  • Please make sure the selected nodepool where testnf-du-large would be onboarded has at least 2 nodes, otherwise the new scaled-up pod would be in pending status.

  • Follow TestNF DU Large Onboard and Instantiation Page to instantiate testnf-du-large and select the prepared values.yml.

  • Once testnf-du-large pod is running, you could use cyclictest tool in the testnf-du-large pod to increase the load and you will see a new pod is created.
