I am using HPA(HorizontalPodAutoscaling) along with custom metrics in kubernetes. I can scale my pod count according to my custom metrics value.
kind: HorizontalPodAutoscaler
apiVersion: autoscaling/v2alpha1
metadata:
name: sample-metrics-app-hpa
spec:
scaleTargetRef:
kind: Deployment
name: sample-metrics-app
minReplicas: 2
maxReplicas: 10
metrics:
- type: Object
object:
target:
kind: Service
name: sample-metrics-app
metricName: http_requests
targetValue: 100Is it possible to define multiple target value, for example if the http request hits 100 then the pod should scale by 10(min replica should be 2 for this), if it hits 1000, then the pod should scale by 20(min replica needs to be 10).
As I know it is not possible to achieve such result with HPA. Moreover, your configuration says that every 100 http requests hpa will add 1 more pod. Not 2 --> 10 at once, but again, 1-->2-->3 every 100 requests.
