To test this functionality create HPA for the function by applying HPA for example:
apiVersion: autoscaling/v1
kind: HorizontalPodAutoscaler
metadata:
name: <func_name>
spec:
maxReplicas: 10
minReplicas: 5
scaleTargetRef:
apiVersion: serverless.kyma-project.io/v1alpha2
kind: Function
name: demo
targetCPUUtilizationPercentage: 50
or use kubectl to do that:
kubectl autoscale function <func_name> --cpu-percent=50 --min=5 --max=10
of course you can use KEDA ScaledObject or any Kubernetes based scaler
example function:
apiVersion: serverless.kyma-project.io/v1alpha2
kind: Function
metadata:
name: demo
labels:
foo: bar
spec:
runtime: nodejs14
source:
inline:
dependencies: ""
source: |
module.exports = {
main: function(event, context) {
return 'Hello World'
}
}
replicas: 2
