HPA configuration

Kruise workloads, such as CloneSet, Advanced StatefulSet, UnitedDeployment, are all implemented scale subresource, which means they allow systems like HorizontalPodAutoscaler and PodDisruptionBudget interact with these resources.

Example​

Just set the CloneSet's type and name into scaleTargetRef:

apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
# ...
spec:
  scaleTargetRef:
    apiVersion: apps.kruise.io/v1alpha1
    kind: CloneSet
    name: your-cloneset-name

Note that:

  1. The HPA's namespace should be same as the namespace of your CloneSet.
  2. The apiVersion in scaleTargetRef should be same as the apiVersion in your workload resource, such as apps.kruise.io/v1alpha1 or apps.kruise.io/v1beta1. It depends on which version you are using for those workloads that have multiple versions, such as Advanced StatefulSet.
