由于公司业务原因，需要的pod比较多，从0到300花费时间太长，所以给柯达增加时间段伸缩功能，晚上的0-100之间伸缩，白天在100-300之间伸缩

示例：

apiVersion: keda.sh/v1alpha1  
kind: ScaledObject  
metadata:  
  name: {scaled-object-name}  # ScaledObject 对象的名称  
  annotations:  
    minReplicaCountStart："07:00"    # 可选。代表minReplicaCount的开始时间  
    minReplicaCountEnd: "19:00"      # 可选。代表minReplicaCount的结束时间  
    minReplicaCountStr: "100"        # 可选。代表minReplicaCount的值，注，上面三个值都设置才生效  
spec:  
  scaleTargetRef:  
    其他内容略  

Kubernetes-based Event Driven Autoscaling

KEDA allows for fine-grained autoscaling (including to/from zero) for event driven Kubernetes workloads. KEDA serves as a Kubernetes Metrics Server and allows users to define autoscaling rules using a dedicated Kubernetes custom resource definition.

KEDA can run on both the cloud and the edge, integrates natively with Kubernetes components such as the Horizontal Pod Autoscaler, and has no external dependencies.

We are a Cloud Native Computing Foundation (CNCF) graduated project.
