我是 Kubernetes 新手。我有一个用 go 语言编写的应用程序，它有一个/live端点。我需要根据 CPU 配置运行规模服务。如何根据 CPU 配置实现 HPA（水平 pod 自动缩放）。有人能帮我吗？谢谢！下面是/live端点的代码
router.Get("/live", netHttp.HandlerFunc(
func(w netHttp.ResponseWriter, r *netHttp.Request) {
http.NewHandler(pg).ServeHTTP(w, r)
},
))
下面是服务和部署代码：
apiVersion: v1
kind: Service
metadata:
name: simple-service-webapp-service
labels:
app: simple-service-webapp
spec:
ports:
- port: 8080
name: http
selector:
app: simple-service-webapp
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: simple-service-webapp-v1
labels:

下面是我应用的 hpa 配置：
kubectl autoscale deployment simple-service-webapp-v1 --cpu-percent=50 --min=1 --max=5
kubectl get hpa
