创建工作负载

使用构建的hpa-example镜像创建无状态工作负载，Pod数为1。镜像地址与上传到的SWR仓库有关，需要替换为实际取值。

kind: DeploymentapiVersion: apps/v1metadata:  name: hpa-examplespec:  replicas: 1  selector:    matchLabels:      app: hpa-example  template:    metadata:      labels:        app: hpa-example    spec:      containers:      - name: container-1        image: 'hpa-example:latest'   # 替换为您上传到SWR的镜像地址        resources:          limits:                      # limits与requests建议取值保持一致，避免扩缩容过程中出现震荡            cpu: 500m            memory: 200Mi          requests:                                cpu: 500m            memory: 200Mi      imagePullSecrets:      - name: default-secret

创建一个端口号为80的服务。

kind: ServiceapiVersion: v1metadata:  name: hpa-examplespec:  ports:    - name: cce-service-0      protocol: TCP      port: 80      targetPort: 80      nodePort: 31144  selector:    app: hpa-example  type: NodePort

为工作负载和服务创建一个调度策略，并将其部署到cluster01和cluster02两个集群，使用权重拆分的方式部署，每个集群的权重为1，以保证两个集群的相同优先级。
