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: Deployment
apiVersion: apps/v1
metadata:
  name: hpa-example
spec:
  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: Service
apiVersion: v1
metadata:
  name: hpa-example
spec:
  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。

apiVersion: policy.karmada.io/v1alpha1
kind: PropagationPolicy
metadata:
  name: hpa-example-pp
  namespace: default
spec:
  placement:
    clusterAffinity:
      clusterNames:
      - cluster01
      - cluster02
    replicaScheduling:
      replicaDivisionPreference: Weighted
      replicaSchedulingType: Divided
      weightPreference:
        staticWeightList:
        - targetCluster:
            clusterNames:
            - cluster01
          weight: 1
        - targetCluster:
            clusterNames:
            - cluster02
          weight: 1
  preemption: Never
  propagateDeps: true
  resourceSelectors:
  - apiVersion: apps/v1
    kind: Deployment
    name: hpa-example
    namespace: default
  - apiVersion: v1
    kind: Service
    name: hpa-example
    namespace: default
