如何在Kubernetes中使用负载平衡器服务公开多端口

apiVersion: extensions/v1beta1
kind: Deployment
metadata: 
  name: deployment-name
spec:
  replicas: 1
  template:
    metadata:
      name: pod-name
      labels: 
        app: app-label
    spec:
      containers: 
      - name: container-name
      image: gcr.io/project-id/image-name
      resources:
        requests:
          cpu: 1
      ports:
      - name: port80
        containerPort: 80
      - name: port443
        containerPort: 443
      - name: port6001
        containerPort: 6001

然后我想创建一个服务,使pod能够侦听所有这些端口。我知道以下YAML文件用于创建在一个端口上侦听的服务:

apiVersion: v1
kind: Service
metadata: 
  name: service-name
spec:    
  ports:
  - port: 80
    targetPort: 80
  selector: 
    app: app-label
  type: LoadBalancer

但是,当我希望pod在这样的多个端口上侦听时,它不起作用:

apiVersion: v1
kind: Service
metadata: 
  name: service-name
spec:    
  ports:
  - port: 80
    targetPort: 80
  - port: 443
    targetPort: 443
  - port: 6001
    targetPort: 6001
  selector: 
    app: app-label
  type: LoadBalancer
