操作步骤

下文以nginx镜像创建无状态工作负载，并创建一个具有pass-through的Service。

使用nginx镜像创建无状态负载。

apiVersion: apps/v1     
kind: Deployment         
metadata:
  name: nginx            
spec:
  replicas: 2                     
  selector:              
    matchLabels:
      app: nginx
  template:              
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx:latest
        name: container-0
        resources:
          limits:
            cpu: 100m
            memory: 200Mi
          requests:
            cpu: 100m
            memory: 200Mi
      imagePullSecrets:
      - name: default-secret

Loadbalance类型的Service，并设置kubernetes.io/elb.pass-through为true。本示例中自动创建了一个名为james的共享型ELB实例。

Loadbalance类型的Service具体创建方法请参见自动创建负载均衡类型Service。

apiVersion: v1 
kind: Service 
metadata: 
  annotations:   
    kubernetes.io/elb.pass-through: "true"
    kubernetes.io/elb.class: union
    kubernetes.io/elb.autocreate: '{"type":"public","bandwidth_name":"cce-bandwidth","bandwidth_chargemode":"bandwidth","bandwidth_size":5,"bandwidth_sharetype":"PER","eip_type":"5_bgp","name":"james"}'
  labels: 
    app: nginx 
  name: nginx 
spec: 
  externalTrafficPolicy: Local
  ports: 
  - name: service0 
    port: 80
    protocol: TCP 
    targetPort: 80
  selector: 
    app: nginx 
  type: LoadBalancer
