apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  labels:
    app: nginx
spec:
  sessionAffinity: ClientIP  #会话保持
  sessionAffinityConfig:
    clientIP:
      timeoutSeconds: 10800  #session保持的时间，这个时间默认是10800秒，也就是三个小时
  ports:
  - port: 8001
    targetPort: 80
  selector:
    app: nginx
