使用nginx-ingress-controller镜像：quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1

apiVersion:extensions/v1beta1
kind:Ingress
metadata:
name:test-ingress
namespace:default
annotations:
nginx.ingress.kubernetes.io/affinity:cookie
spec:
rules:
-host:test.paas.dc.servyou-it.com
http:
paths:
-path:/
backend:
serviceName:test-deployment
servicePort:8888

其中主要需要配置的是annotations，nginx.ingress.kubernetes.io/affinity: cookie

测试结果：

结果显示，配置会话保持的请求一直请求至同一pods服务，未配置会话保持的请求会使用轮询的方式至后端pods服务
