    190. #存在一个问题,登陆进去后,页面提示又要登陆,问了开发,登陆那块做了session,k8s默认负载均衡策略是rr,第一次登陆在第一个pod,第二次登陆到第二个pod,session就会丢失.
    192. 解决方案:
    193. 1.kube-proxy默认使用的是iptables,默认是rr轮询.可以切换ipvs负载均衡,使用ip_hash.
    194. 2.yaml文件replicas的值设置成1
    195. 3.使用StatefulSet部署,而不使用Deployments部署.
    196. StatefulSet是为了解决有状态服务的问题（对应Deployments和ReplicaSets是为无状态服务而设计）
