springcoud-kubernetes实践之用kubernetes做注册中心（包括负载均衡熔断）_kubernetes替换注册中心

本文是spring-cloud-kubernetes实战，主要内容是在kubernetes上部署两个应用：provider-service和consumer-service，通过spring-cloud-kubernetes提供的注册发现能力，实现consumer-service调用provider-service提供的http服务；

前提条件

请确保你已经在服务器上搭建kubernetes集群

开发provider-service

1.创建maven项目，添加如下pom.xml
