Spring Cloud Config Server迁移节点或容器化带来的问题
作者:CQITer小编 时间:2018-05-20 01:39
如果您跟我一样,目前正在使用Spring Cloud Config做为配置中心的话,本篇将来要描述的问题,强烈推荐了解和关注!因为这个问题目前存在于所有的版本中,还没有完全修复。

问题现象
为了说明下面的内容,我们可以先尝试重现一下问题:在一个测试环境中,将Spring Cloud Config的配置中心迁移到另外一个节点上,即配置中心的IP地址发生了变化。在完成迁移之后,我们会发现该环境下各个微服务应用的健康状态会变得时好时坏,并且在日志中会出现类似下面的报错:
