错误呈现

我们在通过gitlab-ci helm方式部署到k8s容器中时，有时可能觉得这个版本不是我想要的，就要中断发布【当然这里虽然中断了，但是代码其实已经部署到k8s 容器中】，这个时候带来的后果就是上图所示，第三步deploy 的时候，不管重试多少次都会有下面的错误，下次再次提交代码的时候，都不能成功发版，。

解决方案
**

进入k8s控制台，使用helm rollback 回滚当前服务到历史版本，然后再次通过gitlab 发布即可

查询服务部署历史版本

helm history 服务名 -n namespace

回滚服务到当前版本到上一个版本

helm rollback 服务名 -n namespace
