通过maven推送镜像到SWR仓库-故障处理一例

1. 说明

• 基础配置参考maven(0.4)那篇即可，此处不再赘述；

• 此篇为排错篇，被华为云SWR仓库坑惨了；

• 此篇只对比各个不同的maven-docker-plugin版本，在使用中的区别；

2.排错过程

2.1.起因

客户的代码环境均是在本地，包括gitlib仓库也是部署在本地；

客户希望通过本地IDE环境，在线下实现代码开发，并通过Maven的maven-docker-plugin插件，实现本地容器镜像封装，同时推送容器镜像到华为云SWR镜像仓库，尽可能的实现发布流程自动化；

但是在实现的时候，往华为云上推送镜像时，一直出错，无法成功推送；

插件推送时，报错信息如下：

2.2.先说结论

整了快一天了，死活是调试不通，一直以为是自己的配置文件有问题，各种查文档，各种改配置，都快崩溃了；

快下班的时候，突然想着，要不往hub.docker.com上推送一下试试看，没马想竟然一下子就推送成功了，我cao；

实在没想到是华为云SWR平台有问题啊。。。

找到问题所在就好办了，换到华东-上海一地域，也是一下子就推送成功了，了然。

上表是各种测试后的结果；

因为日常默认使用的地域就是（华东-上海二），所以就被抗了一天时间；

没想到会是SWR平台的问题，是因为前几天使用0.4.13版本的插件，是能成功的。

3.总结

个人猜测，大概是因为（华东-上海二）目前已经不开放给新用户使用了，所以该地域的很多服务，已经不怎么更新了；

所以这就算是个BUG了吧。
