今天手欠，把docker的repository地址修改了一下，然后在查看docker version的时候就出现一下问问题，折腾了我一个小时才最终解决问题。
分享一下过程，大家避免踩坑
问题：

瞬间泪崩
思考了一下
首先想到就思路就是是不是修改了daemon.json 了repository地址导致的。
执行如下代码，验证自己的思路
docker debug
看到下图提示：
确定了的确是 repository地址错误的问题了
问题解决：
首先删除/etc/yum.repos.d/docker-ce.repo 里面错误的 repository 的地址 操作如下：
cd /etc/yum.repos.d
Vim docker-ce.repo
发现了，多了一个错误的地址
果断 删除
rm -tf e4fquiqb.mirror.aliyuncs.com.re
第2步：修改 daemon.json 的配置
vim /etc/docker/daemon.json
再重新reload一下
systemctl daemon-reload
重新启动一下docker
systemctl restart docker
问题解决：
