怎么干净的卸载docker(docker,web开发)

先上服务器环境信息：

卸载的原因：

宿主机过段时间就磁盘100%了，导致continart异常退出，后来找了很多解决方案，才发现是安装docker的时候有个配置文件错误（正常的应该是|storage driver: overlay2）。

上干货：

①卸载

yumremovedocker\docker-client\docker-client-latest\docker-common\docker-latest\docker-latest-logrotate\docker-logrotate\docker-selinux\docker-engine-selinux\docker-enginerm-rf/etc/systemd/system/docker.service.drm-rf/var/lib/dockerrm-rf/var/run/docker

②安装
