Centos7下卸载docker

首先查看Docker版本
# yum list installed | grep docker
docker-ce.x86_64  18.05.0.ce-3.el7.centos @docker-ce-edge
 
执行卸载
# yum -y remove docker-ce.x86_64
 
删除存储目录
 
# rm -rf /etc/docker
# rm -rf /run/docker
# rm -rf /var/lib/dockershim
# rm -rf /var/lib/docker

如果发现删除不掉，需要先 umount，如
# umount /var/lib/docker/devicemapper
