使用以下方法：

[root@iZm5eeq7orgtvuxpgma2f4Z ~]# systemctl stop docker
[root@iZm5eeq7orgtvuxpgma2f4Z docker]# rm -rf /var/lib/docker
[root@iZm5eeq7orgtvuxpgma2f4Z docker]# systemctl start docker
[root@iZm5eeq7orgtvuxpgma2f4Z docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

/var/lib/docker 是docker默认工作路径
