[root@guanvps ~]# docker rmi ae5
Error response from daemon: conflict: unable to delete ae513a47849c (must be forced) - image is referenced in multiple repositories
[root@guanvps ~]# docker rmi ae5 --force

[root@guanvps ~]# docker rmi ae5

如上可见依然无法删除,猜测目录文件记录着镜像的信息有残留
进入/var/lib/docker/images/的相关目录

[root@guanvps ~]# cd `find /var/lib/docker -path '*/imagedb/*tent/sha256'`
[root@guanvps sha256]# ls

发现的确残留文件信息,内容是image的inspect信息,删掉文件后查看没有了
