docker强制删除none的image镜像

昨晚使用dockerfile生成一个镜像，中途断网了，导致images的REPOSITORY出现<none>
他的名字和tag都是为none
错误提示：

Failed to remove image (bceaae03d0ea): Error response from daemon: conflict: unable to delete bceaae03d0ea (must be forced) - image is being used by stopped container 31142aabc63c

首先我查看镜像
再查看容器，包括运行后退出的。
#引起上面的原因是docker官方要求，docker rmi image_id 只能删除未被使用的image。
由上面这段话，我推断到有容器在使用这个镜像，所以没法删除。
排除方法：1、删除和bceaae03d0ea镜像有关联的容器 2、再重新删除镜像
