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:
1
|
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
