docker image has dependent child images 错误

这样的错误，原因是有另外的 image FROM 了这个 image，
可以使用下面的命令列出所有在指定 image 之后创建的 image 的父 image

docker image inspect --format='{{.RepoTags}} {{.Id}} {{.Parent}}' $(docker image ls -q --filter since=d13c942271d6)

下面是操作过程

?  ~ docker rmi d1 #删除失败
Error response from daemon: conflict: unable to delete d13c942271d6 (cannot be forced) - image has dependent child images
?  ~ docker images -a #查看所有镜像
