删除none镜像时，报错，提示Error response from daemon: conflict: unable to delete 6ec9a5a0fc9f (cannot be forced) - image has dependent child images

• 查询指定镜像依赖的子镜像

#since更后是要查询的镜像ID，即想要删除的镜像ID
docker image inspect --format='{{.RepoTags}} {{.Id}} {{.Parent}}' $(docker image ls -q --filter since=63973a2bef47)

• 查询出来后，删除掉对应的依赖的镜像，此时关联的none镜像也会被删除
  docker rmi xxx
