dockerfile - docker build images失败后如何删除

Question

最近刚入门docker，打算跟着官方例子学习，随手找了个redis的example,结果在build途中，容量达到了15g+，中途想放弃直接关闭shell了。 后来怎么找都没法找到images，自然占着的空间也没法清理了，请问有什么办法清理呢。 包括docker images也用了，也找不到容器。
是在这一句后中断的,docker build -t /redis .

docker images

The names, IDs and other parameters of all images in the system will be displayed, as follows:

Generally, the image building failsREPOSITORY，TAG显示<none>, but the ID is still there. Find your failed id

docker rmi -f [your failed image id]

That’s it.
