Docker 把硬盘占满了.

Question

$> /var/lib/docker/devicemapper/devicemapper

这个文件已经6个 G 了. 请问有什么办法清空一下吗?

硬盘本来就不大.

Answer 1

I found that it’s just a matter of putting the container content and pointers on another disk.

Answer 2

Theoretically, the one that takes up the most space should be aufs.

You can delete the image through docker rmi
And docker rm deletes the container to clean it up.

Answer 3

Use -v to map volumes when starting up. Don’t forget to delete -v when deleting the container
