If your host is CentOS, and the use of the default
loop file, that no way, CentOS no Union FS implementation, this sparse file to simulate is going to grow. Ubuntu / Debian will not have this problem.
As for the removal of the mirror is not used to build the middle of the mirror problem. You can first
docker images -a look at is not too much
<none> mirror, and some of them are such images. Delete them directly
docker rmi $(docker images -aq -f "dangling=true") . And then look should be much less.
In addition, the contents of your container is also in the storage layer. Can
docker ps -a look at is not a lot of the previous container is not deleted, the same can also
docker rm $(docker ps -aq -f "dangling=true") to delete.
