Mirroring Save / Load: docker load/ docker save; exported as an image file, and then use docker load command to import the file into a mirror, the mirror will save all of history. Than docker export command to export the file size, well understood, as it will save all the history of mirroring.

Container import / export: docker import/ docker export; a container export file, and then use docker import command will import container into a new image, but compared docker save command, you will lose all container file metadata and history, saved only when the container the state, the equivalent of a virtual machine snapshots.

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

要删除全部image的话
