# cat ubuntu-14.04-x86_64-minimal.tar.gz |docker import-ubuntu:14.04

Then view the newly imported mirrors

# Docker Images

sending image list
Pu Shing Repository Ouruser/sinatra (3 tags)

Save and load mirror like To save a mirror

If you want to export mirrors to local files, you can use the Docker Save command

# sudo docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE

   ... # sudo docker save-o Ubuntu_14.04.tar ubuntu:14.04

Load Mirror like

You can use Docker load to import from the exported local file to the local mirror library, for example

# sudo docker load--input ubuntu_14.04.tar
or
# sudo docker load < Ubuntu_14.04.tar

This will import the mirror and its associated metadata information (including tags, etc.) to remove the local mirror
