Save and load the Docker image

Save the mirror

If you want to export a mirror to a local file, you docker save command.

$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
ubuntu              14.04               c4ff7513909d        5 weeks ago         225.4 MB

$sudo docker save -o ubuntu_14.04.tar ubuntu:14.04

Load the mirror

You docker load to import from an exported local file to a local mirror library, for example

$ sudo docker load --input ubuntu_14.04.tar

Or

$ sudo docker load < ubuntu_14.04.tar

This imports the mirror and its associated metadata information, including labels, and so on.
