Docker Managing images Saving and loading Docker images
Example
docker save -o ubuntu.latest.tar ubuntu:latest
This command will save the ubuntu:latest image as a tarball archive in the current directory with the name ubuntu.latest.tar. This tarball archive can then be moved to another host, for example using rsync, or archived in storage.
Once the tarball has been moved, the following command will create an image from the file:
docker load -i /tmp/ubuntu.latest.tar
Now it is possible to create containers from the ubuntu:latest image as usual.
