Copy Images

Images can be copied from drives or portable drives and loaded back into the local Docker repository.

Save an image

docker save -o <save image to path> <image name>

or

docker save <image name> > <save image to path>

For e.g.

docker save -o base-image-openjdk9.tar neomatrix369/openjdk9-base-image:latest

or

docker save neomatrix369/openjdk9-base-image:latest >  openjdk9-base-image.tar

or

docker save neomatrix369/openjdk9-base-image:latest | gzip > openjdk9-base-image.tar.gz

And openjdk9-base-image.tar or openjdk9-base-image.tar.gz are created in the folder where the command is executed.

Load an image

docker load -i <path to image tar file>

or

docker load < <path to image tar file>

For e.g.

docker load -i openjdk9-base-image.tar

or

docker load < openjdk9-base-image.tar

or

docker load < gzip < openjdk9-base-image.tar.gz
