Using Docker's save/load commands to share and run images without using a registry

main.sh

REGISTRY=registry.yourdomain.com

# You may want/need to pull the latest images on a machine which has access to the registry
docker pull $REGISTRY/foo
docker pull $REGISTRY/bar

# You can save the images as tarballs and distribute them as you please
docker save --output=/home/user/images/foo.tar $REGISTRY/foo
docker save --output=/home/user/images/bar.tar $REGISTRY/bar

# And now you can load and these images from the local tarballs without needing to touch the registry
docker load --input=/home/user/images/foo.tar
docker load --input=/home/user/images/bar.tar

docker run $REGISTRY/foo echo Hello, world!
