Overview
Takes an image name or ID and saves its content (as individual layers) into a TAR archive format. By default it dumps the content to stdout, so it must be redirected to a file.
docker save [options] <image-id>
docker save 6902f4d604b9 > postgresql-95-rhel7.tar
The flattened view of the image's filesystem can be obtained with:
mkdir flat cd flat for i in $(cat ../manifest.json | sed -e 's/^.*Layers\":\[//' -e 's/\]}\]//' -e 's/"//g' -e 's/,/ /g'); do tar xfv ../$i; done
