docker

first, build docker image

./build_docker_image.sh

last, using docker compose, to startup a container

./compose_docker_image.sh

change volumes to your own

How to use

1. add "old.img" and "new.img" to "./extern-volume/input/"(mounted)
2. add "playload_private_key.pem" and "playload_public_key.pem" to "./extern-volume/input/"(mounted)
3. run docker
4. new delta package is "./extern-volume/output/build.tar.gz.xz"
