xtool currently uses AppImage to build its Linux CLI. It is possible to build and run the AppImage on a native Linux host, as well as through Docker (natively or through Docker Desktop on macOS).
Make sure usbmuxd is installed on your host machine. On macOS, usbmuxd is preinstalled.
You can build and run a container with standard Docker Compose commands, for example:
docker compose run --rm xtool
This will spawn a shell inside the container. The xtool root directory will be bind-mounted at /xtool.
To actually access iOS devices from inside Docker, you'll also need to forward the host's usbmuxd to a port which the Docker container's libusbmuxd will connect to. Keep this command running on your host machine:
socat -dd TCP-LISTEN:27015,range=127.0.0.1/32,reuseaddr,fork UNIX-CLIENT:/var/run/usbmuxd
Simply run ./build.sh in this directory. This will output an AppImage to packages/xtool.AppImage, which can directly be invoked.
