 Hey, I am a Raspberry PI (and a GraalVM) enthusiast!

+This a sample project to demonstrate how to build a Spring Boot / GraalVM Docker image for `arm64` architecture.
 It produces a `linux/arm64` ready docker image, and can be run on a Raspberry Pi for example. In my case, it even runs on a `Raspberry Pi Zero 2 W`, which is insane.
 
-GraalVM needs at least `512 MB` to run, what is not possible on the `Raspberry Pi Zero 2 W`. So I had to produce a `linux/arm64` image from a `linux/amd64` host.

 - Install QEMU : `docker run --privileged --rm tonistiigi/binfmt --install all` / `docker run --rm --privileged multiarch/qemu-user-static --reset -p yes`.
 - Validate that it works: `docker run --platform=linux/arm64 --rm -t arm64v8/ubuntu uname -m`. It should return `aarch64`.
