A from-scratch container (podman/docker) image that prints "Hello world!" in a few kilobytes.
The trick is to use Zig to build a static hello world application that is around 4 KB on x86_64. Look here for details.
Yeah, that's it, that's the project - minimal (in size) container hello world image.
Here is how the image compares to the standard hello world:
$ podman image ls
