What I would really like is something like Docker to build images for my raspberry pis. Just a single file, shell commands, that's it. I feel that Yocto is already too complicated if you want a reproducable setup for you raspberry pi at home.

I've been working on something recently that you might find interesting: https://github.com/makrocosm/makrocosm

It's not a shell script, but it has makefile rules that make it relatively simple to build a Docker image for your architecture, export it and turn into a filesystem image, build a kernel, u-boot, etc The referenced "example project" repo builds a basic Alpine image for the Raspberry Pi (https://github.com/makrocosm/example-project/tree/main/platf...) and others

It was motivated by frustrations with Yocto at a new job after 8 or so years working on firmware for network equipment using an offshoot of uClinux. Hoping to convince new job to use Makrocosm before we settle on Yocto.

Maybe https://github.com/RPi-Distro/pi-gen works for you.

That’s what Balena does. Base immutable OS and docker images.
