This project provides a script for building customized https://alpinelinux.org/[Alpine Linux] rootfs (a base image if you like) for containers.
It’s quite simple (250 LoC of shell), fast and requires minimum dependencies (just common Linux tools).

TIP: Do you want to just quickly chroot into Alpine Linux, e.g. on CI?
