This project provides script for making customized https://alpinelinux.org/[Alpine Linux] disk images for virtual machines.
It’s quite simple (250 LoC of shell), fast (~40 seconds on Travis CI including Travis VM initialization) and requires minimum dependencies (QEMU and filesystem tools).

TIP: Don’t need VM, just wants to chroot into Alpine Linux (e.g. on CI)?
     Try https://github.com/alpinelinux/alpine-chroot-install[alpine-chroot-install]!


== Requirements

* Linux system with common userland (Busybox or GNU coreutils)
* POSIX-sh compatible shell (e.g. Busybox ash, dash, Bash, ZSH)
* qemu-img and qemu-nbd (automatically installed by the script if running on Alpine)
* e2fsprogs (for ext4), btrfs-progs (for Btrfs), or xfsprogs (for XFS) (automatically installed by the script if running on Alpine)
