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?

== Requirements

* Linux system
* http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html[POSIX-sh] compatible shell (e.g. Busybox ash, dash, ZSH, bash, …)
* common userland with `chroot`, `getopt`, `grep`, `sed`, `sha256sum`, `wget` (e.g. from Busybox, GNU coreutils, …)
* `tar` (full-blown)


== Usage

Read documentation in link:{script-name}[{script-name}].
See link:.travis.yml[.travis.yml] for Travis example.

You can copy link:{script-name}[{script-name}] into your repository or download it on demand, e.g.:

[source, sh, subs="+attributes"]
wget https://raw.githubusercontent.com/{gh-name}/v{version}/{script-name} \
    && echo '{script-sha1}  {script-name}' | sha1sum -c \
