scratch-based dockerization of toybox, the BusyBox-alternative with a BSD-license

As the site says:

Toybox combines many common Linux command line utilities together into a single BSD-licensed executable. It's simple, small, fast, and reasonably standards-compliant (POSIX-2008 and LSB 4.1).

Toybox's main goal is to make Android self-hosting by improving Android's command line utilities so it can build an installable Android Open Source Project image entirely from source under a stock Android system. After a talk at the 2013 Embedded Linux Conference explaining this plan (outline, video), Google merged toybox into AOSP and began shipping toybox in Android Mashmallow.

This image uses an alpine:edge build step as a staging environment, but is built around the binary releases of toybox found at https://landley.net/toybox/bin/

The source code for this image is hosted on GitHub in the backplane/conex repo.

Usage

You can launch the container interactively with a command like:

docker run --rm -it backplane/toybox

A nonroot user is pre-created in the password file, you can access it with Docker's --user argument like this:

docker run --rm -it --user nonroot backplane/toybox

To see what version of toybox is in the container you can run toybox --version, like this:

docker run --rm backplane/toybox toybox --version

Issues

  • At present the lack of stty can make it a little annoying to work in the toybox shell because you might experience issues with backspace/delete.
  • You may also find it unpleasant to operate without shell history.
