cross-docker

This is a wrapper script to let you run different architecture containers with qemu-user

Prerequisites

You must be running in an environment with a working binfmt_misc setup. On Debian, if you install the qemu-user-static package that should be sufficient. On other systems make sure that the binfmt_misc pseudo filesystem is mounted (and configured).

How to use it

./cross-docker run -it armv7/armhf-ubuntu uname -a
Linux a6722bd5dabb 4.1.12 #1 SMP Mon Jan 4 11:26:42 UTC 2016 armv7l armv7l armv7l GNU/Linux

The first time you use it it will download the qemu binaries.

I am too lazy even to do that

If your docker container already has the qemu binary in, you do not need this, eg docker run resin/armv7hf-debian uname -a or docker run justincormack/ppc64le-debian uname -a.

Architectures

If your binfmt_misc is set up right the following architectures should be supported:

aarch64
alpha
arm
armeb
cris
i386
m68k
microblaze
microblazeel
mips
mips64
mips64el
mipsel
mipsn32
