Issues getting i386 versions of libraries about docker-brew-ubuntu-core

[tianon]

It looks like they removed the i386-by-default, which is a good thing IMO.

To add the i386 arch, do "dpkg --add-architecture i386" before your
"apt-get update" and you should be good to go:

RUN dpkg --add-architecture i386 && apt-get update && apt-get install -y
libxm4:i386

mkostrikin@MAPC:~$ docker run -it --rm phusion/baseimage /sbin/my_init -- bash

root@661228e1b888:/# apt-get install libxm4:i386
E: Unable to locate package libxm4
root@661228e1b888:/# dpkg --add-architecture i386
root@661228e1b888:/# apt-get update
root@661228e1b888:/# apt-get install libxm4:i386
The following extra packages will be installed: libxm4:i386

Resolved!

This is definitely not the repo for phusion/baseimage. ;)
