Miniconda armv7 crossbuild

Image used to build linux-armv7 conda packages on x64 hardware. It doesn't need to install qemu on the host, nor to have a kernel which support binfmt_misc.

This image integrate a modified version of qemu. For more informations on how to mimic the kernel support of binfmt_misc, look at this post or this one. The image is inspired by resin/armv7hf-debian-qemu.

The image provide minimal setup to build all conda recipies :

• curl & wget & ca-certificates
• git & subversion & mercurial
• conda
• conda-build

Run it on x86_64 hardware

Every commands are started throw qemu, so you have nothing to do :

docker run -it --rm show0k/miniconda-armv7 /bin/bash

Run it on ARM hardware

You have to override the entrypoint of qemu

docker run -it --rm --entrypoint=/bin/bash show0k/miniconda-armv7

Continuous integration support

It works on Travis Ci and CircleCi ! Look at .travis.yml or circle.yml to have basic ci examples.

Docker build based on this image

Wrap your build steps to taint the environment with qemu allowing building on x86_64.
