This project enables building a Docker image to allow running 64-bits ARM Debian builds on non-arm hosts (like Travis build agents).
Before building images from this image or running containers from those on x86
architecture execute the following command:
docker run --rm --privileged multiarch/qemu-user-static:register --reset
As described in its GitHub project this will register the static QEMU binary that exists in this base image for all supported processors.
