I’ve created docker images for 
arm. It is based on lopsided98’s archlinux-docker project.
You can find it on docker hub here:
https://hub.docker.com/r/sradjoker/eos-arm
To run it on your system, you can use:
docker run --rm -ti sradjoker/eos-arm
Note that this docker container is to be run on x86_64 systems.
Let me know if you have any comments, suggestions, or questions.
Thanks to @them4d for his help!!
P.S.
If you getting exec error when running the image, run this first before running the image:
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
