Multi-Arch image

Am interested in seeing how we can standardize the images here a bit and consolidate maintenance effort. In particular am curious how we can make a multi-arch image. There's [a good blogpost]( https://blog.docker.com/2017/11/multi-arch-all-the-things/ ) on this topic. It would be good to determine what the current issues prompting the different images we have are and how we address those issues in a general way that benefits all of the images here.
