Want to develop, build, test, and deploy consistent code across multiple platforms and even architectures? Maybe work on your Raspberry Pi or ODROID code from your laptop, push a Docker image, then pull the exact same code onto your target hardware device? Maybe even automate all these steps using Continious Integration?! Yeah why not! :)
Background I first tried this on Circle CI but ran into some hiccups with with binfmt_misc not being quite full acessible on their build machines.
