arm architecture support example

[Aiken Qi]

Steps
1. install Snappy Ubuntu Core on RPi 2
https://developer.ubuntu.com/en/snappy/start/raspberry-pi-2/
2. Install Docker app within your Snappy OS on RPi2
3. Import docker image from docker hub, I was using this
https://hub.docker.com/r/ioft/armhf-ubuntu/
4. Run Ubuntu Core as container, and you will have the arm ubuntu for
snappy development.
