Steps to create a docker based RPi3 image

docker-rpi3-image-setup

# Download latest image from http://blog.hypriot.com/downloads/. Assuming v0.8.0.
unzip hypriotos-rpi-v0.8.0.img.zip

# And identify SSD disk
diskutil list 

# Unmount disk. Assuming we identified /dev/disk2 in previous step
diskutil unmountdisk /dev/disk2

# Flash SD card. May take up to 5min with no feedback
sudo dd if=hypriotos-rpi-v0.8.0.img of=/dev/rdisk2 bs=1m

# Unmount again
diskutil unmountdisk /dev/disk2
