If anyone wants to try Docker 1.13 on Hikey, I've done a quick and dirty port of the 64-bit version of HypriotOS.
The emmc image is here: http://people.linaro.org/~bill.fletcher/HypriotOS_Hikey/
The docker daemon should start at boot time. I've tested HDMI, USB and USB ethernet. No idea about wifi or bluetooth. There are some complaints about bluetooth when it boots.
