It’s great to have Docker on Raspberry Pi, and there’s a blog about it.
But one thing I found is that Raspberry Pi is based on ARM CPU, thus do not support x86/x64 instructions. Any Docker image build for x86/x64 won’t work. And, I didn’t find any official Docker image built for Raspberry Pi. resin/rpi-raspbian is widely used and also used by Docker project is a good candidate and is lightweitht, but I still want to use an official one. So, I decided to build one myself.
