Installing Docker on Raspbian

Raspbian is merely just a distribution of Debian Stretch, so you can use the Debian Stretch sources.
The important information is that the Raspberry Pi is a armhf architecture hardware, not arm64.
uname -a

Linux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l GNU/Linux

All Raspberry Pis are compatible with arm32v6.
armv7l is a 32-bit processor.

file /bin/bash
/bin/bash: ELF 32-bit LSB executable, ARM

You may see Docker images at the Docker hub built for arm32v7 or arm32v6.
64-bit arm processors are armv8l or higher.
