Guide: ARMv6 (RPi Zero) bootstrap Jessie or Stretch

[alexellis]

To install Docker on ARMv6/PiZero you must follow the tune-up guide #16. Add 1-2GB of swap memory.

Option A: Jessie
Flash Jessie Lite then run:

$ curl -sSL get.docker.com | sh

Option B: Stretch
If you're on stretch then things are more complicated.

Try editing this file and inserting "jessie" instead: /etc/apt/sources.list.d/docker.list

Now you can clone docker/docker and start testing one of the issues listed in this repo under the label: community-supports-docker.

Check your Docker version:

pi@stretch-zero-1:~ $ cat /etc/os-release

Before building you will need to apply this patch to the Dockerfile.armhf file:
