Recently I worked on a project where a large refactor had taken place but I wanted to ensure that there was no changes to the built output of the docker container. So while the diff in Github was quite large with many files moved around the output should remain almost identical aside from a few extra files removed.

Have you seen this error?
building the system configuration...
error: flake 'git+file:///Users/matt/nixfiles' does not provide attribute 'packages.aarch64-darwin.darwinConfigurations.Bebop.system', 'legacyPackages.aarch64-darwin.darwinConfigurations.Bebop.system' or 'darwinConfigurations.Bebop.system'

Background: I had some projects from school that I wanted to revisit and compile again, specifically a game called Worm.

How I cross compiled Go to run on the Winkhub and installed a custom web app to control the lights locally.
TL;DR; Be sure to compile with Go 1.5 with the following settings:
GOOS=linux GOARCH=arm GOARM=5 go build .
This post picks up where part 1 left off. Here is some of the troubleshooting I had to go through since following the instructions did not go smoothly for me.
How I liberated my Winkhub from the Cloud

This post covers how to setup CoreOS with iptables on DigitalOcean. It also covers how to start a Docker container using systemd to keep the container running after crashes and reboots.
