A Tiny golang Docker container example for resin.io

A Tiny golang Docker container example for resin.io

This example demonstrates the use of Docker multi-stage builds to make very small runtime containers. In this example deploy a simple hello world webserver that listens on port 80. The resulting docker container is only 5.26 MB, compared to 642 MB of full resin/raspberrypi3-golang:1.8 golang base image that is a massive improvement.
