An example of Docker multi-stage building with Golang

Introduction

This repository is part of my blog post on Docker multistage builds.

Howto Docker multistage builds

To illustrate this purpose, I use a small golang app that write ascii colored output. It use a lib + a local package call myframe.go.

In the Dockerfile, first stage build the golang app binary, while second stage copy it into the final image for run purpose.

Bonus

As we produce a binary, I can make the second stage using the magic FROM scratch that allowed me to make a 2Mb tiny Docker image!
