Build with Docker

This repository contains an example Go application, used in the Build with Docker guide.

This goal of this guide is to illustrate Docker Build features and best practices.

In this repository

You'll find the Go source code for the application in the cmd directory. For the purpose of the Build guide, there's no need to understand or interact with the source code in any way. The guide only refers to Dockerfile changes.

The Dockerfile in the root directory of this project is the starting point for this guide. It contains the unmodified version.

The chapters directory contains the finished Dockerfile examples for each section of the guide. The sections are enumerated 1-8, and the Dockerfiles in this directory are named after the section that they correspond to.

Tasks

This repository implements Task to make it easier to switch between stages, or reset Dockerfile.

To reset your Dockerfile to a specific stage, install Task and run task goto:<stage>. This overwrites the contents of the Dockerfile to the finished version of the selected stage.

For example, running task goto:1 resets the Dockerfile the starting point of the guide. Running task goto:4 resets the Dockerfile to reflect the finished version of the 4th section of the guide.
