Overview of this book

Go is the language of the Internet age, and the latest version of Go comes with major architectural changes. Implementation of the language, runtime, and libraries has changed significantly. The compiler and runtime are now written entirely in Go. The garbage collector is now concurrent and provides dramatically lower pause times by running in parallel with other Go routines when possible. This book will show you how to leverage all the latest features and much more. This book shows you how to build powerful systems and drops you into real-world situations. You will learn to develop high quality command-line tools that utilize the powerful shell capabilities and perform well using Go's in-built concurrency mechanisms. Scale, performance, and high availability lie at the heart of our projects, and the lessons learned throughout this book will arm you with everything you need to build world-class solutions. You will get a feel for app deployment using Docker and Google App Engine. Each project could form the basis of a start-up, which means they are directly applicable to modern software markets.

Chapter 11. Deploying Go Applications Using Docker

Docker is an open source ecosystem (technology and range of associated services) that allows you to package applications into containers that are simple, lightweight, and portable; they will run in the same way regardless of which environment they run on. This is useful when you consider that our development environment (perhaps a Mac) is different from a production environment (such as a Linux server or even a cloud service) and that there is a large number of different places that we might want to deploy the same application.

Most cloud platforms already support Docker, which makes it a great option to deploy our apps into the wild.

In Chapter 9, Building a Q&A Application for Google App Engine, we built an application for Google App Engine. We would need to make significant changes to our code if we decided that we wanted to run our application on a different platform even if we forget about our use of Google Cloud Datastore. Building...
