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...
