Go Programming Cookbook - Second Edition

By: Aaron Torres

Overview of this book

Go (or Golang) is a statically typed programming language developed at Google. Known for its vast standard library, it also provides features such as garbage collection, type safety, dynamic-typing capabilities, and additional built-in types. This book will serve as a reference while implementing Go features to build your own applications. This Go cookbook helps you put into practice the advanced concepts and libraries that Golang offers. The recipes in the book follow best practices such as documentation, testing, and vendoring with Go modules, as well as performing clean abstractions using interfaces. You'll learn how code works and the common pitfalls to watch out for. The book covers basic type and error handling, and then moves on to explore applications, such as websites, command-line tools, and filesystems, that interact with users. You'll even get to grips with parallelism, distributed systems, and performance tuning. By the end of the book, you'll be able to use open source code and concepts in Go programming to build enterprise-class applications without any hassle.

Using containerization with Docker

Docker is a container technology for packaging and shipping applications. Other advantages include portability, since a container will run the same way regardless of the host OS. It provides a lot of the advantages of a virtual machine, but in a more lightweight container. It's possible to limit the resource consumption of individual containers and sandbox your environment. It can be extremely useful to have a common environment for your applications locally and when you ship your code to production. Docker is written in Go and is open source, so it's simple to take advantage of the client and libraries. This recipe will set up a Docker container for a basic Go application, store some version information about the container, and demonstrate hitting a handler from a Docker endpoint.
