Go Cookbook

Overview of this book

Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library. This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers. The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.

Using containerization with Docker

Docker is a container technology for packaging and shipping applications. Other advantages include portability, a container will run the same way regardless of the host OS. It provides a lot of the advantages of a virtual machine, in a more light-weight container. It's possible to limit resources consumption of individual containers and sandbox your environment. It can be extremely useful for having 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.
