To get the most out of this book

I suggest you get some familiarity with Go by implementing a few applications, such as simple web services. Familiarity with a Docker tool would be a plus because we will be using it for running some of the tools that our microservices will be using. Finally, I strongly suggest implementing, running, and playing with the example microservices that we will be implementing so that all your knowledge will be cemented by practice.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
