To get the most out of this book

To get the most out of this book and experiment with the accompanying code, you need to have a fairly good understanding of programming in Go as well as sufficient experience working with the various tools that comprise the Go ecosystem.

In addition, the book assumes that you have a solid grasp of basic networking theory.

Finally, some of the more technical chapters in the book utilize technologies such as Docker and Kubernetes. While a priori knowledge of these technologies is not strictly required, any prior experience using these (or equivalent) systems will certainly prove beneficial in better understanding the topics discussed in those chapters.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In the following code, you can see the definition of a generic Sword type for our upcoming game."

A block of code is set as follows:

type Sword struct {
  name string // Important tip for RPG players: always name your swords!
}
// Damage returns the damage dealt by this sword.
func (Sword) Damage() int {
  return 2
} 
 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

type Sword struct {
  name string // Important tip for RPG players: always name your swords!
}
// Damage returns the damage dealt by this sword.
func (Sword) Damage() int {
  return 2
} 

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The following excerpt is part of a system that collects and
publishes performance metrics to a key-value store."

Warnings or important notes appear like this.
