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: "This type of service includes load, which adds a program to memory and prepares for its execution before passing control to the program itself, or execute, which runs an executable file in the context of a pre-existing process."

A block of code is set as follows:

<meta name="go-import" content="package-name vcs repository-url">

Any command-line input or output is written as follows:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In the meantime, systems started to get distributed, and applications started to get shipped in containers, orchestrated by other system software, such as Kubernetes."
