Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The other change that we have made to the servers.yaml file is we have added entries to the /etc/hosts directory."

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

command: -server --client 0.0.0.0 --advertise <%= @consul_advertise %> -bootstrap-expect <%= @consul_bootstrap_expect %>

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The next thing we need to do is click on the Create button."
