Conventions

In this book, you will find a number of styles of text 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: "You can now log in with the username root and password 5iveL!fe."

A block of code is set as follows:

production: &base
  gitlab:
    port: 80 

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

[core]
      editor = 'vim'

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

$ sudo gitlab-ctl restart

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Postfix will ask you what kind of installation you want; choose the Internet Site option."
