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: "The sudo command is a well known, but is often used in its more dangerous form."

A block of code is set as follows:

- hosts: all 
  remote_user: vagrant
  tasks: 
    - name: Ensure the HTTPd package is installed 
      yum: 
        name: httpd 
        state: present 
      become: True 

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

- hosts: all 
  remote_user: vagrant
  tasks: 
    - name: Ensure the HTTPd package is installed 
      yum: 
        name: httpd 
        state: present 
      become: True

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