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: "When ansible or ansible-playbook is directed at an executable file for an inventory source, Ansible will execute that script with a single argument, --list."

A block of code is set as follows:

- name: add new node into runtime inventory
  add_host:
    name: newmastery.example.name
    groups: web
    ansible_ssh_host: 192.168.10.30

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 first is an SSH feature, ControlPersist, which provides a mechanism to create persistent sockets when first connecting to a remote host that can be reused in subsequent connections to bypass some of the handshaking required when creating a connection."
