Conventions used

There are a number of text conventions used throughout this book.

Code in text: 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 first is called ansible-core, and this contains the Ansible runtime code (such as the ansible-playbook command, which we'll see in use later), as well as some built-in functionality that is core to all playbooks and roles.”

A block of code is set as follows:

  tasks:
  - name: Install/Update to the latest of Apache Web Server
    ansible.builtin.apt:
      name: apache2
      state: latest

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

  handlers:
  - name: Restart the Apache Web Server
    ansible.builtin.service:
      name: apache2
      state: restarted

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

$ python3 --version
Python 3.10.6

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
