In an era of IT environments, automation is no longer a luxury—it's a necessity. Ansible, an open-source IT automation tool, has become a go-to solution for streamlining IT tasks. This comprehensive course aims to equip you with both fundamental and advanced Ansible knowledge.

You'll start by installing Ansible, understanding its architecture, and diving into inventory management and playbook creation. Next, you'll explore variables, conditional statements, loops, handlers, roles, and collections. After that, the course dives into Ansible for Linux-specific tasks and troubleshooting techniques to resolve common problems like connection failures, missing parameters, and syntax errors. 

After completing this course, you'll have gained a robust understanding of Ansible, with the ability to create efficient playbooks, manage inventory, troubleshoot common problems, and automate a wide range of IT tasks. These skills will provide a strong foundation for a thriving career in IT infrastructure management.

Automating IT Infrastructure with Ansible

We often need to print messages or the variable's value in Ansible. The statements can be text, Ansible variables, facts, and so on.

## Ansible `debug` module



The Ansible `ansible.builtin.debug` module is a useful tool for displaying information during playbook execution. It allows us to print specific variables or custom messages to the standard output, providing insights into the state of the system or playbook execution. The `debug` module is commonly used for debugging purposes, troubleshooting, or simply to gain more visibility into the Ansible playbook's operations.


It can also be used to display messages, expressions, and variables in different formats, such as JSON, YAML, or plaintext. The output can be saved to a file or displayed in the console.



## Parameters of the `debug` module

The Ansible `debug` module has three parameters:

- The `msg` parameter

- The `var` parameter

- The `verbosity` parameter

> **Note:** If we use the `debug` module without specifying any parameters, the default message `"Hello world!"` is printed.

## The `msg` parameter

The `msg` parameter is used to print a customized message. We can also combine text and variables in the `msg` field. We use the double curly braces to access the value of a variable inside the message. For example, `{{ ansible_version }}` will print the actual value of the `ansible_version` variable.

## The `var` parameter

The `var` parameter is used to display the value of a specific variable. When we use the `var` parameter, we need to specify the name of the variable we want to display, like `var: my_variable`.

## The `verbosity` parameter

The `verbosity` parameter is used to control the level of details in the output when using the `msg` parameter.
It accepts values from 0 to 4. When the `verbosity` parameter is specified, the text is displayed on the screen only when the code is executed with the same verbosity level or a higher one. Otherwise, we obtain a `skipping` state on the task.

## The verbosity levels

There are five verbosity levels in Ansible. We can specify the running verbosity level using the `-v` parameter of the `ansible-playbook` command, as shown in the following table:
