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

# Task

The `/proc/mounts` is a virtual file that displays the currently mounted filesystems in a Linux system. We want to access the file and display its contents on the screen.

# Explanation




In this exercise, you are provided with code to read the content of the text file named `mounts` in the `/proc/` directory using Ansible. First, let’s take a look at an overview of the code:

- **Line 2**: We write the play named “Exercise” with the host `all` for the target hosts of execution.

- **Lines 4–5**: We create a variable named `myfile`, which contains the path of the `mounts` file.

- **Lines 7–8**: We add a task named `Set file_content` and use the `ansible.builtin.set_fact` Ansible module to create a custom Ansible fact.

- **Line 9**: We specify the path for the `mounts` file as a source using the `myfile` variable in the Ansible `lookup` plugin. A `lookup` plugin defines the `file` type and the variable name `myfile`.

- **Lines 11–12**: We add a task named `Display the current mounts` and use the `ansible.builtin.debug` Ansible module to display the value of the variable on the screen.

- In the `inventory` file, we set the host for our target host `localhost`.

Now, there is a problem with the provided code. It has some errors. To complete the task, fix the errors in the playbook so that it displays the contents of `mounts` file successfully. After fixing the errors in the playbook, execute the `read_file.yml` playbook.

If your playbook is executed successfully, you can see the contents of the `mounts` file on the screen by using the command `cat /proc/mounts`.
