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 **Message of the Day (MOTD)** file displays a welcome message to the users when they connect to the system. It is stored under the `/etc/motd` directory.

## Explanation

In this exercise, create a text file named `motd` in the `/etc/` directory using Ansible. To complete the task, you need to perform the following steps:

1. In the `create_file.yml` file, write the play named "exercise".

2. Now, add a task named "creating a text file" and make the necessary changes in the playbook to create the `motd` file in the `/etc/` directory.

3. The `motd` file should contain the following contents:

   - `Example of`
   - `Message of the Day`

4. Add the additional parameters to set the owner, group, and mode of the file:

   - The `owner` is `root`.
   - The `group` is `root`.
   - The `mode` is `0644`.

5. In the `inventory` file, write the statements for the target `localhost`.

After successfully writing the playbook, execute the `create_file.yml` playbook.


If your playbook is executed successfully, you can see the contents of the `motd` file using the command `cat /etc/motd`.
