This is a solution for the Udemy course "Ansible for Absolute Beinnger - Hands On - DevOps": https://www.udemy.com/course/learn-ansible/
Some best practices were not applied here as this is a test project (as an example the inventories.txt files has the servers' passwords, which is a really bad practice)
3 servers were provisioned as shown during the course using CentOS 8 (in the course CentOS 7 is used, though).
If you want to run the playbook on your ansible controler agains your targets please update the inventories.txt file with the correct IP addresses.
I decided not use use a simple playbook but using Ansible roles as well.
In the future I will use Vagrant to provision the VMs.
