A system administrator's guide to getting started with Ansible

Based on this tutorial with some small adaptations for RHEL 8.

TL;DR:

1. Install Ansible on your control node;
2. Add the private IP of the managed nodes to the /etc/hosts file and name them as "vm2", "vm3" and so on. E.g. 192.168.1.100 vm2;
3. Make sure the ssh is working fine between the control node and the managed nodes;
4. Use the "hosts" file from this repository as your ansible inventory;
5. Run the playbook myplaybook.yml 😎👍
