First Role

So, to start building some custom roles to manage a single EC2 instance, here is an example of tasks you may want to execute initially on a new instance.

mkdir -p roles/initialize/tasks

roles/initialize/tasks/main.yml

---
# Update all packages
- name: Upgrade all packages
  dnf:
    name: "*"
    state: latest

# Reboot server
- name: Reboot server
  reboot:
    reboot_timeout: 180
