Der Computer muss vorbereitet werden. Im CI erfolgt dies mithilfe von molecule/default/prepare.yml:

---
- name: prepare
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: buluma.bootstrap
    - role: buluma.epel

Siehe auch eine vollständige Erklärung und Beispiel zur Verwendung dieser Rollen.
