Comportement

Remplacer ou fusionner des dictionnaires (avec "hash_behaviour=replace" dans ansible.cfg) :

# Remplacer             # Fusionner
---                     ---
  vars:                  vars:
    dict:                merge:
      a: "valeur"           dict: 
      b: "valeur"             a: "valeur" 
                               b: "valeur"

# Comment fonctionne la fusion ?
Vos vars [host_vars]  -->  vars par défaut [rôle actuel] --> vars par défaut [rôle inclus]
  
  dict:          dict:              dict:
    a: "1" -->     a: "1"    -->      a: "1"
                   b: "2"    -->      b: "2"
                                      c: "3"
