 *Norme*: En utilisant les variables
 
+### Prérequis
 
-### Préparation
+Avoir à disposition  le playbook
+### Atelier 1 - faciliter l'exploitation et la maintenance d'un playbook
 
-Récupérer la solution de l'atelier *"handlers"*:
+Identifier toutes les modifications à faire au playbook _setup.yml_ si on veut changer le nom du compte à créer.
 
-```bash
-cd
-git clone  -b https://infra.opendoor.fr/git/tom/sib_12_handlers
-cd sib_12_handlers
-```
+Comment simplifier une future modification de cet emplacement ?
 
-### Pratique:
+### Atelier 2 - variables de play
 
-Ce playbook présente beaucoup de redondance (nom de répertoire, nom du site ...) ce qui ne facilite pas sa maintenance.
+Se mettre d'accord sur le nom de variable à utiliser.
 
-J'ai choisie d'utiliser les variables:
+Remplacer toutes les occurences du nom d'utilisateur par la variable
 
-  - apache_documentroot
-  - apache_site_name
+Rajouter une section _vars_ au playbook dans laquelle sera définie notre variable
 
-J'ai défini ces variables dans la section _vars_ du playbook. C'est loin d'être idéal ...
+Voir fichier setup_2.yml
 
-### Performance
+### Atelier 3 - variables d'inventaire
 
-Il est désormais facile d'adapter le playbook pour qu'il traite un autre site que www.orsys.fr
+Comment faire pour que à chaque machine soit associé un compte différent ?
+
+Voir fichier setup_3.yml et host_vars/centos1.formation.opendoor.fr
+
+### Atelier 4 - variables de type liste
+
+Comment faire si je veux créer plusieurs comptes utilisateur sur chaque machine ?
+
+Voir fichier setup_4.yml et host_vars/centos1.formation.opendoor.fr
+
+### Atelier 5 - variables de type tableau associatif
+
+Comment faire si je veux que ces comptes utilisateurs aient des mots de passe et des groupes différents ?
+
+Voir fichier setup_5.yml et host_vars/centos1.formation.opendoor.fr
+
+⚠️ pour que la solution fonctionne, il faut que le fichier répertoire host_vars et son contenu (centos1.formation.opendoor.fr) soit dans le même répertoire que votre fichier d'inventaire.
 
-Il suffit de changer la valeur de la variable.
