# Solution (proposition)
|
## Includes et import
|
||||||
|
|
||||||
Plutôt que de conditionner chaque tâche en fonction de la distribution (ce qui sera pénible et difficile à maintenir), la solution consistant à inclure un fichier de variables propre à chaque OS cible est plus élégante.
|
**Tâche**: écrire des playbooks modulaires
|
||||||
|
|
||||||
|
**Condition**: selon besoin
|
||||||
|
|
||||||
|
**Norme**: includes et import
|
||||||
|
|
||||||
|
**Préparation**:
|
||||||
|
|
||||||
|
** Pratique **
|
||||||
|
|
||||||
|
Récupérer la solution de l'atelier handler
|
||||||
|
|
||||||
|
Identifier dans le playbook et le fichier vhost.conf toutes les spécificités de RedHat (qui vont empécher le playbook de fonctionner)
|
||||||
|
|
||||||
|
Trouver la solution à cette problématique (exécution conditionnelle, variabilisation ...)
|
||||||
|
|
||||||
|
Implémenter la solution
|
||||||
|
|
||||||
|
Sur la debian, la configuration par défaut entre en conflit avec la notre:
|
||||||
|
|
||||||
|
Modifier le playbook pour que le fichier /etc/apache2/sites-enabled/000-default.conf soit supprimé UNIQUEMENT sur la debian, avec redémarrage du service apache si besoin
|
||||||
|
|
||||||
|
|
||||||
Autre cas d'utilisation des includes:
|
** Validation:
|
||||||
|
|
||||||
```yaml
|
```bash
|
||||||
- name: ensure bootstrap role has been applied
|
curl debian1
|
||||||
include_role:
|
<span style="text-align: center;background-color: #FD5401; font-size: 42px;">Hello World</span>
|
||||||
name: bootstrap
|
|
||||||
when: apply_bootstrap_role
|
|
||||||
- include: bash.yml
|
|
||||||
tags: bash
|
|
||||||
- include: local_repo.yml
|
|
||||||
when: ansible_distribution=='CentOS' and use_local_repo
|
|
||||||
```
|
```
