# Ce script vérifie la disponibilité de plusieurs applications web définies
|
||||
# dans le fichier .env.
|
||||
#
|
||||
# Fonctionnement global :
|
||||
# 1. charge la configuration depuis le fichier .env ;
|
||||
# 2. vérifie que le DNS du site est résolu ;
|
||||
# 3. effectue une requête HTTP avec curl ;
|
||||
# 4. analyse le code HTTP retourné ;
|
||||
# 5. écrit le résultat dans un fichier de log local ;
|
||||
# 6. envoie une notification Discord avec l’état du service.
