Dépendances d'un modèle de ressources Azure/Insights d'application

Question

J'ai rencontré un problème de poule et d'oeuf qui a déployé Application Insights avec mon application Web dans Azure. Dans le modèle ARM, le module Application Insights dépend du site Web de l'ID de l'application (voir les dépendances dans les modèles ARM ci-dessous). D'un autre côté, pour instrumenter complètement l'application web, j'ai besoin de la clé d'instrumentation du module Application Insights. Comment peut-on contourner cela?

Insights application Vue depuis le Portail

modèle ARM pour le Web App

ARM Modèle pour l'application Insights

Answer 1

La solution consiste à créer les chaînes de connexion et les paramètres d'application en tant que ressources enfants imbriquées du site Web. En utilisant la stratégie des ressources enfant, on peut alors faire dépendre les appsettings à la fois du site Web et des aperçus d'application. Cela permet à l'approvisionnement de se produire dans l'ordre suivant:

1. Site Web
2. Insights application
3. Site Web config/appsettings

Les deux réponses suivantes ont été utiles. Le premier illustre comment tirer la clé d'instrumentation. La seconde illustre comment imbriquer les paramètres de l'application et les chaînes de connexion en tant que ressources enfants du site Web.
