Azure Resource Template-Abhängigkeiten/Anwendungseinblicke

Question

Ich habe ein Henne-und-Ei-Problem bei der Bereitstellung von Application Insights mit meiner Webanwendung für Azure. In der ARM-Vorlage hängt das Application Insights-Modul von der Website für die Anwendungs-ID ab (siehe Abhängigkeiten in den folgenden ARM-Vorlagen). Um die Webanwendung vollständig zu instrumentieren, benötige ich andererseits den Instrumentierungsschlüssel aus dem Application Insights Module. Wie kommt man damit klar?

Praktische Anwendung Ansicht vom Portal

ARM Vorlage für Web App

ARM Vorlage für Praktische Anwendung

Answer 1

Die Lösung besteht darin, die Verbindungszeichenfolgen und App-Einstellungen als verschachtelte untergeordnete Ressourcen der Website zu erstellen. Durch die Verwendung der untergeordneten Ressourcenstrategie kann man dann die Anwendungseinstellungen sowohl von den Anwendungsinformationen der Website als auch von abhängig machen. Dies ermöglicht die Bereitstellung in der folgenden Reihenfolge auftreten:

1. Web Site
2. Praktische Anwendung
3. Web Site config/appSettings

Die beiden folgenden Antworten waren hilfreich. Der erste zeigt, wie man den Instrumentationsschlüssel zieht. Das zweite Beispiel veranschaulicht, wie App-Einstellungen und Verbindungszeichenfolgen als untergeordnete Ressourcen der Website verschachtelt werden.
