Ich arbeite an einer AWS-Cloud-Vorlage, die einen Opsworks-Stapel erstellt. In meinem Stapel habe ich eine Instanz (Ubuntu 14.04), alle Anwendungen und Pakete, die in der Instanz installiert werden, werden im Kochkochbuch aus einem S3-Bucket konfiguriert. Ich brauche eine Umgebungsvariable in meinem Beispiel zu setzen und sein Wert ist durch einen Parameter der Cloudformation-Vorlage festgelegt wird, ist dies die Vorlage:Legen Sie eine Umgebungsvariable in der benutzerdefinierten JSON in opsworks

Ich mag meine Instanz diese Umgebungsvariable haben:
export $Apps_ENV = "test"/"int"/"prod"
so hängt der Wert davon ab, was der Benutzer auswählen wird. Wie setze ich diese Variable? Ist es möglich durch CustomJson? Oder direkt im Kochbuch? bitte hilfe. Vielen Dank.
'CustomJson' ist eine Eigenschaft der Ressource' AWS :: Opsworks :: Stack', die Chef verwendet. – JavaQueen
