如何在函数应用程序的ARM模板中引用现有存储帐户

Question

我想用ARM模板创建一个函数应用程序，以便ARM模板引用现有的存储帐户(此模板中的"onestoragebo"(，而不是创建新帐户。存储在ARM模板下部署时，我收到以下错误。请帮忙！！

InvalidTemplate-部署模板验证失败："模板引用"onestoragebo"无效：找不到具有此名称的模板资源或资源副本。"。请参阅https://aka.ms/arm-template-expressions/#reference有关用法详细信息。'

我通过添加"模式"："增量">属性。将附加新的ARM文件。如果有人知道更好的解决方案，请发表评论。

Answer 2

在dependsOn块中，您指的是storageAccountName参数。没有必要那样做。根据您的问题，存储帐户名称已存在。您不能依赖ARM模板中未定义的资源。dependsOn的存在是为了确保以正确的顺序创建资源。

从逻辑上思考：如果模板中没有定义资源，那么如果资源不存在，该怎么办？它不能等待资源被创建，因为没有任何东西告诉ARM模板如何创建它

"dependsOn": [
"[resourceId('Microsoft.Web/serverfarms',variables('serverFarmName'))]"
],

您也在使用listKeys。请参阅listKeys文档；如果资源不是在同一个模板中定义的，则必须使用资源ID，而不是资源名称。
