如何在函数应用的 ARM 模板中引用现有存储帐户

Question

我想使用 ARM 模板创建一个函数应用，以便 ARM 模板引用现有存储帐户（此模板中的“onestoragebo”），而不是创建新的。贮存。在 ARM 模板下部署时出现以下错误。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。使用详情请参阅https://aka.ms/arm-template-expressions/#reference。'。

Answer 1

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

从逻辑上考虑：如果模板中没有定义资源，如果资源不存在怎么办？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。参考listKeys文档；当资源未在同一个模板中定义时，您必须使用资源 ID，而不是资源名称。

Answer 2

通过在存储帐户资源中添加 "mode":"Incremental" 属性，我已设法使用现有存储帐户部署函数应用。附加了新的 ARM 文件。如果有人知道更好的解决方案，请发表评论。
