Azure ARM根據輸入參數部署App Service Plan

Question

我正在嘗試創建一個包含App Service計划和App Service的ARM模板，但是如果未設置參考現有App Service計划的可選參數，則僅在其中創建App Service計划的模板。

因此，ARM應該僅使用作為參數給出的現有App Service計划為App Service創建一個App Service計划。

那怎么可能呢？

解

這是有效的壓軸ARM模板

在您的情況下，您應該向dependsOn添加dependsOn屬性：

dependsOn: [
    "[variables('serviceplanName')]"
]

這樣，如果需要創建它，它將等待它完成。
