我有一个非常简单的带有参数的 ARM 模板 json 文件:
"StorageName": {
"type": "string",
"defaultValue": ""
},

和资源:
{
"name": "[parameters('StorageName')]",
"type": "Microsoft.Storage/storageAccounts",
"location": "[resourceGroup().location]",
"apiVersion": "2018-02-01",
"condition": "[greater(length(parameters('StorageName')), 0)]",
"sku": {
"name": "[parameters('StorageType')]"
},
"dependsOn": [],
"tags": {
"displayName": "..storage"
},
"properties": {
"accountType": "[parameters('StorageType')]",
"supportsHttpsTrafficOnly": true,
"encryption": {
"services": {
"blob": {
"enabled": true
},
"file": {
"enabled": true
}
},
"keySource": "Microsoft.Storage"
}
},
"kind": "[parameters('StorageKind')]"
}

在StorageName具有默认为空字符串值,这是基于微软的文档有效值-默认值可以是一个空字符串。
condition如果仅提供名称,我使用功能来创建存储
"condition": "[greater(length(parameters('StorageName')), 0)]",

但是当我运行这个 ARM 模板时,我仍然在 vso 控制台中收到一个错误:

任何建议如何使参数可选?
您不能使用空字符串作为资源的名称。如此合乎逻辑的解决方案,将其从空字符串更改为“false”(或任何其他值)并执行以下操作:
"[not(equals(parameters('name'), 'false'))] # << use the same value here

或者,您可以执行以下操作:
"[not(empty(parameters('name')))]"

并使用此条件部署或不部署嵌套部署,即部署存储帐户。这将起作用,因为您可以为嵌套部署使用另一个名称,但它不会启动,因为条件评估为 false。
如果\when parameter\object 不为空,这是执行某些操作的一般方法。
