在功能端点上使用ARM创建Eventgrid订阅

标签: azure azure-resource-manager azure-eventgrid

我正在尝试使用ARM模板在Azure存储帐户上创建Eventgrid订阅。在门户中手动创建它并进入高级设置,产生了以下模板。我进一步向其中添加了所需的模板项目(例如架构),但它始终会产生错误。我尝试过在线寻找相似的模板,但是似乎无法使用"endpointType": "AzureFunction"找到任何模板。同样,在资源浏览器中也没有提到可以进一步帮助我的部署。

任何人都可以帮助我解决问题吗?

在创建过程中从门户网站生成的模板:

{
    "name": "test123",
    "properties": {
        "topic": "/subscriptions/<guid>/resourceGroups/<myGroup>/providers/Microsoft.Storage/storageAccounts/<myStorageAccount>",
        "destination": {
            "endpointType": "AzureFunction",
            "properties": {
                "resourceId": "/subscriptions/<guid>/resourceGroups/<myGroup>/providers/Microsoft.Web/sites/<myFunctionsApp>/functions/<myFunction>",
                "maxEventsPerBatch": 1,
                "preferredBatchSizeInKilobytes": 64
            }
        },
        "filter": {
            "includedEventTypes": [
                "Microsoft.Storage.BlobCreated"
            ],
            "advancedFilters": [
                {
                    "operatorType": "StringContains",
                    "key": "Subject",
                    "values": [
                        "-original"
                    ]
                }
            ]
        },
        "labels": [],
        "eventDeliverySchema": "EventGridSchema"
    }
}

我一直试图通过Azure工具链(ARM模板/ CLI / REST)中的任何选项来做完全相同的事情。我查看了Portal的调用,发现它正在使用您显示的2020-01-01-preview EventGrid API。

经过一些测试,我可以确认新的API允许部署具有AzureFunction的EndpointType的订阅,如下所示:

{
  "name": "[concat(variables('eventDomainName'), '/Microsoft.EventGrid/', variables('subscriptionName'))]",
  "type": "Microsoft.EventGrid/domains/providers/eventSubscriptions",
  "location": "[variables('location')]",
  "apiVersion": "2020-01-01-preview",
  "properties": {
    "destination": {
        "endpointType": "AzureFunction",
        "properties": {
            "resourceId": "[resourceId('Microsoft.Web/sites/functions/', parameters('functionAppName'), parameters('functionName'))]"
        }
    },
    "filter": "[parameters('subscriptionProperties').filter]"
  }
}

似乎您的问题与尝试定位AzureFunction无关,并且您使用的是正确的API版本,因此事实并非如此。

我认为问题在于您的“类型”值。我认为应该采用以下格式:// providers / eventSubscriptions

所以应该是Microsoft.Storage/storageAccounts/providers/eventSubscriptions。

我不认为endpointType中有单独的AzureFunctiondocumented。这只是Webhook处理程序的特例。

GitHub Repo包含一个示例ARM模板,您可以参考。这是您需要的确切代码段

...
"destination": {
    "endpointType": "WebHook",
    "properties": {
        "endpointUrl": "[concat(variables('functionUrl'), listKeys(resourceId('Microsoft.Web/sites/host/', variables('functionAppName'), 'default'),'2016-08-01').systemkeys.eventgrid_extension)]"
    }
}
...
