如何使用 ARM 模板创建自动化任务“删除旧的 blob”？

Question

在 Azure 门户中从我的 Azure 存储帐户创建“删除旧 blob”自动化任务后，我获得了 2 个资源：一个 LogicApp 和一个自动称为“azureblob-MyStorageName”的 API 连接。

我导出了LogicApp的ARM模板，重新从头创建了LogicApp。但部署失败。

ARM模板到此结束：

"parameters": {
    "$connections": {
        "value": {
            "azureblob": {
                "id": "/subscriptions/xxx-xxx-xxx-xxx/providers/Microsoft.Web/locations/francecentral/managedApis/azureblob",
                "connectionName": "azureblob-mystorageaccountname",
                "connectionId": "[resourceId('Microsoft.Web/connections', 'azureblob-mystorageaccountname')]"
            }
        }
    }
}

我收到此错误：

Error:The managedBy resource id is missing in workflow 'CleanBlob-Daily'. ManagedBy must be provided if resource kind is 'AutomationTask'. Click here for details

在这篇 Microsoft 文章 Microsoft.Weblocations/managedApis 中，它说使用引用来创建 Api 连接，但由于处于只读状态而无法部署。

不过这端的ARM模板使用参考：

"parameters": {
    "$connections": {
        "value": {
            "azureblob": {
                "id": "[reference(resourceId('Microsoft.Web/locations/managedApis', '{azureblob}'), '2016-06-01')]",
                "connectionName": "[parameters('apiConnectionName')]",
                "connectionId": "[resourceId('Microsoft.Web/connections', 'azureblob-kpmgfrsasbxdocs0002')]"
            }
        }
    }
}

我收到此错误：

Deployment template validation failed: 'The template resource 'CleanBlob-Daily' at line '1' and column '1335' is not valid: Unable to evaluate template language function 'resourceId': the type 'Microsoft.Web/locations/managedApis' requires '2' resource name argument(s). Please see https://aka.ms/arm-resource-functions/#resourceid for usage details.. Please see https://aka.ms/arm-functions for usage details.'. (Code: InvalidTemplate)

那么，如何使用 ARM 创建“删除旧 blob”自动化任务？

Answer 1

我使用从 Delete old blobs 自动化任务生成的代码创建了一个新的逻辑应用程序，并对其进行了一些修改。我正在使用 ARM 模板部署它。

请添加您的连接参数。我已使用

az deployment group create --resource-group <resourceGroup_Name> --template-file <ARM_File_Name.json>

命令进行部署。

我已经取得了成功的结果。
