azure - 流分析作业部署为 Azure 资源管理器 (ARM) 模板

Question

我正在尝试为定义为 JSON 模板的流分析作业设置一个输出 EventHub。如果没有输出位，模板将成功部署，但是在添加输出定义时会失败，并显示:

Deployment failed. Correlation ID: <SOME_UUID>. {
    "code": "BadRequest",
    "message": "The JSON provided in the request body is invalid. Property 'eventHubName' value 'parameters('eh_name')' is not acceptable.",
    "details": {
        "code": "400",
        "message": "The JSON provided in the request body is invalid. Property 'eventHubName' value 'parameters('eh_name')' is not acceptable.",
        "correlationId": "<SOME_UUID>",
        "requestId": "<SOME_UUID>"
    }
}

我将 ARM 模板定义为:

{
    "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",

            }],

                        "properties": {
                            "eventHubName": "parameters('eh_name')",
                            "serviceBusNamespace": "parameters('eh_namespace')",
                            "sharedAccessPolicyName": "RootManageSharedAccessKey"
                        }

                        }
                    }
                }
            }]
        }
    }]
}

在这里检查https://learn.microsoft.com/en-us/azure/templates/microsoft.streamanalytics/streamingjobs看起来输出的 JSON 结构与预期一致(具有 properties 字段以及 type)。

我已经使用开发人员工具从 Chrome 浏览器中找出了这些“事件中心属性”，并检查了 HTTP 请求“GetOutputs”的详细信息，否则我不确定在哪里可以看到如何指定这些属性？该结构看起来与输入 IoT 中心(正在运行)的结构非常相似，在这种情况下，对与 IoT 中心详细信息相关的属性使用不同的标签。

查看这篇博文https://blogs.msdn.microsoft.com/david/2017/07/20/building-azure-stream-analytics-resources-via-arm-templates-part-2-the-template/输出部分与 PowerBI 相关，并且看起来属性使用了不同的结构:outputPowerBISource，因此我尝试将字段 outputEventHubSource 用于事件中心(来自使用 Chrome 开发者工具的检查)而不是 properties，但随后我收到此错误:

Deployment failed. Correlation ID: <SOME_UUID>. {
    "code": "BadRequest",
    "message": "The JSON provided in the request body is invalid. Required property 'properties' not found in JSON. Path '', line 1, position 1419.",
    "details": {
        "code": "400",
        "message": "The JSON provided in the request body is invalid. Required property 'properties' not found in JSON. Path '', line 1, position 1419.",
        "correlationId": "<SOME_UUID>",
        "requestId": "<SOME_UUID>"
    }
}

我用来部署此模板的命令是 Azure CLI(来自 Linux Debian 计算机):

az group deployment create \
  --name "deployStreamAnalyticsJobs" \
  --resource-group "MyRGName" \
  --template-file ./templates/stream-analytics-jobs.json

如何在 Azure 资源管理器 (ARM) 模板中为流分析作业指定输出？

Answer 1

任何包含参数的属性(或任何需要计算的表达式都必须包含方括号，例如

"eventHubName": "[parameters('eh_name')]",
"serviceBusNamespace": "[parameters('eh_namespace')]",

否则使用引号中的文字值。

有帮助吗？
