json - 如何在 ARM 模板的标签对象类型中使用 utcNow()

Question

我在资源标签中使用 utcNow()，但我没有获取日期和时间，而是再次获取“[utcNow()]”。以下是我使用 Arm 模板的格式。

ARM 模板参数:

"resourceTags": {
      "type": "object"
    }

parameters.json 值:

"resourceTags": {
      "value": {
        "criticality": "Tier1",
        "applicationName": "Devzone",
        "owner": "abcd",
        "costCenter": "1234",
        "contactEmail": "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="39585b5a5d795e54585055175a5654" rel="noreferrer noopener nofollow">[email protected]</a>",
        "dataClassification": "Confidential",
        "environment": "Dev",
        "CreatedDate": "[utcNow()]"
      }
    }

我尝试在管道变量组中使用。仍然得到相同的“[utcNow()]”而不是值。

我做错了什么？如何替换 utcNow()？

Answer 1

根据 documentation ，您只能使用 utcNow() 函数作为参数的默认值。

The function isn't allowed in other parts of the template because it returns a different value each time it's called. Deploying the same template with the same parameters wouldn't reliably produce the same results.

这就是给定你的对象的样子

"resourceTags": {
      "type": "object",
      "defaultValue" : {
        "criticality": "Tier1",
        "applicationName": "Devzone",
        "owner": "abcd",
        "costCenter": "1234",
        "contactEmail": "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="e081828384a0878d81898cce838f8d" rel="noreferrer noopener nofollow">[email protected]</a>",
        "dataClassification": "Confidential",
        "environment": "Dev",
        "CreatedDate": "[utcNow()]"
      }
    }

但是，如果您为参数提供值，则整个对象将被覆盖。因此，您不需要将其设置在那里，而是需要将对象的值分成单独的参数。对于 CreatedDate 参数，请设置默认值那里，并且不要在管道中提供该值。然后将标签设置为参数。

"CreatedDate": "[parameters('utcNow')]"
