azure SQL 带副本的数据库导入

Question

我正在开发一个 ARM 模板，该模板将要求以逗号分隔的数据库名称列表，然后使用 copyIndex 函数创建它们。这方面工作很好，但我的解决方案的下一步不是。接下来我想做的是为每个数据库导入一个 .bacpac 文件，以便在完成后可以使用。

验证错误表明问题出在 Import 资源 dependsOn 中的 concat 函数。我已经用几种不同的方法对其进行了测试，但看不出哪里错了。

我看到的确切错误消息是....

Unable to process template language expressions for resource '/subscriptions/xxxxxx-xxxxx-xxxxxx-xxxxx/resourceGroups/testGroup/providers/Microsoft.Sql/servers/testsql/databases/CustomersDB/extensions/import' at line '858' and column '10'. 'The provided parameters for language function 'concat' are invalid. Either all or none of the parameters must be an array.

**添加了整个模板

Answer 1

据我所知，我们不能在嵌套资源中使用copyindex函数。

如果你运行你的手臂模板，你会遇到这个错误：

Copying nested resources is not supported. Please see https://aka.ms/arm-copy/#looping-on-a-nested-resource for usage details.'.

所以我建议你将嵌套资源作为根资源移动到arm模板中。然后你可以使用copyindex.

更多细节，您可以参考下面的arm模板：

注意：将参数 orb 替换为您的数据库名称。

结果：

我也测试了你的模板，我发现你在导入扩展中的存储 url 有问题。我用主存储密钥和 url 更改了它。效果不错。
