使用依赖性预配访问策略

Question

我正在尝试执行以下操作：

• 创建密钥保管库(工作(
• 创建可用区函数(有效(
• 使用密钥保管库的 vaultURI 作为可用区函数的应用设置(有效(
• 为 AZ 函数提供托管标识(有效(
• 创建一个访问策略，使可用区功能可以访问密钥保管库(哎呀！

最初，我在密钥保管库中创建访问策略，但我必须将 AZ 函数声明为依赖于密钥保管库(以便我可以获取其 URI(。显然，我无法将密钥保管库设置为依赖于 AZ 函数(因为这会创建循环依赖项(。然后，我尝试创建访问策略作为另一个步骤，并将其标记为依赖于密钥保管库和可用区函数(认为它将最后配置(。

但出于某种原因，在查看部署日志时，他似乎总是试图先部署它！任何帮助将不胜感激。

Answer 1

你的模板绝对没问题，所以如果这不起作用，它看起来像一个错误。 话虽如此，您始终可以通过将accessPolicy分配移动到嵌套模板中来解决此问题：

{
"type": "Microsoft.Resources/deployments",
"apiVersion": "2018-05-01",
"name": "linkedTemplate",
"dependsOn": [
"[variables('keyVaultName')]",
"[variables('functionName')]"
],
"properties": {
"mode": "Incremental",
"templateLink": {
"uri":"https://mystorageaccount.blob.core.windows.net/AzureTemplates/newStorageAccount.json",
"contentVersion":"1.0.0.0"
},
"parameters": {
"managedIdentityId":{"value": "[reference(concat(resourceId('Microsoft.Web/sites', variables('functionName')), '/providers/Microsoft.ManagedIdentity/Identities/default'), '2015-08-31-PREVIEW').principalId]"}
}
}

您需要将模板上传到某处(其中应仅包含您的accessPolicy作业

尝试从 reference(( 函数中删除 apiVersion，这应该会将调用延迟到预配资源之后。 例如

[reference(concat(resourceId('Microsoft.Web/sites', variables('functionName')), '/providers/Microsoft.ManagedIdentity/Identities/default')).principalId]"
