问题描述
我正在构建一个用于部署 Web 应用程序、sql 数据库和密钥保管库的 arm 模板.
Web 应用程序将使用
1- 系统身份(将用于访问密钥库).
2- 到将使用密钥库访问方式的 sql 数据库的连接字符串:
@Microsoft.KeyVault(SecretUri=https://', parameters('keyVaultName'),'.vault.azure.net/secrets/connectionString)')
将使用
部署密钥库1 - 上述 web 应用程序的访问策略.
2 - 包含连接字符串的秘密(在部署时在管道中构建).
webapp 需要在 keyvault 之前部署，所以当 keyvault 部署时，它可以找到 webapp 身份，从而为其创建访问策略.
但是我用这种方法遇到的问题是，当连接字符串作为 webapp 的一部分添加时，keyvault 还不存在，所以 @Microsoft.KeyVault 访问秘密的方式不起作用，即使部署密钥库后，我得到以下
但是如果我删除连接字符串并在部署后手动添加它，保持完全相同的值，它就可以工作.
如何部署包含 keyvault 访问方式的连接字符串，Web 应用程序满意并且可以访问其中的连接字符串?
我认为问题很清楚，不需要包含模板，但如果您确实需要查看，请发表评论并将添加到问题中.

(正确设置 Keyvault 引用)
(保险柜访问策略也已正确设置)
I am building an arm template that deploys a web app, sql database and a key vault.
The web app will be deployed with
1- System identity (which will be used to access the keyvault).
2- Connection string to the sql database that would be using the keyvault access way:
@Microsoft.KeyVault(SecretUri=https://', parameters('keyVaultName'),'.vault.azure.net/secrets/connectionString)')
The keyvault will be deployed with
1 - Access policy for the webapp above.
2 - Secret that contains the connection string (constructed in the pipeline while deploying).
The webapp needs to be deployed before the keyvault, so when the keyvault is deployed, it can find the webapp identity so it creates the access policy for it.
But the issue I am having with this approach is that when the connection string added as part of the webapp, the keyvault doesn't exist yet, so that @Microsoft.KeyVault way of accessing the secret doesn't work, even after the keyvault is deployed, and I get the below
But if I remove the connection string and add it manually after the deployment, keeping the exact same value, it works.
How can I deploy the connection string containing the keyvault access way where the webapp is happy and can access the connection string in it?
I think the problem is clear and no need to include the template, but if you do need to look please leave a comment and will add to the question.
EDITTemplate
You can use depends on condition on keyvault . I created a Keyvault first and added
"dependsOn": [
"[resourceId('Microsoft.Web/sites', parameters('appBaseName'))]"
while setting the access policies.
So the complete template will be :
