问题描述
在我的公司，我们的应用程序具有相同的环境:IT、ST、AT 和 PRD.我们使用 Terraform 来部署我们的 Azure 资源，目前正在尝试设置一个 API 管理解决方案，将调用传递给 Function App 后端.
In my company we have identical environments for our application: IT, ST, AT and PRD. We use Terraform to deploy our Azure resources, and are currently attempting to set up an API management solution which passes calls to a Function App backend.
设置相当简单，我们声明了一系列 API，并在它们的后端策略中声明了这一点:
The set up is fairly simple, we have a series of APIs declared, and in their backend policies we declare this bit:
<policies>
<inbound>
<set-backend-service id="apim-generated-policy" backend-id="function-at" />
</inbound>
</policies>
在 IT/ST 中，我们已经能够成功设置它.但是，当我们的 Terraform 管道在 AT 上运行时，它总是无法更新我们的 API，并出现以下错误:
In IT/ST we have been able to set this successfully. However, when our Terraform pipeline runs on AT, it always fails to update our APIs with this error:
Error: Error creating or updating API Operation Policy (Resource Group "rg-at" / API Management Service "api-at" / API "call" / Operation "get-call"):
apimanagement.APIOperationPolicyClient#CreateOrUpdate: Failure responding to request:
StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="ValidationError" Message="One or more fields contain incorrect values:" Details=[{"code":"ValidationError","message":"Error in element 'set-backend-service' on line 3, column 6: Backend with id 'function-at' could not be found.","target":"set-backend-service"}]
尝试在 Azure UI 中手动添加此行时，会出现同样的错误:
When attempting to add this line manually in the Azure UI, the same error occurs:
Error in element 'set-backend-service' on line 3, column 10:
Backend with id 'function-at' could not be found.
我不明白为什么这拒绝工作.该函数存在并且与 API 管理器位于同一资源组中.我最好的猜测是有人在其他环境中手动更改了未反映在 Terraform 代码中的设置.我该如何解决这个问题?我对 ST 和 AT API/函数进行了并排比较，没有发现任何明显差异.
I cannot understand why this refuses to work. The function exists and is in the same resource group as the API manager. My best guess is that someone has changed a setting manually in the other environments that is not reflected in the Terraform code. How can I go about troubleshooting this issue? I did a side-by-side comparison of the ST and AT APIs/functions and did not find any obvious differences.
提前感谢您的帮助！
推荐答案
我在 Terraform 部署过程中遇到了同样的问题，对我来说解决方案是添加 api_management_backend 并且在政策中我能够参考它.
I faced the same problem during Terraform deployment and for me solution was to add api_management_backend and in policy I was able reference to it.
