Azure 应用网关 terraform

Question

我有一个很大的问题，我找不到解决方案或解释。

我在网上找到了这个关于应用程序网关实现的图表。

所以我尝试使用 terraform 制作它的复制品，但是我遇到了一些问题并开始提出问题，但我找不到解决方案。

这是图表

使用 terraform 我可以毫无问题地创建MainRG 、 VNET和GWSubnet ，但我想知道， MainRG内部怎么可能有包含另一个RG的AZSubnet ，这使它成为 MainRG 内部的嵌套 RG。 这是一个错误吗？

我遇到的另一个问题是如何将应用服务分配给子网？

这是我到目前为止实现的代码：

app.tf

  location            = var.app-service-loc
  name                = "ASP-hri-prd-app-service"
  resource_group_name = azurerm_resource_group.rg-hri-eur-app-service.name
  sku {
    size = "S1"
    tier = "Standard"
  }
}

resource "azurerm_app_service" "hri-prd-eur-app-testing" {
  app_service_plan_id = azurerm_app_service_plan.ASP-hri-prd-app-service.id

}

我有 2 个资源组，一个用于应用程序网关，一个用于应用程序服务。

但是我仍然不明白如何在应用程序网关资源组的子网中制作应用服务资源组。

你提出了多个问题。

• 在 Azure（MainRG 中的 RG）中不可能有嵌套的资源组。 你的图片好像有拼写错误

• 要将应用服务分配给子网，您应首先使用子网创建 VNET，然后使用 Terraform 资源azurerm_app_service_virtual_network_swift_connection创建应用服务并将其附加到子网

  name     = "example-resources"

  address_space       = ["10.0.0.0/16"]
