azure - 将 VM 规模集附加到应用程序网关的后端池

Question

谁能提供一个示例，说明如何使用 Terraform 将 Azure VM 规模集 (VMSS) 添加到应用程序网关的后端池。

我只能找到one example我无法为自己工作。尽管 terraform plan 和 terraform apply 不会出错，但 VMSS 不会添加到后端池中。我想知道我的问题是否是由于应用程序网关资源的 backend_address_pool 输出是一个 block 而不是单个属性引起的。

我正在使用 Terraform 0.12.5 和 AzureRM 提供程序 1.31.0。

应用程序网关资源输出:

output "name" {
  value = azurerm_application_gateway.pool[*].name
}

output "id" {
  value = azurerm_application_gateway.pool[*].id
}

output "backend_address_pool" {
  value = azurerm_application_gateway.pool[*].backend_address_pool
}

VMSS 模块声明:

module "vmss_example" {
...
application_gateway_backend_address_pool_ids = ["${module.app_gateway_example[0].id}/backendAddressPools/my-backend-address-pool"]
}

创建资源后，重新运行 terraform plan 想要更改 vmss:

...
- ip_configuration {
              - application_gateway_backend_address_pool_ids = [] -> null
              - application_security_group_ids               = [] -> null
              - load_balancer_backend_address_pool_ids       = [] -> null
              - load_balancer_inbound_nat_rules_ids          = [] -> null
              - name                                         = "ipconfig" -> null
              - primary                                      = true -> null
              - subnet_id                                    = "/subscriptions/#########-####-####-####-############/resourceGroups/demo-modules-rg/providers/Microsoft.Network/virtualNetworks/vnetdemodemo01/subnets/subnetdemovm01" -> null
            }
...

至:

...
+ ip_configuration {
              + application_gateway_backend_address_pool_ids = (known after apply)
              + application_security_group_ids               = []
              + load_balancer_backend_address_pool_ids       = []
              + load_balancer_inbound_nat_rules_ids          = (known after apply)
              + name                                         = "ipconfig"
              + primary                                      = true
              + subnet_id                                    = "/subscriptions/#########-####-####-####-############/resourceGroups/demo-modules-rg/providers/Microsoft.Network/virtualNetworks/vnetdemodemo01/subnets/subnetdemovm01"
            }
...

我认为这意味着它正在尝试更新application_gateway_backend_address_pool_ids。

如有任何帮助、指点或建议，我们将不胜感激。 TIA

是的，您只需使用 application_gateway_backend_address_pool_ids 指定对 ip_configuration 中应用程序网关的后端地址池的引用数组。堵塞。

例如，这在我这边适用于 Terraform v0.12.5+provider.azurerm v1.32.0:

ip_configuration {
  name                                   = "TestIPConfiguration"
  primary                                = true
  subnet_id                              = "${azurerm_subnet.backend.id}"
  application_gateway_backend_address_pool_ids = "${azurerm_application_gateway.network.backend_address_pool[*].id}"
}

或者，这也有效 application_gateway_backend_address_pool_ids = ["${azurerm_application_gateway.network.backend_address_pool[0].id}"]

检查输出

output "backend_address_pool" {
    value = "${azurerm_application_gateway.network.backend_address_pool[*].id}"
}
