我可以在 Terraform 中为自动生成的资源选择名称吗？

Question

我正在使用 Terraform 生成 Azure Kubernetes 服务集群（以及其他东西），当我运行 Terraform 时，它会自动生成 AKS 集群使用的不同资源。我可以在 AKS 群集上选择自定义名称，但自动生成的资源接近随机名称。

有没有办法在 Terraform 中为这些自动生成的资源选择我自己的自定义名称？

示例：

resource "azurerm_kubernetes_cluster" "compute" {
    name                = "MyCluster"
    location            = "westeurope"
    resource_group_name = "my-rg"
    dns_prefix          = "something"

    linux_profile {
         admin_username = "azureuser"

    agent_pool_profile {
        name            = "default"
        count           = "1"
        vm_size         = "Standard_NC6"
        os_type         = "Linux"
   }
}

这会生成：

myCluster - Kubernetes 服务

aks-agentpool-74438003-nsg - 网络安全组

aks-agentpool-74438003-routetable - 路由表

aks-default-74438003-0 - 虚拟机

aks-default-74438003-0_OsDisk_1_5d379bc3205545e1bcd3f88ec9605- 磁盘

aks-default-74438003-nic-0 - 网络接口

aks-vnet-74438003 - 虚拟网络

default-availabilitySet-74438003 - 可用性集

例如，我可以选择是否需要 aks 前缀吗？那个重复的数字是多少？基本可以自定义这些吗？

您可以自定义其他资源的前缀或名称。
但是，仅当您自己创建这些资源并明确引用它们时。
