Terraform私有天蓝色负载均衡器问题

Question

Iam试图使用私有负载平衡器部署基础设施：

.....
resource "azurerm_lb" "private" {
name                = "${var.name}-${var.live}-private-lb"
location            = data.azurerm_resource_group.rg.location
resource_group_name = data.azurerm_resource_group.rg.name
sku                 = var.sku

frontend_ip_configuration {
  name                          = "frontend"
  subnet_id                     = var.subnet_id != "" ? var.subnet_id : null
  private_ip_address            = (var.subnet_id != "" && var.private_ip != "") ? var.private_ip : null
  private_ip_address_allocation = var.subnet_id != "" ? (var.subnet_id == "" ? "Static" : "Dynamic") : null
 }
}
......

但我收到了错误信息：

..../frontendIPConfigurations/frontend must reference either a Subnet, Public IP Address or Public IP Prefix." Details=[]

我为何及如何处理这个问题？我不知道缺少哪种配置。谢谢

内部负载均衡器与公共负载均衡器不同，它被分配给子网，并且没有公共IP地址。当显示错误时，前端应该引用或a子网、公共IP地址或公共IP前缀，并且在引用时子网应该已经存在。您可以使用数据源子网来访问有关现有资源的信息，或者为负载均衡器创建子网和VNet。

例如，下面的内容可以适用于我。

data "azurerm_resource_group" "rg" {
  name     = "mytestrg" 
}


variable "sku" {
  default = "basic"
}

variable "private_ip" {
  default = "172.19.0.100"
}

variable "env" {
  default="Static"
}

data "azurerm_subnet" "test" {
  name                 = "default"
  virtual_network_name = "vnet1"
  resource_group_name  = "${data.azurerm_resource_group.rg.name}"
}

resource "azurerm_lb" "test" {
  name                = "mytestlb"
  location            = "${data.azurerm_resource_group.rg.location}"
  resource_group_name = "${data.azurerm_resource_group.rg.name}"
  sku                 = "${var.sku}"

  frontend_ip_configuration {
    name                          = "frontend"
    subnet_id                     = "${data.azurerm_subnet.test.id}"
    private_ip_address            = "${var.env=="Static"? var.private_ip: null}"
    private_ip_address_allocation = "${var.env=="Static"? "Static": "Dynamic"}"
  }
}
