如何解决配置多个 Azure 负载均衡器以构建前端 IP 的 Terraform 代码
我正在尝试创建一个 Azure 负载均衡器，以在 az 负载均衡器中构建多个前端 ip，该负载均衡器将公共 ip 用于 Azure 可用性区域：
这是我的文件结构：
terraform-azurem-loadbalncer/
┣ locals.tf
┣ output.tf
┣ tlz-lb.tf
┣ tlz-pip.tf
┗ variables.tf
我想要做的很像帖子[在这里][1]： 这是我的 tlz-pip.tf
resource "azurerm_public_ip" "tlz_public_ip" {
name = "${local.prefix}-${local.resource_type}-${var.pip_name}-${var.environment}"
resource_group_name = var.resource_group_name
location = var.location
allocation_method = var.allocation_method
sku = var.pip_sku
ip_version = var.ip_version
idle_timeout_in_minutes = try(var.idle_timeout_in_minutes,30)
domain_name_label = var.generate_domain_name_label ? "${local.prefix}-${local.resource_type}-${var.pip_name}-${var.environment}" : var.domain_name_label
reverse_fqdn = try(var.reverse_fqdn,null)
zones = try(var.zones,null)
tags = merge(
{
"Name" = "${local.prefix}-${local.resource_type}-${var.pip_name}-${var.environment}"
},var.tags
)
}
这是我的 tlz-lb.tf：
resource "azurerm_lb_backend_address_pool" "tlz-lb-backendpool-dev" {
count = var.nblinuxvms
name = var.backend_address_pool
loadbalancer_id = azurerm_lb.tlz-lb-navigator-dev[count.index].id
}
resource "azurerm_lb_rule" "tlz-lb-rule" {
count = var.nblinuxvms
resource_group_name = var.resource_group_name
loadbalancer_id = azurerm_lb.tlz-lb-navigator-dev[count.index].id
name = var.load_balancing_rule
protocol = "Tcp"
frontend_port = 443
backend_port = 443
frontend_ip_configuration_name = "config_${azurerm_public_ip.tlz_public_ip[count.index].name}"
}
resource "azurerm_lb_nat_rule" "tlz-nat-rule" {
count = var.nblinuxvms
resource_group_name = var.resource_group_name
loadbalancer_id = azurerm_lb.tlz-lb-navigator-dev[count.index].id
name = var.nat_rule_name
protocol = "Tcp"
frontend_port = 80
backend_port = 80
frontend_ip_configuration_name = "config_${azurerm_public_ip.tlz_public_ip[count.index].name}"
}
resource "azurerm_lb_probe" "tlz-lb-probe" {
count = var.nblinuxvms
resource_group_name = var.resource_group_name
loadbalancer_id = azurerm_lb.tlz-lb-navigator-dev[count.index].id
name = var.health_probe_name
port = 22
}
resource "azurerm_lb" "tlz-lb-navigator-dev" {
count = var.nblinuxvms
name = "${local.prefix}-${local.resource_type}-${var.environment}-${var.location}"
location = var.location
resource_group_name = var.resource_group_name
sku = var.lb_sku
frontend_ip_configuration {
name = "config_${azurerm_public_ip.tlz_public_ip[count.index].name}"
public_ip_address_id = azurerm_public_ip.tlz_public_ip[count.index].id
}
dynamic "frontend_ip_configuration" {
for_each = azurerm_public_ip.tlz_public_ip
content {
name = "config_${frontend_ip_configuration.value.name}"
public_ip_address_id = frontend_ip_configuration.value.id
}
}
}
这是我的 variables.tf:
#Public IP configuration
variable "location" {
description = "(required) The location/region where the virtual network is created"
default = "centralus"
}

description = "(required) The environment platform in which resources will be deployed."

type = map(any)
}
variable "pip_name" {

}
variable "allocation_method" {

description = "(required) Defines the allocation method for this IP address. Possible values are Static or Dynamic."

default = 30
}

}

}

default = ""
}
variable "availability_zone" {
description = "A collection containing the availability zone to allocate the Public IP in."
default = null
}
#Load Balancer
variable "lb_sku" {

description = "(Optional) The SKU of the Azure Load Balancer. Accepted values are Basic and Standard. Defaults to Basic."
}

default = "test"
description = "(required) Specifies the name of the Probe."
}
variable "nblinuxvms" {
type = number
default = "2"
description = "NUmber of VMs to be."
}
这是我得到的错误：

不知道为什么我可能会收到那个错误，因为我已经在 variables.tf 中指定了名称
解决方法
如果您查看 azurerm_lb_backend_address_pool (https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/lb_backend_address_pool) 的资源，名称是必填字段，根据您下面的代码，您将传递 var.back_address_pool 和 var.back_address_pool 的默认值为空。
resource "azurerm_lb_backend_address_pool" "tlz-lb-backendpool-dev" {
count = var.nblinuxvms
name = var.backend_address_pool
loadbalancer_id = azurerm_lb.tlz-lb-navigator-dev[count.index].id
}
