输出的地形条件

Question

子网名称将根据 env 是非 prod 还是 prod 而有所不同。不能同时使用基于计数和 for_each 的引用错误。

需要以下两项之一：仅当 env 是 prod 时才执行资源块？或者 output.tf 如果未从资源中找到值则忽略错误。

 resource "azurerm_subnet" "subnet" {
     count               = var.environment == "prd" ? 1 : 0 //execute block only if env is prod
      for_each             = var.subnet_names
      name                 = join("",["test-","${var.environment}",each.key,"-snet"])
      resource_group_name  = azurerm_virtual_network.vnet.resource_group_name
      virtual_network_name = azurerm_virtual_network.vnet.name
      address_prefixes     = tolist(each.value) 
      }

Variables.tf

variable "subnet_names" {
  description = "subnet names"
  default = {}
  type        = map

}

variable "environment" {
  description = "Name of prod environment"
  default     = "prd"
}

tf变量：

subnet_names = {
   "s1-uat" = ["20.0.0.0/27"] ,
   "s1-qa" = ["20.0.0.32/27"] ,
  "s2-qa" = ["20.0.0.64/27"] ,
   "s2-uat" = ["20.0.0.96/27"]
}


environment = "prd"

output.tf

 "s1_subnet_name" {
  value       = azurerm_subnet.subnet["s1-uat"].name
  depends_on = [
azurerm_subnet.subnet
]
}

错误： “count”和“for_each”元参数是互斥的，只有一个应该用于明确要创建的资源数量。

您只能使用计数或 for_each。所以你可以试试这个：

resource "azurerm_subnet" "subnet" {
     count               = var.environment == "prd" ? length(var.subnet_names) : 0      
      name                 = join("",["test-","${var.environment}",each.key,"-snet"])
      resource_group_name  = azurerm_virtual_network.vnet.resource_group_name
      virtual_network_name = azurerm_virtual_network.vnet.name
      address_prefixes     = tolist(each.value) 
      }

对于名称和 address_prefixes 而不是使用 'each' 您可以使用 count.index 。在 terraform count 中不支持 each
