地形 :如何将一个模块的输出值传递给 azure 中的另一个模块

Question

环境文件夹设置：

• 模块 A 包含用于在 Azure 上创建资源组rg.tf文件。
• 模块 B 包含vnet.tf文件，它需要模块 A 中的资源组名称。

如何将一个输出使用到另一个？

Terraform -v = Terraform v0.12.6

文件夹结构 ：

C:TerraformResourceGroup
rg.tf 
var.tf
output.tf
C:TerraformVnet
vnet.tf 

rg.tf包含：

provider "azurerm" { 
Subscription ID : xxxxxxxxxxxxxx
Subscription Name :xxxxxxxxxxxxx
Client ID : xxxxxxxxxxxxxxxxx
Client Secret: xxxxxxxxxxxx
}
terraform {
backend "azurerm" {
storage_account_name  = xxxxxxxxxxxxx
resource_group_name   = xxxxxxxxxxxxx
container_name        = "versiontf"
key                   = "terraform.tfstate"
}
}
resource "azurerm_resource_group" "res_group" {
location = "${var.location}"
name     = "${var.name}"
}

var.tf包含

variable "location" {
default     = "West US"
}
variable "name" {
default = "testing"
}

output.tf包含：

output "rg_name" {
value = "${azurerm_resource_group.res_group.name}"
}

vnet.tf包含：

provider "azurerm" { 
Subscription ID : xxxxxxxxxxxxxx
Subscription Name :xxxxxxxxxxxxx
Client ID : xxxxxxxxxxxxxxxxx
Client Secret: xxxxxxxxxxxx
}
resource "azurerm_virtual_network" "test" {
name                = "vnet"
location            = "east us"
resource_group_name = "????????????"  (How do i read the resource group name which i created using rg.tf)
address_space       = ["10.0.0.0/16"]
}

仅供参考：我能够创建输出值并将其添加到后端状态文件。

您只需要使用文件中的模块vnet.tf如下所示：

provider "azurerm" { 
Subscription ID : xxxxxxxxxxxxxx
Subscription Name :xxxxxxxxxxxxx
Client ID : xxxxxxxxxxxxxxxxx
Client Secret: xxxxxxxxxxxx
}
module "resourceGroup" {
source = "../ResourceGroup"
# the variable that you set for your resource group
name = "rg_name"
location = "rg_location"
}
resource "azurerm_virtual_network" "test" {
name                = "vnet"
location            = "east us"
# use the module resource group
resource_group_name = "${module.resourceGroup.rg_name}"     
address_space       = ["10.0.0.0/16"]
}
