如何将输出从一个模块传递到另一个模块?

How to pass Outputs from One Module to another?

我有两个模块。

  1. 一个叫module-azure-vnet
  2. 第二个被称为module-azure-vm-instance-zabbix-proxy

我想将模块 module-azure-vnet 的输出传递给模块 module-azure-vm-instance-zabbix-proxy。第一个模块工作正常,但第二个模块需要子网、安全组和路由的输入。

main.tf

module "module-azure-vnet-dtap" {
  source = "/Users/username/project/module-azure-vnet-dtap"
}

variable "subnets_id_wan" {}

module "module-azure-vm-instance-zabbix-proxy" {
  source = "/Users/username/project/module-azure-vm-instance-zabbix-proxy"
  azurerm_subnet = "${module.module-azure-vnet-dtap.azurerm_subnet.wan.id}"
}

Error: resource 'azurerm_network_interface.no_public_ip' config: unknown resource 'azurerm_subnet.wan' referenced in variable azurerm_subnet.wan.id

Error: resource 'azurerm_network_security_rule.security_rule_default' config: unknown resource 'azurerm_network_security_group.wan' referenced in variable azurerm_network_security_group.wan.name

Error: module "module-azure-vm-instance-zabbix-proxy": "azurerm_subnet" is not a valid argument

在模块 module-azure-vnet-dtap

resource "azurerm_subnet" "wan" {
  count                     = "${var.enable_wan_subnet ? 1 : 0}"
  provider                  = "azurerm.base"
  name                      = "${format("%s-%s-%s", var.environment_name, "WAN", "Subnet")}"
  virtual_network_name      = "${azurerm_virtual_network.this.name}"
  resource_group_name       = "${azurerm_resource_group.this.name}"
  address_prefix            = "${cidrsubnet(var.cidr_block,5,count.index)}"
  route_table_id            = "${azurerm_route_table.wan.id}"
  network_security_group_id = "${azurerm_network_security_group.wan.id}"
}

resource "azurerm_network_security_group" "wan" {
  count               = "${var.enable_wan_subnet ? 1 : 0}"
  provider            = "azurerm.base"
  name                = "${format("%s-%s", var.environment_name, "WAN-Subnet-Security-Group")}"
  location            = "${azurerm_resource_group.this.location}"
  resource_group_name = "${azurerm_resource_group.this.name}"
}

output "subnets_id_wan" {
  value = "${azurerm_subnet.wan.*.id}"

  depends_on = [
    "azurerm_subnet.wan",
  ]
}

你应该像这样引用输出:

"${module.MODULE_NAME.OUTPUT_NAME}"

在你的情况下应该是:

"${module.module-azure-vnet-dtap.subnets_id_wan}"

此外,您只能访问输出,不能访问模块中的资源 (afaik)。

我自己找到了解决方案,这是连接两个模块所需的整个结构。

在 VNET 模块示例中设置变量:

variable "resource_group_name" {
      default     = "default_resource_group"
      }

      variable "region_name" {
      default     = "ukwest"
      }

声明输出:

output "security_groups_id_wan" {
      value = "${element(concat(azurerm_network_security_group.wan.*.id, list("")),0)}"

        depends_on = [
          "azurerm_subnet.wan",
          ]
      }

你需要 zabbix proxy 模块中的变量来接收值>

variable "resource_group_name" {
        default = ""
        }
        variable "resource_group_location" {
        default = ""
        } 

并且在外部文件夹中 main.tf 用于模块>

module "module-azure-vm-instance-zabbix-proxy" {
        source = "/Users/username/project/module-azure-vm-instance-zabbix-proxy"
        resource_group_name = "${module.module-azure-vnet-dtap.resource_group_name}"
        resource_group_location = "${module.module-azure-vnet-dtap.resource_group_location}"
        subnets_id_wan = "${module.module-azure-vnet-dtap.subnets_id_wan}"
        security_groups_name = "${module.module-azure-vnet-dtap.security_groups_name_dmz}"
        environment_name = "${module.module-azure-vnet-dtap.environment_name}"
      }

      module module-azure-vnet-dtap {
        source = "/Users/username/project/module-azure-vnet-dtap"
      }
