Question

我有一个模块，该模块可创建具有5个子网的vNet。该模块使用块将每个子网的ID写入变量：

output "vnet_subnets" {
  description = "The ids of subnets created inside the newly created vNet"
  value       = azurerm_subnet.subnet.*.id
}

然后我使用该块将其输出到状态文件：

output "vnet_subnets" {
  value = module.virtual_network.vnet_subnets
}

在状态文件中，输出如下所示：

"vnet_subnets": {
      "value": [
        "/subscriptions/<my_sub_id>/resourceGroups/rg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/GatewaySubnet",
        "/subscriptions/<my_sub_id/resourceGroups/rg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/VDMS",
        "/subscriptions/<my_sub_id/resourceGroups/rg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/external",
        "/subscriptions/<my_sub_id/resourceGroups/rg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/internal",
        "/subscriptions/<my_sub_id/resourceGroups/rg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/management"
      ],
      "type": [
        "tuple",
        [
          "string",
          "string",
          "string",
          "string",
          "string"
        ]
      ]
    }

我有一个虚拟机部署，我想使用vnet状态文件作为数据源，以便可以将VM分配给正确的子网。我的问题是，如何在vnet_subnets输出集中找到正确的子网？

对于您的需求，我认为您遇到的问题是，您无法从输出中找到要使用的特殊字符。

您可能会使用的可能方式是，将子网ID放入带有子网名称的映射中。然后，您可以使用名称专用的子网，并从地图中获取它。这是示例代码，您可以看一下：

variable "subnets" {
    type = list(string)
    default = [
        "test1",
        "test2",
        "test3"
    ]
}

variable "subnet_prefix" {
    type = list(string)
    default = [
        "10.0.1.0/24",
        "10.0.2.0/24",
        "10.0.3.0/24"
    ]
}


resource "azurerm_virtual_network" "example" {
  name                = "acceptanceTestVirtualNetwork1"
  address_space       = ["10.0.0.0/16"]
  location            = "East US"
  resource_group_name = "group_name"
}

resource "azurerm_subnet" "example" {
    count                                = length(var.subnets)
  name                 = element(var.subnets, count.index)
  resource_group_name  = "group_name"
  virtual_network_name = azurerm_virtual_network.example.name
  address_prefix       = element(var.subnet_prefix, count.index)
}

output "subnets_map" {
    value = zipmap(var.subnets, azurerm_subnet.example.*.id)
}

我看到您使用了这些模块，因此可以将vnet模块的输出作为VM模块的输入。
