Terraform 从未生成的资源应用地形

我正在尝试根据子网名称列表创建映射列表，因此我创建了以下内容：

创建了一个名为subnet_name的变量，类型为字符串列表

创建了空资源块以从此列表创建映射列表，如下所示：

如果我只执行这个块，我就有了正确的贴图列表，但是当我尝试将这个贴图列表与动态块一起使用时，这是不起作用的

resource "azurerm_virtual_network" "virtual_network" {
  address_space = "${var.cidr_network_range}"
  location = "${var.location}"
  name = "${var.virtual_network_resource_name}"
  resource_group_name = "${var.resource_group_name}"
  count = "${length(var.subnet_names)}"

  dynamic "subnet"{
    for_each = [for s in null_resource.subnet_mapping: {
      name = s.name
      prefix = cidrsubnet(element(var.cidr_network_range, 0),8 ,s.number)
    }]

    content {
      name = subnet.value.name
      address_prefix = subnet.value.prefix
    }
  }

  depends_on = [null_resource.subnet_mapping]
}

resource "null_resource" "subnet_mapping" {
  count = "${length(var.subnet_names)}"

  triggers = {
    name   = "${element(var.subnet_names, count.index)}"
    number = "${count.index}"
  }
}


resource "azurerm_resource_group" "virtual_network_group" {
  location = "${var.location}"
  name = "${var.resource_group_name}"
}

它应该是有效的，但是我仍然没有null_资源的输出，所以它失败了

dynamic "subnet"{
    for_each = [for s in null_resource.subnet_mapping: {
      name = s.name
      prefix = cidrsubnet(element(var.cidr_network_range, 0),8 ,s.number)
    }]

    content {
      name = subnet.value.name
      address_prefix = subnet.value.prefix
    }
  }

  depends_on = [null_resource.subnet_mapping]
}

我的错误消息：

  on main.tf line 10, in resource "azurerm_virtual_network" "virtual_network":
  10:       name = s.name

从消息中，我不清楚您要创建多少个VNET，因为您的代码有点混乱。对于

null\u资源的问题

，我认为这不是一个好的选择，我建议使用

locals

在这里，我假设您只想创建一个具有串行子网的Vnet，并使用列表存储子网的名称，然后使用下面的核心代码示例：

locals {
  subnets = [for sname in var.subnet_names: {
    name = sname
    # the index begin from 0, so you need to add 1
    number = index(var.subnet_names, sname) + 1
  }]
}

resource "azurerm_virtual_network" "virtual_network" {
  address_space = "${var.cidr_network_range}"
  location = "${var.location}"
  name = "${var.virtual_network_resource_name}"
  resource_group_name = "${var.resource_group_name}"


  dynamic "subnet"{
    for_each = [for s in local.subnets: {
      name = s.name
      prefix = cidrsubnet(var.cidr_network_range, 8 , s.number)
    }]

    content {
      name = subnet.value.name
      address_prefix = subnet.value.prefix
    }
  }
}

我这样解决了，我创建了一个名为

variable "subnets" {
  type = list(map(string))
  description = "A list of maps of names and network addresses bits for subnets that will be created inside this network (this is parallel to subnet_prefixes array)."
}

这样我已经创建了地图，我想已经自动创建了它，因为我以前张贴，但它似乎不是很常见的地形的方式

在Charles Xu示例中，映射将基于序列（1,2,3）创建，我希望始终以不同的方式使用它，如（21,24,26） 所以我能找到的唯一解决办法就是在之前强制地图

无论如何，谢谢大家

为什么不给点回应呢？你还想解决这个问题吗？或者你只想得到答案而什么也不做？不要忽视别人的帮助！我没有忽视，伙计，我想你的答案是我的。你应该接受我的回答。请检查我发布的代码，这是你的副本吗？我刚刚删除了空资源。

variable "subnets" {
  type = list(map(string))
  description = "A list of maps of names and network addresses bits for subnets that will be created inside this network (this is parallel to subnet_prefixes array)."
}

resource "azurerm_virtual_network" "virtual_network" {
  address_space = var.cidr_network_range
  location = var.location
  name = var.virtual_network_resource_name
  resource_group_name = var.resource_group_name

  dynamic "subnet"{
    for_each = [for subnet in var.subnets: {
      name = subnet.name
      prefix = cidrsubnet(element(var.cidr_network_range, 0),8 ,subnet.number)
    }]
    content {
      name = subnet.value.name
      address_prefix = subnet.value.prefix
    }
  }
}

resource "azurerm_resource_group" "virtual_network_group" {
  location = var.location
  name = var.resource_group_name
}
