这里是新的地形学习者，尝试通过示例和编码进行学习。我在寻找可以创建虚拟机的地形模块，在这里找到了这个例子https://faun.pub/creating-a-windows-vm-in-azure-using-terraform-which-way-is-best-13aff3ed9b74我认为这将使我的地形基础知识更上一层楼，因为创建虚拟机是我熟悉的过程，可以在此基础上进行构建。这次经历令人沮丧。这是我的第三周了，感觉还是好几英里之外。
我读了第一个解决方案，我的文件的结构与描述的完全相同。注意，我试过第一种方法，但错误百出，所以我决定尝试第二种方法，它应该更简单。
我创建了一个名为simple_vm的文件夹，在里面还有另一个文件夹vm。
内容如下。
vm_module_local_example.tf
# Create an Azure VM cluster with Terraform calling a Module. Creates 1 for Windows 10 desktop and 1 for Windows 2019 Server.

vm_subnet_id = module.network.vnet_subnets[0]
vm_name = "tfdtlocmod"
vm_size = var.desktop_vm_size
publisher = var.desktop_vm_image_publisher
offer = var.desktop_vm_image_offer
sku = var.desktop_vm_image_sku
static_ip_address = "10.0.1.15"
activity_tag = "Windows Desktop"
admin_password = module.vmpassword.secretvalue
}
module windows_server_vm_using_local_module {
source = "./vm"
resource_group_name = azurerm_resource_group.rg.name
location = "uksouth"
sloc = "uks"
vm_subnet_id = module.network.vnet_subnets[1]
vm_name = "tfsvlocmod"

sku = var.server_vm_image_sku
static_ip_address = "10.0.2.15"
activity_tag = "Windows Server"
admin_password = module.vmpassword.secretvalue

我可以看到很多错误都和未声明的变量有关。然后我创建一个变量文件如下(不在vm文件夹中(。
variable "subscription_id" {
}
variable "client_id" {
}
variable "client_secret" {
}
variable "tenant_id" {

variable "global_settings" {

}
variable "server_vm_image_offer" {
}
variable "server_vm_image_sku" {
}
variable "server_vm_image_version" {
}
variable "server_vm_size" {

创建了一个名为terraform.auto.tfvars.的文件

server_vm_image_offer = "WindowsServer"
server_vm_image_sku = "2019-Datacenter"

现在，我在网上的例子中似乎非常不走运，在上面的例子中有很多缺失的变量，作者没有指定是否应该使用不同例子中的某些文件(链接上有很多代码显然是为了实现相同目标而使用的不同技术(。同时，我对此并不熟悉，不确定是否真的可以说发布的解决方案中缺少文件/详细信息。我没有幸联系到作者，也没有github repo来检查我是否有正确的设置，因此我在这里寻求帮助。我想做的就是提高我对地形模块的知识，我更喜欢有解释和例子，这样我也可以练习。我可以看看git-reos，但这只会给我解决方案，而没有解释或学习机会。
正如评论中的人所提到的，看起来你在遵循一个不完整或过时的教程。我想，如果我解释一下如何理解产生的错误，这样你将来就可以克服这个障碍，这可能会对你有所帮助。

在上面的消息中Terraform说"；在文件vm_module_local_example.tf的第4行，您已经将resource_group_name设置为azurerm_resource_group.rg.name的值，但当我尝试查找资源"时；azure_resource_group"；其名称为"；rg"；我什么也找不到。要修复它，你需要编码一个资源，比如：
resource "azurerm_resource_group" "rg" {
name = "example"
location = "West Europe"
}
一旦完成，则第4行将把CCD_；例如"；。

这是一个很好的例子，在名为vm_module_local_example.tf的文件的第7行，有一个对module.network.vnet_subnets[0]的调用。因此Terraform将在继续操作之前查找一个名为network的模块。你需要这样的代码：
module "network" {
# pass in whatever the module needs...
}
根据错误，模块似乎应该包含一个名为vnet_subnets的资源，该资源是用count生成的，因为它依赖于一个基于零的索引(这是[0]部分(。
无论如何，希望这能有所帮助！
