Question

我有一个main.tf，variable.tf，可以使用源代码从名为vms.tf的/ module文件中对其进行引用 ../.

但是，如果我尝试构建多个VM，则第二个VM会不断抛出如下错误：错误：缺少必填参数

    on vms.tf line 6, in module "bar":
    6: module "bar" {

    The argument "client_id" is required, but no definition was found.

如果我仅构建一个虚拟机，则第一个虚拟机将运行良好，但是当我向模块中添加更多虚拟机时，它的行为就像没有凭据一样。除了环境变量，我尝试过将它们直接添加到提供程序下，没有骰子。

我的调用模块如下所示，它本身位于一个文件夹中：

        module "foo" {
            source   = "../."
            location = "westus"
            prefix   = "skachar"
        }
        module "bar" {
            source   = "../."
            prefix   = "skachar2"
            location = "eastus"
        }

我根据注释部分中某人的要求添加了以下代码。它是我的main.tf文件，位于我的模块所在的文件夹下。我也将添加我的variable.tf文件，只是为了更全面。它将位于main.tf文件下面，该文件是您在本段下面看到的代码。我真的很想知道为什么第二台VM炸毁了。我为其提供了一个唯一的前缀，并且错误消息毫无意义。如果没有凭据，则不会配置第一个VM。任何人，如果有人可以指出我正确的方向，也许我在某处缺少一些文档。感谢您提供的任何帮助。

仅供参考-我运行的是单个VM的构建，并且构建起来没有问题。...我必须提供正确的密码，但其他所有操作都顺利进行。再次感谢任何人都可以提供的帮助。干杯， -山姆

感谢您提出的使用count循环创建多个资源的建议，我对count很熟悉，它很有用...

但是，正如我在最初的帖子中所说的那样，我收到一条有关信用凭证的错误消息。我已经解决了这个问题。我发现通过将VS Code从PowerShell更改为PowerShell Integrated Console，可以在其中加载env变量，从而使您可以使用我发布的模块。不知道为什么第一个下拉列表不适用于多种资源。

如果有人在设置环境变量时确定在VS Code终端下拉列表中选择了第二个PowerShell环境，应该碰到这个问题。包括一个片段，以澄清我在说什么。 PowerShell Integrated Console 干杯， -山姆
