复合配置的参数是普通模块

Question

我正在研究DSC复合资源，但我似乎无法让它工作。我的代码：

E：\开发\ DSCResources \ run.ps1：

Import-Module Test -Force

Configuration Run
{
    Import-DscResource -ModuleName Test

    Node localhost 
    {
        Test Common {
            TestString = "blabla"
        }
    }
}

Run

复合资源：

E：\开发\ DSCResources \测试\ test.schema.psm1：

Configuration Test {
    Param (
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [string]$Teststring
    )

    Log Example {
        Message = $Teststring
    }
}

E：\开发\ DSCResources \测试\ test.psd1：

#
# Module manifest for module 'test'
#
# Generated by: Administrator
#
# Generated on: 3/12/2014

@{

# Script module or binary module file associated with this manifest.
RootModule = 'test.schema.psm1'

# Version number of this module.

# PrivateData = ''

# HelpInfo URI of this module
# HelpInfoURI = ''

# Default prefix for commands exported from this module. Override the default prefix using Import-Module -Prefix.
# DefaultCommandPrefix = ''

}

但是没有提供参数，我得到以下输出：

cmdlet Test at command pipeline position 1
Supply values for the following parameters:
Teststring:

因此，似乎复合资源确实有效，但是不会读取传递的参数。所以它挽救了并要求我手动输入参数。

复合资源是否已损坏？或者我做错了什么？

更新后，我可以成功重现您的问题，之后我无法重新启动原始配置，让我相信我在原始测试中犯了一些错误。在以下示例中，我将使用BaseConfig作为配置名称，使用MyParameter作为参数名称。

为了使用逐行说明创建更长的描述，我写了一篇关于这个主题的博客文章：http://robertwesterlund.net/post/2014/03/12/creating-a-composite-dsc-configuration-with-parameters

复合配置的参数是普通模块

当复合配置创建为普通模块时（例如，直接在C:\Program Files\WindowsPowerShell\Modules\MyModuleName中），它看起来像普通的Cmdlet。这意味着，要将参数传递给我必须执行的复合配置：

Import-DscResource -ModuleName BaseConfig 

Node localhost 
{ 
    BaseConfig Common -MyParameter "My Parameter Value" 
    { 
    } 
}

我必须承认，我不知道这是否会像其他部分的DSC资源一样。

支持参数

的复合配置

我想编写配置的方式如下：

Import-DscResource -Name BaseConfig 

Node localhost 
{ 
    BaseConfig Common 
    { 
        MyParameter = "My Parameter Value" 
    } 
}

（请注意，Import-DscResource也有所不同。）

为了使这个工作，我必须创建一个虚容器模块（当然，如果需要，它可以包含实现，但我只创建了一个空的psm1文件和一个psd1文件指向那个psm1文件。在没有实现容器模块的情况下，然后我为复合配置创建了一个DSC资源模块（位于MyContainerModule\DSCResources\MyCompositeConfiguration文件夹中）。之后它按预期工作。这可能是正确的方法创建复合配置。
