PowerShell DSC:参数不起作用的复合资源

Question

我正在研究DSC复合资源，但我似乎无法正常工作。我的代码：

e： dev dscresources run.ps1：

Import-Module Test -Force
Configuration Run
{
    Import-DscResource -ModuleName Test
    Node localhost 
    {
        Test Common {
            TestString = "blabla"
        }
    }
}
Run

和复合资源：

e： dev dscresources test test.schema.psm1：

Configuration Test {
    Param (
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [string]$Teststring
    )
    Log Example {
        Message = $Teststring
    }
}

e： dev dscresources test test 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.
ModuleVersion = '1.0'

#AliasesToExport = '*'

# ModuleList = @()
# List of all files packaged with this module
# FileList = @()

# PrivateData = ''
# HelpInfo URI of this module
# HelpInfoURI = ''
# Default prefix for commands exported from this module. Override the default prefix using Import-Module -Prefix.
# DefaultCommandPrefix = ''
}

但没有提供参数，我将获得以下输出：

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

因此，复合资源似乎确实有效，但是传递的参数未读取。因此，它可以保释并要求我手动输入参数。

复合资源是否损坏？还是我做错了什么？

您更新后，我可以成功地重现您的问题，此后我无法再次使我的原始配置再次工作，这让我相信我在原始测试中遇到了某种错误。在以下示例中，我将使用BaseConfig进行配置名称，而MyParameter用于参数名称。

为了创建一个逐行说明的更长描述，我写了一篇博客文章：http：//robertwesterlund.net/post/post/2014/03/03/12/creating-a-compomposite-dsc - 配置与参数

参数是一个普通模块的复合配置

当创建复合配置作为普通模块（例如，直接在C:Program FilesWindowsPowerShellModulesMyModuleName中）时，它似乎的行为就像普通的CMDLET。这意味着，要将参数传递到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资源那样行事。

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。）

要使此工作工作，我必须制作一个虚拟容器模块（当然可以在必要时包含实现，但我只创建一个空的psm1文件和一个指向该PSM1文件的psd1文件。制作容器后。然后，我没有实施的模块，然后为复合配置制作了一个DSC资源模块（位于MyContainerModuleDSCResourcesMyCompositeConfiguration文件夹中）。此之后，它正如预期的。这可能是创建复合配置的正确方法。
