Powershell DSC：參數不起作用的複合資源

Question

我正在使用DSC複合資源，但似乎無法使其工作。我的代碼：

E：\開發\ DSCResources \ run.ps1：

Import-Module Test -Force 

Configuration Run 
{ 
    Import-DscResource -ModuleName Test 

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

Run 

和複合資源：

E：\開發\ DSCResources \測試\ test.schema。 PSM1：

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

    Log Example { 
     Message = $Teststring 
    } 
} 

E：\開發\ DSCResources \測試\ test.psd1：

#

@{ 

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

# Version number of this module. 
ModuleVersion = '1.0'

GUID = 'a0c8ed64-00bc-4112-997f-d65d567bc043'

# Modules that must be imported into the global environment prior to importing this module

# FormatsToProcess = @() 

# Modules to import as nested modules of the module specified in RootModule/ModuleToProcess 
# NestedModules = @("") 

# Functions to export from this module 
#FunctionsToExport = '*' 

# Cmdlets to export from this module 
#CmdletsToExport = '*' 

# Variables to export from this module 
#VariablesToExport = '*' 

# Aliases to export from this module 
#AliasesToExport = '*' 

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

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

# Private data to pass to the module specified in RootModule/ModuleToProcess 
# PrivateData = '' 

# HelpInfo URI of this module 
# HelpInfoURI = '' 

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

} 

但參數沒有得到供應，而我得到下面的輸出：

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

所以它看起來像複合資源的工作，但傳遞的參數不讀。所以它保釋出來並要求我手動輸入參數。

合成資源是否被破壞？或者我做錯了什麼？

更新後，我可以成功地重現您的問題，之後我無法再次使我的原始配置工作，使我相信我在我的原始測試中犯了一些錯誤。在以下示例中，我將使用BaseConfig作爲配置名稱，MyParameter作爲參數名稱。

爲了創建具有行由行指令較長的描述，我寫了一篇博客上的主題：http://robertwesterlund.net/post/2014/03/12/creating-a-composite-dsc-configuration-with-parameters

參數的複合配置是一個普通的模塊

當複合配置是作爲普通模塊創建的（例如直接在C:\Program Files\WindowsPowerShell\Modules\MyModuleName中），它看起來像一個普通的Cmdlet。這意味着，將參數傳遞到複合配置我不得不這樣做：

Import-DscResource -ModuleName BaseConfig 

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

我必須承認，預期爲其他地區的DSC資源，我不知道這是否會表現。

的複合配置，支持參數

我想寫的配置方式是以下幾點：

Import-DscResource -Name BaseConfig 

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

（請注意，Import-DscResource也不同。）

得到這個工作，我必須製作一個虛擬容器模塊（當然，如果需要，它可以包含實現，但我只創建了一個空的psm1文件和一個指向該psm1文件的psd1文件即在沒有實現容器模塊之後，我爲複合配置製作了DSC資源模塊（位於MyContainerModule\DSCResources\MyCompositeConfiguration文件夾中）。在此之後，它就像預期的那樣工作。這可能是創建組合配置的正確方法。
