Ensure-DSC and Module version

[philippe.camelio_3885]

Hello

As PS Module version management is a mess, I am looking to call Ensure-DSC with a specific version of a module as it is possible with the Invoke-DscResource unsuccessfully.
Any exemple might helpfull

Thanks in advance

Best Regards

PhilippeC.

Hmmm, I'm not sure if it's possible... I don't know if PowerShell even allows multiple versions of the same module/resource to be installed on the same server?

The Invoke-DscRessource allows this.
Ensure-DSC should be improved, if possible. It's been a long time since Otter was updated

Invoke-DscResource -Method Test -Name WindowsFeature -Property @{Name='RSAT-AD-PowerShell'; IncludeAllSubFeature=$true; ensure='Present'} -ModuleName @{ModuleName=’PSDscResources’; ModuleVersion=2.2.0.0’} -Verbose

As enhancement, it would be nice to have a function Ensure-Module in order to manage properly PS Module.

I have done a small set of functions based on PackageManagement but it does not work properly for the Module installation as it does remove the old version.

##AH:UseTextMode
##AH:Description Définition d'un dépôt
module PackageManagementSource<$Nom, $Ensure = present, $SourceLocation, $ProviderName = PowerShellGet, $InstallationPolicy = Untrusted>
{
    Ensure-DscResource
    (
        ConfigurationKey: Name,
        Name: PackageManagementSource,
        Module: PackageManagement,
        Properties: %(Name:$Nom,ProviderName:$ProviderName,SourceLocation:$SourceLocation,InstallationPolicy:$InstallationPolicy,Ensure:$Ensure)
    )
}

##AH:UseTextMode
##AH:Description Installation de modules PS à partir d'un dépôt
module PackageManagement<$Module, $Version, $Source = internal-psm, $Ensure = Present>
{
    log-information Module: $Module - $Version - $Ensure;
    Ensure-DscResource
    (
        ConfigurationKey: Name,
        Name: PackageManagement,
        Module: PackageManagement,
        Properties: %(Name:$Module,RequiredVersion:$Version,Source:$Source,Ensure:$Ensure)
    );
}

note:
There are some prerequisites to have PackageManagement 1.4.7.

Hi @philippe-camelio_3885,

For an Ensure-PSModule command, here is what I'm thinking.

Ensure-PSModule {
   ModuleName: ...
   Version: ...
   MinVersion:...
   MaxVersion:...
   Force: false
   AllowClobber: false
   Repository: ... 
   Credential: ...(I expect this to be a ResourceCredential)
   Scope:...
   Properties: ... (any other additional properties to pass to Install-Module)
}

Where it just ensures that version (or within the min/max) is installed.

Am I understanding your request correctly?

Thanks,
Rich

Hi @rhessinger
Sorry for the delay

Yes this is exactly what it should be.

Hi Phillipe,

I created an issue on GitHub, #8, to track adding this to the extension. I'll reply back once there is a CI version released of the extension.

Thanks,
Rich
