PowerShell DSC Active Directory configuration

[Michal Machniak (mimachniak)]

Dear Team,

Question is there any guide or some example how to move DSC 2.0 to DSC 3.0, do we need to create custom resource / adapter ?

`powershell

Configuration ADDS_Setup {
Import-DscResource -ModuleName ActiveDirectoryDsc

Node "MyDC" {
    # Install AD DS Role
    WindowsFeature ADDSInstall {
        Name   = "AD-Domain-Services"
        Ensure = "Present"
    }

    # Create a new AD Forest
    ADDomain NewDomain {
        DomainName                    = "contoso.com"
        DomainAdministratorCredential = Get-Credential
        SafemodeAdministratorPassword = Get-Credential
        DatabasePath                  = "C:\NTDS"
        LogPath                       = "C:\NTDS"
        SysvolPath                    = "C:\SYSVOL"
        DependsOn                     = "[WindowsFeature]ADDSInstall"
    }

    # Ensure DNS is configured properly
    DNSServerAddress SetDNS {
        Address    = "127.0.0.1"
        InterfaceAlias = "Ethernet"
        DependsOn = "[ADDomain]NewDomain"
    }
}

}

Generate MOF File

ADDS_Setup -OutputPath "C:\DSC"

Apply Configuration

Start-DscConfiguration -Path "C:\DSC" -Wait -Verbose -Force

So, basically, the same question was raised during the latest DSC community call last Wednesday, and I think Chris Hill is also referring to it in #529.

There isn't currently a direct guide on how to migrate. Nonetheless, for the indirect answer, I would refer to the great discussion Chris, Steve, and Jason had during this community call (which will hopefully be up soon on https://www.youtube.com/@dsccommunity2958). For a more direct answer, either you would:

• Create your configuration document using .json or .yml and point towards the relevant adapter for the resource in your v2 document
• There is a best effort command in the PSDSC, which some of the logic I borrowed from the functions already available around the community.

Don't confuse this module with the PSDesiredStateConfiguration module. It's also good to point out that DSC currently doesn't have an LCM, meaning the Node part isn't really relevant in this context.
