Simple DSC Example

One thing I am doing to get more practice with Desired State Configuration is to create configurations for existing servers. I am grabbing the easiest things to script and working out from there. Here one I quickly put together for our terminal server boxes.

$ConfigData = @{
    AllNodes = @(
        @{
            NodeName = "*"
        },
        @{
            NodeName = "ProdServer1";
            
            Database = "database";
            DatabaseServer = "DBServer"
        },
        @{
            NodeName = "ProdServer2";
            
            Database = "database"
            DatabaseServer = "DBServer"
        },
        @{
            NodeName = "QAServer1";
            
            Database = "QAdatabase"
            DatabaseServer = "DBServer"
        }
    )
}


Configuration TerminalServer
{
   node $allnodes.NodeName {
        WindowsFeature Backup {
            Name = "Windows-Server-Backup";
       }
   }

   node $allnodes.NodeName
   {
   
   

       WindowsFeature DesktopExperience {
        Name = "Desktop-Experience";
        IncludeAllSubFeature = "True";
       } 

       WindowsFeature RDS {
        Name = "RDS-RD-Server";
        IncludeAllSubFeature = "True";
       }         
   
       
       Registry ProductdDatabase{
        Key = "HKLM:\SOFTWARE\company\product";
        ValueName = 'InitialCatalog';
        ValueData = $node.Database
       }

       Registry ProductDatabaseServer{
        Key = "HKLM:\SOFTWARE\company\product";
        ValueName = 'DataSource';
        ValueData = $node.DatabaseServer
       }

   }
} 

TerminalServer -ConfigurationData $ConfigData
