Zipping your DSC Resources

When you are setting up a DSC Pull scenario, you will have to zip your DSC Resources in a correct format and by using proper tooling.

At first you need to zip your primary directory, and you have to give your zip file the correct naming. This should be Resourcename_versionnumber.zip (see screenshot below), and then placed in the “C:\Program Files\WindowsPowerShell\DscService\Modules directory”.PSDSC_Pull_Server

Please be aware that even though its ‘just a zip file’ not all programs zip the same way, if you for example use 7zip or winrar you could bump into eventid 4104: Failed to extract the module from zipfile.                                            PSDSC_notpropperlyzipped

If you however use the windows native compressing engine, everything will work out fine.PSDSC_zippedok

DSC Resource versioning fixed with WMF5 Production preview!

Last week I blogged about an issue with the DSC resource folder versioning in a DSC Pull scenario. DSC Resource folder versioning issue in a DSC-Pull scenario.

This week Microsoft released a new version of WMF 5.0  which fixes a whole range of issues.

While you still have to zip your DSC Resource without the version folder, the DSC engine now extracts the ZIP file to the corresponding folder version!

DSC Resource zip structure:

PSDSC_Pull_Server

DSC Resource client structure:

PSDSC_Pull_Client:

This means that now, we can use multiple versions of a DSC Resource on the same client. This will help when for example you only want to update 1 partial configuration on a server that uses a newer resource, while not having to update dependent others.
