Resources required on nodes for Test-DSCConfiguration #38

Closed anwather closed 7 years ago

anwather commented 7 years ago

When running test-dscconfiguration any resources required by the mof file must be on the remote nodes.

I have written a couple of functions to scan the mof, and copy required resources to the remote nodes before test-dscconfiguration has run.

Can you please review the changes at https://github.com/anwather/DSCEA. There is a new sample config file which needs the xSMBShare resource to be installed on the remote node. Note that the machine which runs Start-DSCEAScan also needs to have the resource as a source.

Thanks Anthony! It is unfortunate that currently Test-DSCConfiguration doesn't use the local DSC engine to look up a Resource Module location the way that Start-DSCConfiguration can (and automatically pull down missing resources at MOF integrity checking time).

Your code looks like something that would be a great contribution to the project. Have you tested it yet? One of the issues that we have with code within the scriptblock is that calling functions from our module inside of the scriptblock (i.e. code running within the runspaces) doesn't properly call other module functions. That's why we currently have the Repair-DSCEngine function defined within the script block at the moment.

Hey mate,

Yes tested with a single xResource, whole heap of other things to check I. E. Multiple resources. I do call my Copy-DscResource function while in the runspace and it worked, maybe cause I imported the module beforehand.

If you get a chance clone it and do a quick test but it works for me

I just tested it, works great! I had some minor issues with the fact that the Carbon module has a similarly named function to Copy-DSCResource' and I was getting parameter conflicts since that doesn't take a PSsession parameter, but once I cleared that up it worked great.
