PowerShell DSC Journey – Day 22

Alright, after my little fiasco yesterday I need to do a little re-configuring of my Configuration because of course DSC will not allow a Plain text password.

Here is the new version of the Configuration.

Now, let’s try to run this and see what breaks. And. Nothing breaks. I am literally speechless. Seriously.

Well. Here goes nothing. And I forgot to change something back in .psm1 file when I was messing around with it yesterday that caused this entire thing to blow up. I will spare you all the red text but here is the error.

With that fixed I try to run it, and I don’t get any errors, but clearly I have something to fix with my Test-TargetResource function because it just skipped running Set-TargetResource.

So, let’s see if we can figure out what’s going on. I am pretty sure this section is the problem.

I set the $result to $false, then tested for the $VMMServer, and returned $True, so DSC was like “oh hey, everything is gravy.” Fail on my part. Let’s fix this. I already know if the Credential or VMMServer is invalid that it will fail, so I just need to check to make sure $ResourceVMMServer exists and then do the rest of my checks. I am pretty sure this is going to fail for a couple of reasons, but I am going to test this anyways in the interest of full disclosure :).

I run several of my tests that I expect to return both $True and $False. I made a few changes and added one line, so here is the new and improved section of my code.

So, let’s try this again! HOLY BUCKETS IT WORKED! Minus, one small issue.


Now, the one issue there is that no VMNetwork was set. Probably because there is no network adapter, which I am guessing I forgot to include in my Set-TargetResource. Let’s take a look.

Yeah, that’s not going to work. I need to create the adapter first. Turns out it’s easier than I thought it would be. Just kidding, I can’t use the parameter for $VMNetwork, it needs to be a different type.

Which opens a whole new can of worms because I need to check to make sure that is a valid VM Network somewhere. For the purposes of this, I am going to assume that if it should be present, it is a valid name. Actually I lied. We aren’t going to do that, because that opens up a giant mess when it comes to creating a new Virtual Network.

After banging away on this for about the last 30 minutes I am going to stop here for the day and pick it up again tomorrow. I am currently stuck on getting the right object type from Get-SCVMNetwork to pass to……..oh hell…wait a minute. Just kidding! Kidding again. I have a moment of genius! And this is also where I hate Virtual Machine Manager anymore. Only thing good to say is that I learned a hell of a lot more than I ever wanted to know about VMM cmdlets this afternoon.

So, let me delete the Hardware Profile and run my Configuration again. The network adapter didn’t get created. My brain is exhausted. I’m done for today. For real this time.
