Unable to invoke DSC resources

[vinithmenon28]

Hello I am trying to use the nxComputerManagement DSC resource, i have a win2k12r2 machine which has WMF 5.0 installed, when i try to test it out below i get the below error.

Configuration MyDSCDemo {

I have the PSDSC for linux installed from https://www.microsoft.com/en-us/download/details.aspx?id=49150

Did you install the networking/computer management modules on the Linux computer?

[vinithmenon28]

no I did not , can you guide me how to do that. I did not find any step by step guide for v1.1

[KrisBash]

Documentation is here: https://msdn.microsoft.com/en-us/powershell/dsc/lnxgettingstarted and in the release notes .pdf. I'm planning to get docs up to date on GitHub though.

InstallModule.py Installs a custom DSC resource module. Requires the path to a .zip file containing the module shared object library and schema MOF files.

# sudo ./InstallModule.py /tmp/cnx_Resource.zip

The path is /opt/microsoft/dsc/Scripts

[vinithmenon28]

I installed the rpm package for DSC and also the latest OMI package but still i get this error

below are the snippets of the commands i ran, i have not posted all the commands but the imp ones.

[root@CENTOSTESTDSC1 Scripts]# wget https://github.com/Microsoft/PowerShell-DSC-for-Linux/releases/download/v1.0.0-466/PSDSC.tar.gz [root@CENTOSTESTDSC1 Scripts]# wget https://collaboration.opengroup.org/omi/documents/33715/omi-1.0.8.tar.gz

[root@CENTOSTESTDSC1 Scripts]# sudo rpm -Uvh omi-1.0.8.ssl_100.x64.rpm

[root@CENTOSTESTDSC1 Scripts]# sudo rpm -Uvh dsc-1.1.0-466.ssl_098.x64.rpm

When i tried to install the modules i got the below error

Below are the set of commands i punched in at the Linux console ( cent OS) to configure DSC

It would be great if you can publish a step byb step document with screen captures on how to configure DSC v1.1 for linux for people who come from non-linux backgrounds.

[JumpingYang001]

You can try "yum install unzip", I guess you didn't install unzip to extract the zip file.

[vinithmenon28]

its already installed

[root@CENTOSTESTDSC1 Scripts]# yum install unzip Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile Package unzip-6.0-2.el6_6.x86_64 already installed and latest version Nothing to do [root@CENTOSTESTDSC1 Scripts]#

[vinithmenon28]

also note i installed the below rpm packages

[root@CENTOSTESTDSC1 Scripts]# sudo rpm -Uvh omi-1.0.8.ssl_100.x64.rpm [root@CENTOSTESTDSC1 Scripts]# sudo rpm -Uvh dsc-1.1.0-466.ssl_100.x64.rpm

Why did you do the steps below: After installing omi and dsc packages, you can install the module directly if unzip were already installed on your machine: /opt/microsoft/dsc/Scripts/InstallModule.py nxComputerManagement_1.0.zip

[vinithmenon28]

Hi Ting Liu, i revered back to my snaphot and ran the below steps, i configured omi, copied over all the packagaes and modules using winscp.

i did not do the wget for PSDSC.tar.gz as you suggested, but after this when i run the DSC configuration i get the below error.

Also i did not see the DSC folder here after only installing the rpm package

[vinithmenon28]

the resources i downloaded from https://www.microsoft.com/en-us/download/details.aspx?id=49150

here's the screenshot when i run DSC config when i installed the modules from above location

[vinithmenon28]

also i cant find anything related to error from

[root@CENTOSTESTDSC1 log]# cat omiserver.log [root@CENTOSTESTDSC1 log]# cat dsc.log

[KrisBash]

There are multiple issues going on here, let's try to address them one by one. 1) Firstly, it appears that you installed the packages (omi and dsc rpms), and then built OMI from source. This is redundant and results in two instances of OMI, one at /opt/omi and one at /opt/omi-1.0.8. The installation of DSC from rpm will use the /opt/omi/ directory. So for logs, you should look at /var/opt/omi/log for dsc.log and omiserver.log 2) You are getting errors in the nxService resource, which is a built-in resource. This implies something wrong with the configuration. Can you provide the configuration (.ps1 or .mof) for this instance? 3) The module issue looks like a bug in the packaging of the .zip. My sincere apologies for that. Here's a workaround until we post the fix.

unzip nxComputerManagement_1.0.zip
cd nxComputerManagement_1.0
zip -r nxComputerManagement_1.0.zip nxComputerManagement/*
cp nxComputerManagement_1.0.zip /tmp/
sudo /opt/microsoft/dsc/Scripts/installModule.py /tmp/nxComputerManagement_1.0.zip 

unzip nxNetworking_1.0.zip
cd nxNetworking_1.0
zip -r nxNetworking_1.0.zip nxNetworking/*
cp nxNetworking_1.0.zip /tmp/
sudo /opt/microsoft/dsc/Scripts/installModule.py /tmp/nxNetworking_1.0.zip

We'll get the fixed module uploaded to the PS Gallery asap. We're working on an updated release of the DSC package that will also include the module pacakging fix.

[vinithmenon28]

Thanks for the help Kris, yes i was able to install the nxNetworking module using the steps you gave above but for nxComputerManagement it failed.

I got the module zip files from https://www.microsoft.com/en-us/download/details.aspx?id=49150, after i installed the msi package i was able to see the modules here and i copied them over to the cenntos vm using winscp

Also i saw a number of versions of RPM packages when i installed the above msi package. i saw a 098 an 100 version. how can we identify which we need to install?

Here are the screencaptures for the module installation.

As you can see above when i try to install nxComputerManagement via Install.py it results in an error, module files not found but for nxNetworking it worked.

Also here's my mof file.

Also Kris, it would be great if you could update / publish a new blog on a step by step series for PSDSCLinux v 1.1, just like what you had done for v 1.0 http://blogs.technet.com/b/privatecloud/archive/2014/05/19/powershell-dsc-for-linux-step-by-step.aspx

It would be helpful for non-linux guys to easily follow your guide

[vinithmenon28]

Hey Kris, just an update, finally it got fixed, i did a rm-rf of the nxComputerManagement module and it deleted all the files, then i again did a re-copy using winscp and voila!! it finally worked.

Thanks a lot guys for your excellent support :), lets roll out DSC Linux in production :+1:
