Power Shell Task execution on Windows Instance

Automation/IaC
1

Hello Experts,

I provisioned the below Windows Instance Type (Morpheus Image) in Azure Public Cloud. Then Morpheus created a user that was defined under the user profile and I was able to access RDP with that user.

I tried to execute powershell task on that instance to install IIS which used the Get-WindowsFeature cmdlet and Install-WindowsFeature cmdlet. From Morpheus portal, it says not recognized those cmdlet. I was able to use those cmdlets by using the RDP console with that username.

When I check powershell execution user from Morpheus with “whoami powershell command” it shows nt authority\system . is that reason we can’t use those cmdlets from Morpheus? or How we can do that?

And I also noticed, Morpheus defined the AzureAdmin username in the Server RPC setting. I am still not able to install IIS even though I changed the username and password in the RPC setting.

It will be great if you can suggest.

Thanks,

If you are seeing ntauthority\system, the script is/should be executing over the Morpheus Agent. I would have to see how your task is configured to further analyze.

Please also take a look at this RDS installation. The steps would be very similar to installing IIS.

Thanks for sharing Chris.

I created automation task with the command “Install-WindowsFeature -Name Web-Server -IncludeManagementTools” with resource target type and enable elevated shell.

So, I just provisioned another instance (same image) and kept the default settings of Server, RPC username is AzureAdmin and Morpheus defined the password automatically. And I executed the automation task at server level (not instance level), execution was successful, and the IIS service was installed. The PowerShell execution user was AzureAdmin.

I don’t know why the agent method was used at the instance level of execution, even though I didn’t install agent due to the Morpheus portal being inaccessible from the Azure cloud.

Thanks,
Aung

Hi Aung,

you can create a shell task and run the below script
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command {get-windowsfeature}

Alternately you can also create a PowerShell script template and run get-windowsfeature -name web-server

Thanks
