PowerShell DSC - using an IP address to Configure a Workgroup Machine


PowerShell’s Desired State Configuration is becoming a core component of Windows and is included with the installation of PowerShell 5.

Earlier I wrote about enabling WinRM using a self-signed certificate (   Use those instructions to configure WinRM on a newly built machine.

Using Azure Automation with only REST API’s

Azure Automation is the next step in Microsoft’s Orchestration path.  Using predefined workflows / with REST/Odata/WebAPI has been a core component of Orchestrator, Service Management Automation and the Cloud based Azure Automation.

Hardware Reporting with PowerShell

WMI is easy to use and great for querying information about remote machines.  It’s the obvious choice for reporting on hardware usage – especially for scoping EC2 instances.  What is a little more interesting is using the retrieved information to construct a report.

AWS EC2 - Domain Join RHEL7

This example shows how to join a RedHat 7 EC2 instance to an Active Directory Domain.

Enabling Windows Remote Management (WinRM) with HTTPS

Windows Remote Management is a core technology for the remote management and configuration of Windows machines.  WinRM is essential for automating complex Azure and AWS tasks.  This guide will outline how to establish WinRM using SSH and a self-signed certificate.  A certificate issued from a Certificate Authority would be preferable but for the purpose of establishing a test environment, the steps below are enough to get the technology working.

This demonstration is in three parts.

Invoking Lambda through the AWS API Gateway with PowerShell

The ability to invoke Lamda functions via REST based web API is incredibly powerful.  As the API gateway is relatively new functionality, the documentation surrounding REST requests and PowerShell is sparse with official documentation sometimes confusing and appearing to be contradictory.

The attached PowerShell routine can be used to make signed GET and POST requests to an API advertised Lambda script.

Calling PowerShell Modules with the REST / ODATA IIS Server extension (Example 2 - SSH)

To demonstrate how powerful the IIS Odata extension for PowerShell is, I’ve tweaked the SSH PowerShell module that I published previously for use with Azure Pack.  By doing so, as long as I can connect to my Windows IIS web server, I can relay SSH commands from any other physical environment.

You will need to have setup the Odata IIS server extension as described in

Calling PowerShell Modules with REST / ODATA API

For a long time now, Windows Server has come with a feature called the “Management OData IIS Server Extension”.  As technology increasingly moves toward cloud computing and Microsoft technology is congealing around PowerShell, the power of this little known feature could hardly be overstated.  Built-in to Windows is the ability to run any PowerShell module remotely via a REST / ODATA API call. 

SMA Modules: Extracted Activity Data "Empty" or Missing

Service Management Automation is young enough to have a number of quirks that can be frustrating to get around.  One surprising quirk has been with SMA Module Activity Data (i.e. functions) to not appear on all machines consistently.
