Azure Automation State Configuration
Azure Automation State Configuration (previously Azure Automation DSC), is a service provided by Azure that allows you to write, manage and compile PowerShell Desired State Configuration (DSC) configurations and assign these configurations to target virtual machines (or any server or workstation to be honest). On its own, State Configuration provides some basic configuration examples, but its true power comes form the ability for you to define your own configurations.
User created configurations need to be imported and compiled before the configuration is applied to a virtual machine. It is common when creating DSC configurations to rely on a variety of DSC Resources. The modules containing these resources need to be imported into Azure Automation for it to be able to compile any configuration. So how do we import and update these modules?
The first mechanism to manage the PowerShell modules is through the Azure Portal, by going to your Automation Account > Shared Resources > Modules. Here you can add modules from a zip file, update the built in Azure modules, or add modules from the PowerShell Gallery. This provides a simple mechanism particularly if you are starting; unfortunately, most production configurations will need multiple modules, making the Azure Portal difficult to use.
We can also manage modules via ARM templates. Define the template is relatively straight forward but requires a couple of tricks to get started. I will put together a separate blog post on how you can define your own ARM template.
I wanted to help those starting out with State configuration. My goal was to help accelerate new State Configuration deployments, by creating a “starter” ARM template that would install the most common PowerShell DSC modules that are in the PowerShell Gallery and the most common in my production DSC configurations. This ARM template could also be used to ensure that the modules are also updated on a regular basis.
So what modules are included? I selected 32 modules in the end. These cover the configuration of core Windows, Windows Server roles and features, security hardening, package management and Chocolatey. Most of the modules are maintained by Microsoft, however four modules, cChoco, cSpeculationControlFixes, UpdateServicesDSC and xSystemSecurity that are maintain by members of the community.
