Creating a PowerShell DSC extension for your custom tasks

Following my post on automating your mundane Azure Virtual Machine Windows provisioning tasks with PowerShell DSC, it may happen that you have custom tasks that you want to do that that are not already available on PowerShell gallery. You may also have custom complex logic that you want to reuse across many different DSC scripts that you would like to centralize. This is where extensions come into play. It allows you to create custom resource operations that you can use within your nodes provisioning. There are a few ways to create extensions: Using MOF-based resources in PowerShell Using Class-based resources in PowerShell Using Composite resources in PowerShell Using MOF-based resources in C# Using the Resource Designer Tool Today, I will…

SSL certificates management using Lets Encrypt, Azure Automation and Web Apps

I’ve been doing a lot of automation lately in regards to SSL certificates and Lets Encrypt.

Finding the SKUs of Azure VMs images with Powershell

I always struggle to know what to put in the imageReference node of the storageProfile node for an Azure VM when I want to automate the creation process through ARM (Azure Resource Manager) templates. We can find all of those using the Azure PowerShell modules. Below is a small script to automate the creation of the imageReference node where you can find and filter through the different location, publishers, offers and skus to get what you need.

$location = Get-AzLocation | select displayname | Out-GridView -PassThru -Title "Choose a location"
$publisher = Get-AzVMImagePublisher -Location $location.DisplayName | Out-GridView -PassThru -Title "Choose a publisher"
$offer = Get-AzVMImageOffer -Location $location.DisplayName -PublisherName $publisher.PublisherName | Out-GridView -PassThru -Title "Choose an offer"
$title = "VM SKUs for {0} {1} {2}" -f $location.DisplayName, $publisher.PublisherName, $offer.Offer
$sku = Get-AzVMImageSku -Location $location.DisplayName -PublisherName $publisher.PublisherName -Offer $offer.Offer | select SKUS | Out-GridView -Title $title -PassThru
$imageReference = @{ publisher = $publisher.PublisherName; offer = $offer.Offer; sku = $sku.Skus; version = "latest" }
$imageReference | ConvertTo-Json -Depth 4
