AVD Host Pool Deployment

This solution was designed to provide a quick start for using Infrastructure as Code for AVD. It's a simple solution that combines a Custom UI Definition and ARM template to deploy a Host Pool, Add Session Hosts, and executes a Post Deployment Script.

Additionally the solution was written in BICEP to provide an ease of use and mechanism for customizations. To get started you will need the following:

• Azure Storage Account with a Blob Container housing your PowerShell script (Use provided PostConfig.ps1 as an example)
• VS Code for customizing the User Interface and/or code for deployment

Currently it provides a way to deploy a Host Pool with diagnostics enabled, using a KeyVault as an option for domain and local VM password(s) and from either the Microsoft Marketplace or Azure Compute Gallery. Finally, it incorporates a PowerShell script to provide additional post deployment configurations which currently has a reboot and Windows Update option. You can easily add to this script and create parameters within the provided code to then pass to the script for execution.

Components

1. Deployment Code This can be in either ARM format or JSON files or in BICEP which provides a more consolidated code syntax with an easier to read format as well.

2. Parameters / Input This is what provides a way to reuse code by having an answer file sort of approach with things like naming preferences, specific Resource Groups to use, etc.

   Parameters File - This is a JSON based file in which you would supply the required parameters and deploy via PowerShell and possibly build a Template Spec from in Azure.

   Custom UI Definition - This is yet another mechanism for providing the parameters however it is a JSON file which defines a custom User Interface that is similar to what you see in the portal when deploying new resources. It can be much more user friendly and has options to hard code and hide certain inputs. Additionally it can also be compbined with the deployment code to create a Template Spec in Azure but the Template Spec must be created from PowerShell to specify a customer UI definition.

Deploy A Host Pool or Add Session Hosts

This was created to expand on what is in the Azure Portal natively due to some scenarios that may require post move or deployment activities. The functionalities are:

1. Deploy new Host Pool and Session Hosts
2. Deploy additional Session Hosts to existing Host Pool
3. Deploy Session Hosts to an Alternate Tenant (Including Cross Cloud)
4. Deploy Session Hosts to a Dedicated Host (Per IL5 requirements)

PowerShell to convert URL

Add-Type -AssemblyName System.Web

$webURL = Read-Host "Input URL to encode"
$ARMfile = Read-Host "Input the ARM template file name without the extension. (i.e. solution)"
$UIDefFile = Read-Host "Input the UI Definition file name  without the extension. (i.e. uiDefinition)"
$urlToEncode = $webURL
$encodedURL = [System.Web.HttpUtility]::UrlEncode($urlToEncode)

$CompleteURL = "https://portal.azure.com#blade/Microsoft_Azure_CreateUIDef/CustomDeploymentBlade/uri/$encodedURL%2F$ARMfile.json/uiFormDefinitionUri/$encodedURL%2F$UIDefFile.json"
Set-Clipboard -Value $CompleteURL
Write-Host "`nEncoded URL is:" -ForegroundColor Cyan
Write-Host $encodedURL
Write-Host "`nComplete URL is:" -ForegroundColor Cyan
Write-Host "Complete URL copied to clipboard!" -ForegroundColor Yellow
