Need to Nuke an Azure Subscription?

(Ce billet en aussi disponible en français.)


I use very intensely my my.visualstudio (aka MSDN) Azure subscription, to create content for a demo or just to try new feature. So frequently I need to do some cleaning.

multi-resourceGroup-boom

Here a little script that will completely delete all resources of every resources group inside a specific subscription. To be able to execute this script you will need Azure PowerShell cmdlets.

The script asks you to login-in then list all the subscriptions that this account has access. Once you specify which one, it will list all the resource grouped by resource group. Then as a final warning, it will require one last validation before nuking everything.

Be careful.

# Get a list of all Azure subscript that the user can access
$allSubs = Get-AzureRmSubscription 

>$allSubs | Sort-Object SubscriptionName | Format-Table -Property SubscriptionName, SubscriptionId, State

$theSub = Read-Host "Enter the subscriptionId you want to clean"

Write-Host "You select the following subscription. (it will be display 15 sec.)" -ForegroundColor Cyan
Get-AzureRmSubscription -SubscriptionId $theSub | Select-AzureRmSubscription 

#Get all the resources groups
$allRG = Get-AzureRmResourceGroup

foreach ( $g in $allRG){
    Write-Host $g.ResourceGroupName -ForegroundColor Yellow 
    Write-Host "------------------------------------------------------`n" -ForegroundColor Yellow 
    $allResources = Find-AzureRmResource -ResourceGroupNameContains $g.ResourceGroupName
    if($allResources){
        $allResources | Format-Table -Property Name, ResourceName
    }
    else{
        Write-Host "-- empty--`n"
    } 
    Write-Host "`n`n------------------------------------------------------" -ForegroundColor Yellow 
}

$lastValidation = Read-Host "Do you wich to delete ALL the resouces previously listed? (YES/ NO)"
if($lastValidation.ToLower().Equals("yes")){
    foreach ( $g in $allRG){
        Write-Host "Deleting " $g.ResourceGroupName 
        Remove-AzureRmResourceGroup -Name $g.ResourceGroupName -Force -WhatIf
    }
}
else{
    Write-Host "Aborded. Nothing was deleted." -ForegroundColor Cyan
}
