Azure: delete all Tags

76404357 1

Hello

I have script to delete all Tags.

$RGs = Get-AzResourceGroup
foreach ($RG in $RGs){

Set-AzResourceGroup -Name $RG.name -Tag @{}

}

$removeTags = @()
$resources = Get-AzResource
foreach ($resource in $resources) {

Update-AzTag -ResourceId $resource.id -Tag $removeTags

}

I get Tags yet:

Get-AzTag

Name Count
---- -----
displayName 2
App 1
Department 1
Env 1
Owner 1

I can't find which resource is attached.

Get-AzResource

Any idea?

thanks

Hello,
Based Upon the information provideded
it appears that Microsoft.Compute/virtualMachines/instanceView isn't a tracked resource in Azure, so you won't be able to find any results for this when using Get-AzResource. You can always use the Get-AzResourceProvider cmdlet to view tracked resources you can query over.

The returned object has an InstanceView property, so you can try the following to get the instance view:

$vm = Get-AzVM -ResourceGroupName rg-sfv -Name sfvdc01
$vm.InstanceView

Hi @Limitless Technology

I deleted all resources and there are any resource or RG now, but I can't delete Tags. It seems there is some resource (I don't know where) attached still.
How is possible to find this "resource"?

Thanks

Hi @22308421 ,

why are you not using Remove-AzTag?
https://video2.skills-academy.com/en-us/powershell/module/az.resources/remove-aztag?view=azps-8.1.0

Not tested by myself!

Remove-AzTag -Name "Department" -PassThru Remove-AzTag -Name "App" -PassThru Remove-AzTag -Name "Env" -PassThru Remove-AzTag -Name "Owner" -PassThru

Hi @Andreas Baumgarten

I would like to delete all Tags in a subscription. I deleted all resources and there are any resource or RG now, but I can't delete Tags. It seems there is some resource (I don't know where) attached still. When I try to remove Tag via next Powershell's command remove-aztag, I get result: Remove-AzTag:

Can not remove tag/tag value because it's being referenced by other resources

If I run command get-aztag I can see there is 1 resource but I don't know which is.

Any idea?
Thanks

Hi @22308421 ,

please try this and see if it helps:

$value = "Owner" (Get-AzResource -TagName $value) (Get-AzResourceGroup -Tag @{($value) = '' })

It looks like the Tag details in the different object types/cmdlets are not consistent. For Get-AzResource it's -TagName for Get-AzResourceGroup it's -Tag.

The easiest way to see the related resource of a Tags is via Azure Portal:
