How delete VM Azure using tags using powershell? - azure

Question

How do I delete a VM using tags? Let's say there is a VM with the tags "Name:Surname". How can I delete this VM without using the VM name or ID. Namely deletion using tags.
I try to use:
get-azvm -ResourceGroupName "ResourceGroup" | Where-Object {$_.Tags -like "[Name, blabla], [Surname, blabla]"}
but it didn't find that VM

Answer 1

I have reproduced in my environment. Firstly, you need to find the Virtual Machine using the below command:
xx- Name of the resource group
hello- tag name
get-azvm -ResourceGroupName "xx" | Where-Object {$_.Tags['hello']}
After getting the VM name you can use the below command to delete the VM:
xx- Name of the resource group
yy- Name of the vm.
Remove-AzVM -ResourceGroupName "xx" -Name "yy"
Then type Y(yes) to delete the VM as below:

Based on this,
You could do something like this:
$Surname= 'Test'
$VMs = Get-AzVM -ResourceGroupName 'myRG'
foreach ($VM in $VMs)
{
[Hashtable]$VMTag = (Get-AzVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name).Tags
foreach ($h in $VMTag.GetEnumerator()) {
if (($h.Name -eq "Name") -and ($h.value -eq $Surname))
{
Write-host "Removing VM" $VM.Name
Remove-AzVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Force -Confirm:$false
}
}
}
