How to change the Azure tag value using PowerShell?

To change the azure value using PowerShell we need to use the Update-AZTag command with the merge property.

Example

For example, we have the Azure VM TestMachine2k16 and we have its tags as shown below.

PS C:\> $vm = Get-AzVM -VMName TestMachine2k16 PS C:\> $vm | Select -ExpandProperty Tags

Output

Key          Value ---          ----- Owner       Chirag For Ansible Patching_Day Sunday Application SecretTag

We need to change the Patching_Day from Sunday to Wednesday. We will use the below command.

Example

$tag = @{Patching_Day='Wednesday'} Update-AzTag -Tag $tag -ResourceId $vm.Id -Operation Merge -Verbose

Output

Name           Value ============ ========= Patching_Day Wednesday For           Ansible Application SecretTag Owner          Chirag

There is also property Replace available in Update-AZTag but please be cautious while using the Replace parameter because once you apply it, the current tag will be changed but other tags will be erased.

Example

Update-AzTag -Tag $tag -ResourceId $vm.Id -Operation Replace -Verbose

Output

Properties : Name          Value ============ ========= Patching_Day Wednesday
