While it is very easy to add and change tags using console, it is not so easy to delete a specific tag from a resource. The console also limits the number of resources you can update to 100. So if you need to change tags on more than 100 resources, then you'll need to rinse and repeat as often as neccessary This script will allow you to -Add, -Replace or -Remove a specific tag from any Load Balancer resource that matches a search criteria using parameters -ManageThisTag and -ManageThisTagValue. This script is part of a set of ManageTagsOn scripts. Please look for ManageTagsOnVM ManageTagsOnDisk ManageTagsOnNetworkCard ManageTagsOnLoadBalancer ManageTagsOnNetworkSecurityGroup ManageTagsOnAvailabilitySet ManageTagsOnRouteTable ManageTagsOnAutomationRunbooks .SYNOPSIS Add, Remove or Replace Tags on Load Balancer Resource in Azure .PARAMETER Remove The -Remove switch will tell the script to delete the tag specified by ManageThisTag and optionally if the value of the Tag matches the content of -ManageThisTagValue parameter .PARAMETER Replace The -Replace switch will tell the script to delete the tag specified by ManageThisTag and optionally if the value of the Tag matches -ManageThisTagValue parameter and replace it with a new Tag and Value specified by -NewTagKey and -NewTagValue parameters .PARAMETER ManageThisTag The name of the TAG to be used as a search criteria. Filters only those resources where this tag exists. .PARAMETER ManageThisTagValue The value of the TAG specified by ManageThisTag. This further filters only those resources where this tag exists and it value matches ManageThisTagValue. .PARAMETER FromGroup The name of the Resource Group to limit search scope. Filters only those Resources in the specific Resource Group. .PARAMETER Add The -Add switch works together with -NewTagKey and -NewTagValue parameters. This will make the script add a new tag NewTagKey with value of NewTagValue to the resource that match the search criteria .PARAMETER WhatIf Safe run of the script without any changes to preview changes that would be made. .EXAMPLE ManageTagsOnLoadBalancer.ps1 -Remove -ManageThisTag "Environment" -FromGroup "test-vm-servers-rg" .EXAMPLE ManageTagsOnLoadBalancer.ps1 -Replace -ManageThisTag "Environment" -ManageThisTagValue "Test" -NewTagKey "Environment" -NewTagValue "Development" .EXAMPLE ManageTagsOnLoadBalancer.ps1 -Add -ManageThisTag "Environment" -ManageThisTagValue "Test" -NewTagKey "Owner" -NewTagValue "Boston Development Team" .NOTES AUTHOR: Alexander Goldberg LASTEDIT: Feb 16, 2020 WEBSITE: www.alexgoldberg.com #> [cmdletbinding( DefaultParameterSetName='Remove' )] param( [Parameter(Mandatory=$true,ParameterSetName = "Remove")] [switch]$Remove, [Parameter(Mandatory=$true,ParameterSetName = "Replace")] [switch]$Replace, [Parameter(Mandatory=$true,ParameterSetName = "Remove")] [Parameter(Mandatory=$true,ParameterSetName = "Replace")] [Parameter(Mandatory=$false,ParameterSetName = "Add")] [string]$ManageThisTag, [Parameter(ParameterSetName = "Remove")] [Parameter(ParameterSetName = "Replace")] [Parameter(ParameterSetName = "Add")] [string]$ManageThisTagValue, [Parameter(Mandatory=$true,ParameterSetName = "Replace")] [Parameter(Mandatory=$true,ParameterSetName = "Add")] [string]$NewTagKey, [Parameter(Mandatory=$true,ParameterSetName = "Replace")] [Parameter(Mandatory=$true,ParameterSetName = "Add")] [string]$NewTagValue, [string]$FromGroup, [Parameter(ParameterSetName = "Add")] [switch]$Add, [switch]$WhatIf ) # Getting the list of LoadBalancer Resources. if ($PSCmdlet.MyInvocation.BoundParameters.Keys.Contains('ManageThisTagValue')) { if ($PSCmdlet.MyInvocation.BoundParameters.Keys.Contains('FromGroup')) { $Resources = Get-AzureRmLoadBalancer -ResourceGroupName $FromGroup | Where-Object -FilterScript {$_.Tag.Keys.Count -gt 0 -and $_.Tag.($ManageThisTag) -eq $ManageThisTagValue} } else { $Resources = Get-AzureRmLoadBalancer | Where-Object -FilterScript {$_.Tag.Keys.Count -gt 0 -and $_.Tag.($ManageThisTag) -eq $ManageThisTagValue} } } elseif ($PSCmdlet.MyInvocation.BoundParameters.Keys.Contains('ManageThisTag')) { if ($PSCmdlet.MyInvocation.BoundParameters.Keys.Contains('FromGroup')) { $Resources = Get-AzureRmLoadBalancer -ResourceGroupName $FromGroup | Where-Object -FilterScript {$_.Tag.Keys.Count -gt 0 -and $_.Tag.ContainsKey($ManageThisTag)} } else { $Resources = Get-AzureRmLoadBalancer | Where-Object -FilterScript {$_.Tag.Keys.Count -gt 0 -and $_.Tag.ContainsKey($ManageThisTag)} } } else { if ($PSCmdlet.MyInvocation.BoundParameters.Keys.Contains('FromGroup')) { $Resources = Get-AzureRmLoadBalancer -ResourceGroupName $FromGroup } else { $Resources = Get-AzureRmLoadBalancer } } if ($null -ne $Resources) { foreach ($Resource in $Resources) { Write-Output ('processing: ' + $Resource.Name) #set UpdateTags to true $UpdateTags = $false if ($Remove -or $Replace) { Write-Output ("Tag " + $ManageThisTag + " with value of " + $ManageThisTagValue + " exists in the " + $Resource.Name + " and will be Removed/Replaced") $Resource.Tag.Remove($ManageThisTag) if ($Replace) { $Resource.Tag.Add($NewTagKey, $NewTagValue) } #set UpdateTags to true $UpdateTags = $true } if ($Add) { $Resource.Tag.Add($NewTagKey, $NewTagValue) # In addition to the newtag and value, you can also hardcode any additonal tag value key pairs here # I know, it's not pretty, but it works if you want to add multiple tags #$Resource.Tags.Add("tag name","tag value") # Adding new tag and value #$Resource.Tags.Add("tag name","tag value") # Adding new tag and value #set UpdateTags to true $UpdateTags = $true } if ($UpdateTags) { Write-Output ("Updating Tags on: " + $Resource.Name) if (!$WhatIf) { $Resource | Set-AzureRmLoadBalancer } else { Write-Output "--- new tags ---" Write-Output ($Resource.Tag | Out-String) } } } } else { Write-Warning ("No resources found that matched search criteria") } |
