Description

The Add-AzVmssExtension cmdlet adds an extension to the Virtual Machine Scale Set (VMSS).

Examples

Example 1: Add an extension to the VMSS

Add-AzVmssExtension -VirtualMachineScaleSet $VMSS -Name $ExtName -Publisher $Publisher -Type $ExtType -TypeHandlerVersion $ExtVer -AutoUpgradeMinorVersion $True

This command adds an extension to the VMSS.

Example 2: Add an extension to the VMSS with settings and protected settings

$Settings = @{"fileUris" = "[]"; "commandToExecute" = ""};
$ProtectedSettings = @{"storageAccountName" = $stoname; "storageAccountKey" = $stokey};

Add-AzVmssExtension -VirtualMachineScaleSet $vmss -Name $vmssExtensionName -Publisher $vmssPublisher  `
  -Type $vmssExtensionType -TypeHandlerVersion $ExtVer -AutoUpgradeMinorVersion $True  `
  -Setting $Settings -ProtectedSetting $ProtectedSettings

Example 3: Add an extension to the VMSS with settings and protected settings

$BatchFile = "runbook.sh"
$ResourceGroupName = "HelloRG"
$VMScaleSetName = "HelloVmSS"
$TypeHandlerVersion = 2.1

#Best Practice for securd paramaters.
$protectedSettings = @{
"managedIdentity" = @{ "clientId" = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"};
}

$publicSettings = @{ 
"fileUris"= (,"https://storage.blob.core.windows.net/itfiles/$($BatchFile)");
"commandToExecute"= "sh $($BatchFile)"
}

# Get information about the scale set
$vmss = Get-AzVmss `
            -ResourceGroupName $ResourceGroupName `
            -VMScaleSetName $VMScaleSetName

Add-AzVmssExtension -VirtualMachineScaleSet $vmss `
    -Name "CustomScript" `
    -Publisher "Microsoft.Azure.Extensions" `
    -Type "CustomScript" `
    -TypeHandlerVersion $TypeHandlerVersion `
    -AutoUpgradeMinorVersion $true `
    -Setting $publicSettings `
    -ProtectedSetting $protectedSettings

Update-AzVmss `
    -ResourceGroupName $ResourceGroupName `
    -Name $VMScaleSetName `
    -VirtualMachineScaleSet $vmss

This command adds an extension to the VMSS with a sample bash script on a blob storage, specify the url of blob storage and executable command in settings and security access in protected settings.
