Add-AzVmssExtension cmdlet 将扩展添加到虚拟机规模集（VMSS）。

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

此命令将扩展添加到 VMSS。

$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

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

#Best Practice for secured parameters.
$protectedSettings = @{

}

$publicSettings = @{

"commandToExecute"= "sh $($BatchFile)"
}

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

Add-AzVmssExtension -VirtualMachineScaleSet $vmss `

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

此命令在 Blob 存储上使用示例 bash 脚本将扩展添加到 VMSS，在受保护设置中指定 Blob 存储和可执行命令的 URL 以及安全访问。

此 cmdlet 支持通用参数：-Debug、-ErrorAction、-ErrorVariable、-InformationAction、-InformationVariable、-OutBuffer、-OutVariable、-PipelineVariable、-ProgressAction、-Verbose、-WarningAction 和 -WarningVariable。 有关详细信息，请参阅 about_CommonParameters。
