Description

The Set-AzVmssOsProfile cmdlet sets the Virtual Machine Scale Set operating system profile properties.

Examples

Example 1: Set the operating system profile properties for a VMSS

$vmss = New-AzVmssConfig -Location $Loc -SkuCapacity 2 -SkuName "Standard_A0" -UpgradePolicyMode "Automatic" -NetworkInterfaceConfiguration $NetCfg
Set-AzVmssOsProfile -VirtualMachineScaleSet $vmss -ComputerNamePrefix "Test" -AdminUsername $AdminUsername -AdminPassword $AdminPassword

This command sets operating system profile properties for the $vmss object. The command sets the computer name prefix for all the virtual machine instances in the VMSS to Test and supplies the administrator username and password.

Example 2: Set the operating system profile properties for a Vmss in Flexible mode with Hotpatching enabled.
