Description

The Set-AzVMOperatingSystem cmdlet sets operating system properties during the creation of a new virtual machine. You can specify logon credentials, computer name, and operating system type.

Examples

Example 1: Set operating system properties for a new virtual machine

$SecurePassword = ConvertTo-SecureString -String "****" -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ("FullerP", $SecurePassword); 
$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet03" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1" -AvailabilitySetID $AvailabilitySet.Id
$ComputerName = "ContosoVM122"
$WinRMCertUrl = "http://keyVaultName.vault.azure.net/secrets/secretName/secretVersion"
$TimeZone = "Pacific Standard Time"
$CustomData = "echo 'Hello World'"
$VirtualMachine = Set-AzVMOperatingSystem -VM $VirtualMachine -Windows -ComputerName $ComputerName -Credential $Credential -CustomData $CustomData -WinRMHttp -WinRMHttps -WinRMCertificateUrl $WinRMCertUrl -ProvisionVMAgent -EnableAutoUpdate -TimeZone $TimeZone -PatchMode "AutomaticByPlatform"

The first command converts a password to a secure string, and then stores it in the $SecurePassword variable. For more information, type Get-Help ConvertTo-SecureString. The second command creates a credential for the user FullerP and the password stored in $SecurePassword, and then stores the credential in the $Credential variable. For more information, type Get-Help New-Object. The third command gets the availability set named AvailabilitySet03 in the resource group named ResourceGroup11, and then stores that object in the $AvailabilitySet variable. The fourth command creates a virtual machine object, and then stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The virtual machine belongs to the availability set stored in $AvailabilitySet. The next four commands assign values to variables to use in the following command. Because you could specify these strings directly in the Set-AzVMOperatingSystem command, this approach is used only for readability. However, you might use an approach such as this in scripts. The final command sets operating system properties for the virtual machine stored in $VirtualMachine. The command uses the credentials stored in $Credential. The command uses variables assigned in previous commands for some parameters.

Example 2: Set operating system properties for a new virtual machine with hot patching enabled

$SecurePassword = ConvertTo-SecureString -String "****" -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ("FullerP", $SecurePassword); 
$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet03" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1" -AvailabilitySetID $AvailabilitySet.Id
$ComputerName = "ContosoVM122"
$WinRMCertUrl = "http://keyVaultName.vault.azure.net/secrets/secretName/secretVersion"
$TimeZone = "Pacific Standard Time"
$CustomData = "echo 'Hello World'"
$VirtualMachine = Set-AzVMOperatingSystem -VM $VirtualMachine -Windows -ComputerName $ComputerName -Credential $Credential -CustomData $CustomData -WinRMHttp -WinRMHttps -WinRMCertificateUrl $WinRMCertUrl -ProvisionVMAgent -EnableAutoUpdate -TimeZone $TimeZone -PatchMode "AutomaticByPlatform" -EnableHotPatching

The first command converts a password to a secure string, and then stores it in the $SecurePassword variable. For more information, type Get-Help ConvertTo-SecureString. The second command creates a credential for the user FullerP and the password stored in $SecurePassword, and then stores the credential in the $Credential variable. For more information, type Get-Help New-Object. The third command gets the availability set named AvailabilitySet03 in the resource group named ResourceGroup11, and then stores that object in the $AvailabilitySet variable. The fourth command creates a virtual machine object, and then stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The virtual machine belongs to the availability set stored in $AvailabilitySet. The next four commands assign values to variables to use in the following command. Because you could specify these strings directly in the Set-AzVMOperatingSystem command, this approach is used only for readability. However, you might use an approach such as this in scripts. The final command sets operating system properties for the virtual machine stored in $VirtualMachine. The command uses the credentials stored in $Credential. The command uses variables assigned in previous commands for some parameters. The command enables Hotpatching on the virtual machine.

Example 3: Set operating system properties for a new Linux virtual machine

$SecurePassword = ConvertTo-SecureString -String "****" -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ("FullerP", $SecurePassword); 
$AvailabilitySet = Get-AzAvailabilitySet -ResourceGroupName "ResourceGroup11" -Name "AvailabilitySet03" 
$VirtualMachine = New-AzVMConfig -VMName "VirtualMachine07" -VMSize "Standard_A1" -AvailabilitySetID $AvailabilitySet.Id
$ComputerName = "ContosoVM122"
$CustomData = "echo 'Hello World'"
$VirtualMachine = Set-AzVMOperatingSystem -VM $VirtualMachine -Linux -ComputerName $ComputerName -Credential $Credential -CustomData $CustomData -PatchMode "AutomaticByPlatform"

The first command converts a password to a secure string, and then stores it in the $SecurePassword variable. For more information, type Get-Help ConvertTo-SecureString. The second command creates a credential for the user FullerP and the password stored in $SecurePassword, and then stores the credential in the $Credential variable. For more information, type Get-Help New-Object. The third command gets the availability set named AvailabilitySet03 in the resource group named ResourceGroup11, and then stores that object in the $AvailabilitySet variable. The fourth command creates a virtual machine object, and then stores it in the $VirtualMachine variable. The command assigns a name and size to the virtual machine. The virtual machine belongs to the availability set stored in $AvailabilitySet. The next two commands assign values to variables to use in the following command. The final command sets operating system properties for the virtual machine stored in $VirtualMachine. The command uses the credentials stored in $Credential. The command uses variables assigned in previous commands for some parameters. The command sets the patch mode value on the virtual machine to "AutomaticByPlatform".

Example 4: Set operating system properties with a Credential parameter when the VM does not have an OSProfile.

$rgname = <Resource Group Name>;
$loc = <Azure Region>;
New-AzResourceGroup -Name $rgname -Location $loc -Force;
# create credential
$password = <Password>;
$securePassword = $password | ConvertTo-SecureString -AsPlainText -Force;
$user = <Username>;
$cred = New-Object System.Management.Automation.PSCredential ($user, $securePassword);

# Setup parameters
$domainNameLabel = "d2" + $rgname;
$vmsize = 'Standard_D4s_v3';
$vmname = 'v' + $rgname;
$vnetname = "vn" + $rgname;
$vnetAddress = "10.0.0.0/16";
$subnetname = "slb" + $rgname;
$subnetAddress = "10.0.2.0/24";
$OSDiskName = $vmname + "d";
$NICName = $vmname+ "n";
$NSGName = $vmname + "nsg";

# Creating a VM using Default parameterset
$frontendSubnet = New-AzVirtualNetworkSubnetConfig -Name $subnetname -AddressPrefix $subnetAddress;

$vnet = New-AzVirtualNetwork -Name $vnetname -ResourceGroupName $rgname -Location $loc -AddressPrefix $vnetAddress -Subnet $frontendSubnet;

$nsgRuleRDP = New-AzNetworkSecurityRuleConfig -Name RDP  -Protocol Tcp  -Direction Inbound -Priority 1001 -SourceAddressPrefix * -SourcePortRange * -DestinationAddressPrefix * -DestinationPortRange 3389 -Access Allow;
$nsg = New-AzNetworkSecurityGroup -ResourceGroupName $rgname -Location $loc -Name $NSGName  -SecurityRules $nsgRuleRDP;
$nic = New-AzNetworkInterface -Name $NICName -ResourceGroupName $rgname -Location $loc -SubnetId $vnet.Subnets[0].Id -NetworkSecurityGroupId $nsg.Id -EnableAcceleratedNetworking;

$vmConfig = New-AzVMConfig -VMName $vmname -VMSize $vmsize;
$vmConfig = Set-AzVMOperatingSystem -VM $vmConfig -Windows -ComputerName $vmname -Credential $cred;
$vmConfig = Add-AzVMNetworkInterface -VM $vmConfig -Id $nic.Id;

# Verify a VM is created. 
New-AzVM -ResourceGroupName $rgname -Location $loc -VM $vmConfig;
$vm = Get-AzVM -ResourceGroupName $rgname -Name $vmname;
