Description

The Set-AzureRmVMDiskEncryptionExtension cmdlet enables encryption on a running infrastructure as a service (IaaS) virtual machine in Azure. This cmdlet enables encryption by installing the disk encryption extension on the virtual machine. If no Name parameter is specified, an extension with the default name AzureDiskEncryption for virtual machines that run the Windows operating system or AzureDiskEncryptionForLinux for Linux virtual machines are installed. This cmdlet requires confirmation from the users as one of the steps to enable encryption requires a restart of the virtual machine. It is advised that you save your work on the virtual machine before you run this cmdlet.

Examples

Example 1: Enable encryption

$RGName = "MyResourceGroup"
$VMName = "MyTestVM"
$VaultName= "MyKeyVault"
$KeyVault = Get-AzureRmKeyVault -VaultName $VaultName -ResourceGroupName $RGName
$DiskEncryptionKeyVaultUrl = $KeyVault.VaultUri
$KeyVaultResourceId = $KeyVault.ResourceId
Set-AzureRmVMDiskEncryptionExtension -ResourceGroupName $RGName -VMName $VMName -DiskEncryptionKeyVaultUrl $DiskEncryptionKeyVaultUrl -DiskEncryptionKeyVaultId $KeyVaultResourceId

This example demonstrates enabling encryption without specifying AD credentials.

Example 2: Enable encryption with pipelined input

$params = New-Object PSObject -Property @{
    ResourceGroupName = "[resource-group-name]"
    VMName = "[vm-name]"
    DiskEncryptionKeyVaultId = "/subscriptions/[subscription-id-guid]/resourceGroups/[resource-group-name]/providers/Microsoft.KeyVault/vaults/[keyvault-name]"
    DiskEncryptionKeyVaultUrl = "https://[keyvault-name].vault.azure.net"
    KeyEncryptionKeyVaultId = "/subscriptions/[subscription-id-guid]/resourceGroups/[resource-group-name]/providers/Microsoft.KeyVault/vaults/[keyvault-name]"
    KeyEncryptionKeyUrl = "https://[keyvault-name].vault.azure.net/keys/[kekname]/[kek-unique-id]"
    VolumeType = "All"
}

$params | Set-AzureRmVmDiskEncryptionExtension

This example demonstrates sending parameters using pipelined input to enable encryption without specifying AD credentials.

Example 3: Enable encryption using Microsoft Entra Client ID and Client Secret
