Adicionar Microsoft Antimalware a Clusters do Azure Service Fabric

O Azure Service Fabric utiliza conjuntos de dimensionamento de máquinas virtuais do Azure para criar os Clusters do Service Fabric. Atualmente, o modelo de conjuntos de dimensionamento de máquinas virtuais utilizado para criar os Clusters do Service Fabric não está ativado com a extensão Antimalware. Como tal, o Antimalware tem de ser ativado separadamente nos conjuntos de dimensionamento. À medida que o ativa em conjuntos de dimensionamento, todos os nós criados nos conjuntos de dimensionamento de máquinas virtuais herdam e obtêm a extensão automaticamente.

O exemplo de código abaixo mostra como pode ativar a extensão IaaS Antimalware com os cmdlets do PowerShell AzureRmVmss.

Adicionar Microsoft Antimalware ao Serviço Cloud do Azure com o Suporte Alargado

O exemplo de código abaixo mostra como pode adicionar ou configurar Microsoft Antimalware ao Serviço Cloud do Azure com suporte alargado (CS-ES) através de cmdlets do PowerShell.

Nota

Antes de executar este exemplo de código, tem de anular o comentário das variáveis e fornecer os valores adequados.

# Create Antimalware extension object, where file is the AntimalwareSettings
$xmlconfig = [IO.File]::ReadAllText("C:\path\to\file.xml")
$extension =  New-AzCloudServiceExtensionObject  -Name "AntimalwareExtension" -Type "PaaSAntimalware" -Publisher "Microsoft.Azure.Security" -Setting $xmlconfig -TypeHandlerVersion "1.5" -AutoUpgradeMinorVersion $true

# Get existing Cloud Service
$cloudService = Get-AzCloudService -ResourceGroup "ContosOrg" -CloudServiceName "ContosoCS"

# Add Antimalaware extension to existing Cloud Service extension object
$cloudService.ExtensionProfile.Extension = $cloudService.ExtensionProfile.Extension + $extension

# Update Cloud Service
$cloudService | Update-AzCloudService
