設定 Azure HDInsight 的虛擬網路服務端點原則

  • 發行項

本文提供如何使用 Azure HDInsight 在虛擬網路上實作服務端點原則的相關資訊。

背景

Azure HDInsight 可讓您在自己的虛擬網路中建立叢集。 如果您需要允許從虛擬網路到其他 Azure 服務 (例如儲存體帳戶) 的傳出流量，您可以建立服務端點原則。 不過，透過 Azure 入口網站建立的服務端點原則，只允許您為單一帳戶、訂用帳戶中的所有帳戶或資源群組中的所有帳戶建立原則。

不過，作為受控服務，Azure HDInsight 會從每個區域中特定儲存體帳戶中的每個叢集收集資料和記錄檔。 為了讓此資料從虛擬網路觸達 HDInsight，您必須建立服務端點原則，以允許傳出流量流向 Azure HDInsight 所管理的特定資料收集點。

HDInsight 的服務端點原則

這些服務端點原則支援下列功能：

  • 叢集建立、作業執行和平台作業 (例如調整) 的記錄和遙測集合。
  • 將虛擬硬碟 (VHD) 連結至新建立的叢集節點，以便在叢集上佈建軟體和程式庫。

如果未建立服務端點原則來啟用此資料流程，叢集建立可能會失敗，且 Azure HDInsight 將無法為您的叢集提供支援。

建立 HDInsight 的服務端點原則

建立新的叢集之前，請確定已將正確的服務端點原則連結至您的虛擬網路。 否則，叢集建立可能會失敗或造成錯誤。

使用下列程序來建立必要的服務端點原則：

  1. 決定您要建立 HDInsight 叢集的區域。

  2. 在服務端點原則資源清單中查閱該區域，這會為 HDInsight 管理儲存體帳戶提供所有資源群組。

  3. 選取您區域的資源群組清單。 Canada Central 的資源範例如下所示：

    "Canada Central":[
    "/subscriptions/aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/resourceGroups/Default-Storage-WestUS",
    "/subscriptions/bbbb1b1b-cc2c-dd3d-ee4e-ffffff5f5f5f/resourceGroups/GenevaWarmPathManageRG",
    "/subscriptions/cccc2c2c-dd3d-ee4e-ff5f-aaaaaa6a6a6a/resourceGroups/GenevaWarmPathManageRG",
    "/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/Default-Storage-CanadaCentral",
    "/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/cancstorage",
    "/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/GenevaWarmPathManageRG",
    "/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/hdi31distrorelease",
    "/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/bigdatadistro"
],

  4. 將資源群組清單插入以 Azure CLI 或 Azure PowerShell 撰寫的安裝指令碼中。

    $subscriptionId = "<subscription id>"
$rgName="<resource group name> "
$location="<location name>"
$vnetName="<vnet name>"
$subnetName="<subnet name>"
$sepName="<service endpoint policy name>"
$sepDefName="<service endpoint policy definition name>"

# Set to the right subscription ID
az account set --subscription $subscriptionId

# setup service endpoint on the virtual network subnet
az network vnet subnet update -g $rgName --vnet-name $vnetName -n $subnetName --service-endpoints Microsoft.Storage

# Create Service Endpoint Policy
az network service-endpoint policy create -g $rgName  -n $sepName -l $location

# Insert the list of HDInsight owned resources for the region your clusters will be created in.
# Be sure to get the most recent list of resource groups from the [list of service endpoint policy resources](https://github.com/Azure-Samples/hdinsight-enterprise-security/blob/main/hdinsight-service-endpoint-policy-resources.json)
[String[]]$resources = @("/subscriptions/aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/resourceGroups/Default-Storage-WestUS",`
"/subscriptions/bbbb1b1b-cc2c-dd3d-ee4e-ffffff5f5f5f/resourceGroups/GenevaWarmPathManageRG",`
"/subscriptions/cccc2c2c-dd3d-ee4e-ff5f-aaaaaa6a6a6a/resourceGroups/GenevaWarmPathManageRG",`
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/Default-Storage-CanadaCentral",`
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/cancstorage",`
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/GenevaWarmPathManageRG",
"/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/hdi31distrorelease",
"/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/bigdatadistro")

#Assign service resources to the SEP policy.
az network service-endpoint policy-definition create -g $rgName --policy-name $sepName -n $sepDefName --service "Microsoft.Storage" --service-resources $resources

# Associate a subnet to the service endpoint policy just created. If there is a delay in updating it to subnet, you can use the Azure portal to associate the policy with the subnet.
az network vnet subnet update -g $rgName --vnet-name $vnetName -n $subnetName --service-endpoint-policy $sepName

    如果您想要使用 PowerShell 設定服務端點原則，請使用下列程式碼片段。

    #Script to assign SEP 
$subscriptionId = "<subscription id>"
$rgName = "<resource group name>"
$vnetName = "<vnet name>"
$subnetName = "<subnet Name"
$location = "Canada Central"

# Connect to your Azure Account
Connect-AzAccount

# Select the Subscription that you want to use
Select-AzSubscription -SubscriptionId $subscriptionId

# Retrieve VNet Config
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name $vnetName

# Retrieve Subnet Config
$subnet = Get-AzVirtualNetworkSubnetConfig -Name $subnetName -VirtualNetwork $vnet

# Insert the list of HDInsight owned resources for the region your clusters will be created in.
# Be sure to get the most recent list of resource groups from the [list of service endpoint policy resources](https://github.com/Azure-Samples/hdinsight-enterprise-security/blob/main/hdinsight-service-endpoint-policy-resources.json)
[String[]]$resources = @("/subscriptions/aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/resourceGroups/Default-Storage-WestUS",
"/subscriptions/bbbb1b1b-cc2c-dd3d-ee4e-ffffff5f5f5f/resourceGroups/GenevaWarmPathManageRG",
"/subscriptions/cccc2c2c-dd3d-ee4e-ff5f-aaaaaa6a6a6a/resourceGroups/GenevaWarmPathManageRG",
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/Default-Storage-CanadaCentral",
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/cancstorage",
"/subscriptions/dddd3d3d-ee4e-ff5f-aa6a-bbbbbb7b7b7b/resourceGroups/GenevaWarmPathManageRG",
"/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/hdi31distrorelease",
"/subscriptions/eeee4efe-ff5f-aa6a-bb7b-cccccc8c8c8c/resourceGroups/DistroStorageRG/providers/Microsoft.Storage/storageAccounts/bigdatadistro")

#Declare service endpoint policy definition
$sepDef = New-AzServiceEndpointPolicyDefinition -Name "SEPHDICanadaCentral" -Description "Service Endpoint Policy Definition" -Service "Microsoft.Storage" -ServiceResource $resources

# Service Endpoint Policy
$sep= New-AzServiceEndpointPolicy -ResourceGroupName $rgName -Name "SEPHDICanadaCentral" -Location $location -ServiceEndpointPolicyDefinition $sepDef

# Associate a subnet to the service endpoint policy just created. If there is a delay in updating it to subnet, you can use the Azure portal to associate the policy with the subnet.
Set-AzVirtualNetworkSubnetConfig -Name $subnetName -VirtualNetwork $vnet -AddressPrefix $subnet.AddressPrefix -ServiceEndpointPolicy $sep

重要

建議您以手動方式或經由自動化，依照排程取得最新的服務端點原則資源清單。 這可防止在 JSON 檔案中新增或移除其他資源群組時發生 CRUD 問題。
