Tutorial: Upgrade the runtime of a Service Fabric cluster in Azure

  • आलेख

This tutorial is part four of a series, and shows you how to upgrade the Service Fabric runtime on an Azure Service Fabric cluster. This tutorial part is written for Service Fabric clusters running on Azure and doesn't apply to standalone Service Fabric clusters.

Warning

This part of the tutorial requires PowerShell. Support for upgrading the cluster runtime is not yet supported by the Azure CLI tools. Alternatively, a cluster can be upgraded in the portal. For more information, see Upgrade an Azure Service Fabric cluster.

If your cluster is already running the latest Service Fabric runtime, you don't need to do this step. However, this article can be used to install any supported runtime on an Azure Service Fabric cluster.

In this tutorial, you learn how to:

  • Read the cluster version
  • Set the cluster version

In this tutorial series you learn how to:

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. To get started, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

Prerequisites

Before you begin this tutorial:

Sign in to Azure

Sign in to your Azure account select your subscription before you execute Azure commands.

Connect-AzAccount
Get-AzSubscription
Set-AzContext -SubscriptionId <guid>

Get the runtime version

After you've connected to Azure, selected the subscription containing the Service Fabric cluster, you can get the runtime version of the cluster.

Get-AzServiceFabricCluster -ResourceGroupName SFCLUSTERTUTORIALGROUP -Name aztestcluster `
    | Select-Object ClusterCodeVersion

Or, just get a list of all clusters in your subscription with the following example:

Get-AzServiceFabricCluster | Select-Object Name, ClusterCodeVersion

Note the ClusterCodeVersion value. This value will be used in the next section.

Upgrade the runtime

Use the value of ClusterCodeVersion from the previous section with the Get-ServiceFabricRuntimeUpgradeVersion cmdlet to discover what versions are available to upgrade to. This cmdlet can only be run from a computer connected to the internet. For example, if you wanted to see what runtime versions you could upgrade to from version 5.7.198.9494, use the following command:

Get-ServiceFabricRuntimeUpgradeVersion -BaseVersion "5.7.198.9494"

With a list of versions, you can tell the Azure Service Fabric cluster to upgrade to a newer runtime. For example, if version 6.0.219.9494 is available to upgrade to, use the following command to upgrade your cluster.

Set-AzServiceFabricUpgradeType -ResourceGroupName SFCLUSTERTUTORIALGROUP `
                                    -Name aztestcluster `
                                    -UpgradeMode Manual `
                                    -Version "6.0.219.9494"

Important

The cluster runtime upgrade may take a long time to complete. PowerShell is blocked while the upgrade is running. You can use another PowerShell session to check the status of the upgrade.

The status of the upgrade can be monitored with either PowerShell or the Azure Service Fabric CLI (sfctl).

First connect to the cluster with the TLS/SSL certificate created in the first part of the tutorial. Use the Connect-ServiceFabricCluster cmdlet or sfctl cluster upgrade-status.

$endpoint = "<mycluster>.southcentralus.cloudapp.azure.com:19000"
$thumbprint = "63EB5BA4BC2A3BADC42CA6F93D6F45E5AD98A1E4"

Connect-ServiceFabricCluster -ConnectionEndpoint $endpoint `
                             -KeepAliveIntervalInSec 10 `
                             -X509Credential -ServerCertThumbprint $thumbprint `
                             -FindType FindByThumbprint -FindValue $thumbprint `
                             -StoreLocation CurrentUser -StoreName My

sfctl cluster select --endpoint https://aztestcluster.southcentralus.cloudapp.azure.com:19080 \
--pem ./aztestcluster201709151446.pem --no-verify

Next, use Get-ServiceFabricClusterUpgrade or sfctl cluster upgrade-status to display the status. Something similar to the following result is shown.
