Upgrade the Service Fabric version that runs on your cluster

For any modern system, the ability to upgrade is key to the long-term success of your product. An Azure Service Fabric cluster is a resource that you own. This article describes how to upgrade the version of Service Fabric running on your standalone cluster.

Note

Make sure that your cluster always runs a supported Service Fabric version. When Microsoft announces the release of a new version of Service Fabric, the previous version is marked for end of support after a minimum of 60 days from the date of the announcement. New releases are announced on the Service Fabric team blog. The new release is available to choose at that point.

You can upgrade your cluster to the new version only if you're using a production-style node configuration, where each Service Fabric node is allocated on a separate physical or virtual machine. If you have a development cluster, where more than one Service Fabric node is on a single physical or virtual machine, you must re-create the cluster with the new version.

Two distinct workflows can upgrade your cluster to the latest version or a supported Service Fabric version. One workflow is for clusters that have connectivity to download the latest version automatically. The other workflow is for clusters that don't have connectivity to download the latest Service Fabric version.

Enable auto-upgrade of the Service Fabric version of your cluster

To set your cluster to download updates of Service Fabric when Microsoft releases a new version, set the fabricClusterAutoupgradeEnabled cluster configuration to true. To manually select a supported version of Service Fabric that you want your cluster to be on, set the fabricClusterAutoupgradeEnabled cluster configuration to false.

Upgrade clusters that have connectivity to download the latest code and configuration

Use these steps to upgrade your cluster to a supported version if your cluster nodes have internet connectivity to the Microsoft Download Center.

For clusters that have connectivity to the Microsoft Download Center, Microsoft periodically checks for the availability of new Service Fabric versions.

When a new Service Fabric version is available, the package is downloaded locally to the cluster and provisioned for upgrade. Additionally, to inform the customer of this new version, the system shows an explicit cluster health warning that's similar to the following:

"The current cluster version [version #] support ends [date]."

After the cluster is running the latest version, the warning goes away.

When you see the cluster health warning, upgrade the cluster:

Connect to the cluster from any machine that has administrator access to all the machines that are listed as nodes in the cluster. The machine that this script is run on doesn't have to be part of the cluster.

###### connect to the secure cluster using certs
$ClusterName= "mysecurecluster.something.com:19000"
$CertThumbprint= "70EF5E22ADB649799DA3C8B6A6BF7FG2D630F8F3"
Connect-serviceFabricCluster -ConnectionEndpoint $ClusterName -KeepAliveIntervalInSec 10 `
    -X509Credential `
    -ServerCertThumbprint $CertThumbprint  `
    -FindType FindByThumbprint `
    -FindValue $CertThumbprint `
    -StoreLocation CurrentUser `
    -StoreName My

```
###### Get the list of available Service Fabric versions
Get-ServiceFabricRegisteredClusterCodeVersion
```
You should get an output similar to this:
Start a cluster upgrade to an available version by using the Start-ServiceFabricClusterUpgrade Windows PowerShell command.
```
Start-ServiceFabricClusterUpgrade -Code -CodePackageVersion <codeversion#> -Monitored -FailureAction Rollback

###### Here is a filled-out example

Start-ServiceFabricClusterUpgrade -Code -CodePackageVersion 5.3.301.9590 -Monitored -FailureAction Rollback
```
To monitor the progress of the upgrade, you can use Service Fabric Explorer or run the following PowerShell command:
```
Get-ServiceFabricClusterUpgrade
```
If the cluster health policies aren't met, the upgrade is rolled back. To specify custom health policies for the Start-ServiceFabricClusterUpgrade command, see the documentation for Start-ServiceFabricClusterUpgrade.

After you fix the issues that resulted in the rollback, initiate the upgrade again by following the same steps as previously described.

Upgrade clusters that have no connectivity to download the latest code and configuration

Use these steps to upgrade your cluster to a supported version if your cluster nodes don't have internet connectivity to the Microsoft Download Center.

Note

If you're running a cluster that isn't connected to the internet, you have to monitor the Service Fabric team blog to learn about new releases. The system doesn't show a cluster health warning to alert you of new releases.

Auto provisioning vs. manual provisioning

To enable automatic downloading and registration for the latest code version, set up the Service Fabric Update Service. For instructions, see Tools\ServiceFabricUpdateService.zip\Readme_InstructionsAndHowTos.txt in the standalone package.

For the manual process, follow these instructions.

Modify your cluster configuration to set the following property to false before you start a configuration upgrade:

"fabricClusterAutoupgradeEnabled": false,

For usage details, see the Start-ServiceFabricClusterConfigurationUpgrade PowerShell command. Make sure to update 'clusterConfigurationVersion' in your JSON before you start the configuration upgrade.

    Start-ServiceFabricClusterConfigurationUpgrade -ClusterConfigPath <Path to Configuration File>

Cluster upgrade workflow

Run Get-ServiceFabricClusterUpgrade from one of the nodes in the cluster and note the TargetCodeVersion.
Run the following from an internet-connected machine to list all upgrade-compatible versions with the current version and download the corresponding package from the associated download links:
```
###### Get list of all upgrade compatible packages  
Get-ServiceFabricRuntimeUpgradeVersion -BaseVersion <TargetCodeVersion as noted in Step 1> 
```

###### Get the list of available Service Fabric versions
Copy-ServiceFabricClusterPackage -Code -CodePackagePath <name of the .cab file including the path to it> -ImageStoreConnectionString "fabric:ImageStore"

###### Here is a filled-out example
Copy-ServiceFabricClusterPackage -Code -CodePackagePath .\MicrosoftAzureServiceFabric.5.3.301.9590.cab -ImageStoreConnectionString "fabric:ImageStore"

Copy the downloaded package into the cluster image store.

###### Get the list of available Service Fabric versions
Register-ServiceFabricClusterPackage -Code -CodePackagePath <name of the .cab file>

###### Here is a filled-out example
Register-ServiceFabricClusterPackage -Code -CodePackagePath MicrosoftAzureServiceFabric.5.3.301.9590.cab

Start a cluster upgrade to an available version.
```
Start-ServiceFabricClusterUpgrade -Code -CodePackageVersion <codeversion#> -Monitored -FailureAction Rollback

###### Here is a filled-out example
Start-ServiceFabricClusterUpgrade -Code -CodePackageVersion 5.3.301.9590 -Monitored -FailureAction Rollback
```
You can monitor the progress of the upgrade on Service Fabric Explorer, or you can run the following PowerShell command:
```
Get-ServiceFabricClusterUpgrade
```
If the cluster health policies aren't met, the upgrade is rolled back. To specify custom health policies for the Start-ServiceFabricClusterUpgrade command, see the documentation for Start-ServiceFabricClusterUpgrade.

After you fix the issues that resulted in the rollback, initiate the upgrade again by following the same steps as previously described.
