Description

The Update-ServiceFabricService cmdlet updates properties of a running Service Fabric service. The set of properties that can be updated are a subset of the properties that were specified at the time of creating the service (using New-ServiceFabricService or New-ServiceFabricServiceFromTemplate). You can get current properties of your service using Get-ServiceFabricServiceDescription.

Please note that updating the properties of a running service is different than upgrading your service using Start-ServiceFabricApplicationUpgrade.Upgrading your service (i.e. application) is a long running background task that involves moving your application, from one version to another, one upgrade domain at a time. Please see Service Fabric Application Upgrade for more details.

Before you perform any operation on a Service Fabric cluster, establish a connection to the cluster by using the Connect-ServiceFabricCluster cmdlet.

Examples

Example 1: Update a stateful service

PS C:\> Update-ServiceFabricService -Stateful fabric:/myapp/test -MinReplicaSetSize 3 -TargetReplicaSetSize 5

This command updates the MinReplicaSetSize and TargetReplicaSetSize of a running Fabric Service to three (3) and five (5).

Example 2: Update a stateless service

PS C:\> Update-ServiceFabricService -Stateless fabric:/myapp/test -InstanceCount -1

This command updates the instance count of a running Fabric Service to a value of -1.

Example 3: Update placement constraints

PS C:\> Update-ServiceabricService -Stateless -ServiceName fabric:/myapp/test -PlacementConstraints "NodeName!=NodeBar"

This command updates the placement constraints.

Example 4: Update default load metrics

PS C:\> Update-ServiceFabricService -Stateless -ServiceName fabric:/myapp/test -Metric @("CPU,High,10")
PS C:\> Update-ServiceFabricService -Stateful -ServiceName fabric:/myapp/test -Metric @("CPU,High,10,1")

The first command updates the default load metrics for a stateless service.

The second command updates the default load metrics for a stateful service.

Example 5: Update placement policy

PS C:\> Update-ServiceFabricService -Stateful -ServiceName fabric:/myapp/test -PlacementPolicy @("InvalidDomain,fd:/dc2/rack2")

This command updates the placement policy.

Example 6: Update service correlation

PS C:\> Update-ServiceFabricService -Stateful -ServiceName fabric:/myapp/test -Correlation @("fabric:/app/test2,AlignedAffinity")

This command updates the service correlation.

Example 7: Update service DNS name

PS C:\> Update-ServiceFabricService -Stateful -ServiceName fabric:/myapp/test -ServiceDnsName stateful.dns
PS C:\> Update-ServiceFabricService -Stateless -ServiceName fabric:/myapp/test -ServiceDnsName stateless.dns

This command updates the service DNS name of a service. Note : If the updated DNS name has already been queried on the cluster or the updating service already had a DNS name, DNS service should be restarted after the update to invalidate the cache.

Accept wildcard characters:	False

-DefaultMoveCost

Specifies the updated default move cost that replicas have when they are created. The acceptable values for this parameter are:

• Zero
• Low
• Medium
• High

For more details about move cost, see Service movement cost for influencing Cluster Resource Manager choices.

Type:	String
Accepted values:	Zero, Low, Medium, High, VeryHigh
Position:	Named
Default value:	None
Accept pipeline input:	False

-DropSourceReplicaOnMove

Enables source Secondary replicas to be dropped before new Secondary replicas finish the build.

Type:	Boolean
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

-Force

Forces the command to run without asking for user confirmation.

Type:	SwitchParameter
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

-InstanceCloseDelayDuration

Specifies the duration in seconds, to wait before a stateless instance which is impacted by application upgrade is closed, to allow the active requests to drain gracefully. This wait duration is effective only for the instances of those stateless services which have a non-zero value configured for the InstanceCloseDelayDuration, and will override the pre-configured value. See InstanceCloseDelayDuration for details. Do not specify this parameter for stateful services.

Type:	TimeSpan
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

-InstanceCount

Specifies the updated number of instances for the Service Fabric stateless service. Do not specify this parameter for stateful services.

Type:	Int32
Position:	Named
Default value:	None

-InstanceLifecycleDescription

Lifecycle description of instances belonging to this service. If some configuration in this section is not specified, the default value is taken from the cluster parameter of the same name (if existing).

Type:	InstanceLifecycleDescription
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

-InstanceRestartWaitDuration

When a stateless instance goes down, this timer starts. When it expires Service Fabric will create a new instance on any node in the cluster. This configuration is to reduce unnecessary creation of a new instance in situations where the instance going down is likely to recover in a short time. For example, during an upgrade. The default value is 0, which indicates that when stateless instance goes down, Service Fabric will immediately start building its replacement.

Type:	TimeSpan
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False

Accept wildcard characters:	False

-MinInstancePercentage

Specifies the updated minimum percentage of InstanceCount of a stateless service partition. See MinInstancePercentage (in New-ServiceFabricService) for details. Do not specify this parameter for stateful services.
