Constructor

ServiceUpdateDescription(*, flags: Optional[str] = None, placement_constraints: Optional[str] = None, correlation_scheme=None, load_metrics=None, service_placement_policies=None, default_move_cost=None, scaling_policies=None, service_dns_name: Optional[str] = None, tags_for_placement=None, tags_for_running=None, **kwargs)

Parameters

flags: str

Required

Flags indicating whether other properties are set. Each of the associated properties corresponds to a flag, specified below, which, if set, indicate that the property is specified. This property can be a combination of those flags obtained using bitwise 'OR' operator. For example, if the provided value is 6 then the flags for ReplicaRestartWaitDuration (2) and QuorumLossWaitDuration (4) are set.

None - Does not indicate any other properties are set. The value is zero.
TargetReplicaSetSize/InstanceCount - Indicates whether the TargetReplicaSetSize property (for Stateful services) or the InstanceCount property (for Stateless services) is set. The value is 1.
ReplicaRestartWaitDuration - Indicates the ReplicaRestartWaitDuration property is set. The value is 2.
QuorumLossWaitDuration - Indicates the QuorumLossWaitDuration property is set. The value is 4.
StandByReplicaKeepDuration - Indicates the StandByReplicaKeepDuration property is set. The value is 8.
MinReplicaSetSize - Indicates the MinReplicaSetSize property is set. The value is 16.
PlacementConstraints - Indicates the PlacementConstraints property is set. The value is 32.
PlacementPolicyList - Indicates the ServicePlacementPolicies property is set. The value is 64.
Correlation - Indicates the CorrelationScheme property is set. The value is 128.
Metrics - Indicates the ServiceLoadMetrics property is set. The value is

DefaultMoveCost - Indicates the DefaultMoveCost property is set. The value is 512.
ScalingPolicy - Indicates the ScalingPolicies property is set. The value is 1024.
ServicePlacementTimeLimit - Indicates the ServicePlacementTimeLimit property is set. The value is 2048.
MinInstanceCount - Indicates the MinInstanceCount property is set. The value is 4096.
MinInstancePercentage - Indicates the MinInstancePercentage property is set. The value is 8192.
InstanceCloseDelayDuration - Indicates the InstanceCloseDelayDuration property is set. The value is 16384.
InstanceRestartWaitDuration - Indicates the InstanceCloseDelayDuration property is set. The value is 32768.

TagsForRunning - Indicates the TagsForRunning property is set. The value is 2097152.

placement_constraints: str

Required

The placement constraints as a string. Placement constraints are boolean expressions on node properties and allow for restricting a service to particular nodes based on the service requirements. For example, to place a service on nodes where NodeType is blue specify the following: "NodeColor == blue)".
