Method Details

getExpression

@Stability(Stable)
@Nullable
default String getExpression()

A cluster query language expression to apply to the constraint.

You cannot specify an expression if the constraint type is distinctInstance . To learn more, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

getType

@Stability(Stable)
@Nullable
default String getType()

The type of constraint.

Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

builder

@Stability(Stable)
static CfnPipe.PlacementConstraintProperty.Builder builder()

Returns:

a CfnPipe.PlacementConstraintProperty.Builder of CfnPipe.PlacementConstraintProperty
