NAME

Paws::ECS::PlacementConstraint

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ECS::PlacementConstraint object:

  $service_obj->Method(Att1 => { Expression => $value, ..., Type => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ECS::PlacementConstraint object:

  $result = $service_obj->Method(...);
  $result->Att1->Expression

DESCRIPTION

An object representing a constraint on task placement. For more information, see Task Placement Constraints (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-placement-constraints.html) in the Amazon Elastic Container Service Developer Guide.

If you are using the Fargate launch type, task placement constraints are not supported.

ATTRIBUTES

Expression => Str

A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is "distinctInstance". For more information, see Cluster Query Language (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/cluster-query-language.html) in the Amazon Elastic Container Service Developer Guide.

Type => Str

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.
