Module Values.PlacementConstraintSource

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide. If you're using the Fargate launch type, task placement constraints aren't supported.

Sourcetype nonrec t = {
  1. type_ : PlacementConstraintType.t option;
    (*

    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.

    *)
  2. expression : String_.t option;
    (*

    A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.
