control the length of a random string - Resource Orchestration Service

You can set AssociationProperty to AutoCompleteInput in Resource Orchestration Service (ROS) to automatically generate a random string.

You can set AssociationProperty in the RandomName parameter of the Parameters section of a template to AutoCompleteInput to generate a random string. Then, you can specify the Length, Prefix, and CharacterClasses properties in AssociationPropertyMetadata to control the length of the random string.
