Directory-based data distribution is an enhancement of the User-defined data distribution method, so the shard catalog is configured with the user-defined data distribution option.

GDSCTL> create shardcatalog -database catalog_connect_string
 -user mysdbadmin/mysdbadmin_password -sharding user
 -protectmode maxperformance 

More details about creating a shard catalog, including specifying the shard catalog Connect String and connecting to the shard catalog can be found in Create the Shard Catalog.
