Question

How to set default Data source name (say MyDS). Swarm is always taking "ExampleDS" as defaultDatasource.

with earlier versions it used to be something like this

container.fraction(new PostgreSQLJPAFraction()
        .inhibitDefaultDatasource()
        .defaultDatasource("jboss/datasources/MyDS")

Answer 1

You can set the datasource name to be used with swarm.ds.property variable via -D on command line or with a yaml configuration file.
