+Database containers can create an Ebean DatabaseBuilder and also a DataSourceBuilder.
+For full programmatic test setup like:
+```java
+  PostgresContainer container = PostgresContainer.builder("17")
+    .dbName("my_app1") // this needs to be unique, not clash with other projects
+    .start();
+
+  DatabaseBuilder ebeanBuilder = container.ebean().builder();
+  Database ebeanDatabase = ebeanBuilder.build();

 Some containers like Redis, Localstack, LocalDynamoDB, ElasticSearch, ClickHouse do not have a concept
 like "database" and instead multiple projects share a global namespace.
