Spring Cloud Data Flow java DSL: get logs for stream components - spring-cloud-dataflow

Question

I'm using SCDF 2.5.1 deployed locally via docker-compose and my software sends commands to the SCDF server via the java DSL.
Let's say I create a stream such that
file > :queue
:queue > ftp
where file and ftp are docker deployed apps.
My question is, how can I get the logs for file and ftp?
So far the closest thing I've come up with is
Map<String, String> attributes = scdf.runtimeOperations().streamStatus(streamName).getContent()
.stream().flatMap(stream -> stream.getApplications().getContent().stream()
.filter(app -> app.getName().equals(appName))
.flatMap(appStatus -> appStatus.getInstances().getContent().stream()
.map(AppInstanceStatusResource::getAttributes)))
.findFirst().orElse(Collections.emptyMap());
String logLocation = attributes.get("stdout")
and then mounting logLocation and reading it as a file.
Is there a more elegant solution?

The Java DSL (and subsequently the SCDF REST client) doesn't have log retrieval operation as part of it's REST operations. There is an REST endpoint you can hit the SCDF server to get the logs of stream.
