Spring cloud dataflow - Composite Task with external configuration

Question

I have a composite task with two cloud task ( AAA && BBB ). I want to pass the properties to AAA and BBB task from a directory. For example, the usage of "--spring.config.location=directory/" when launching the Spring boot application.

As per the documentation, i understand that we can pass properties using app.CompositeTaskName.taskname.prop1=val1. But, i want to load a bunch of configuration at launch. So, is there a way to launch the tasks with "spring.config.location" argument ?

Answer 1

I found the solution. I passed "--spring.config.location" in the task definition of my composite task.

task create myctr --definition "AAA --spring.config.location=/data/prop/ '*'->BBB"

I launched the composite task "myctr" and it referred the property files from the "/data/prop/" directory.
