SCDF Kubernetes scheduling with existing Kubernetes Cluster

We are working on a new deployment of SCDF in our Kubernetes environment. The new SCDF is supposed to schedule and run some Spring-batch containers.

We know that in order to do that, an application needs to be created with a path to the Docker Container, which then spins up a POD when the task is scheduled.

However, our requirement is that we need to point the application/task to an existing Kubernetes POD (containing the Spring-Batch containers).

So question is: Is this possible in SCDF? if so, how?

Know someone who can answer?
