Scale the pod on the same node where EBS is attached

Question

I want to scale the pods in the same worker node where already one EBS volume associated with pod is attached. How can I achieve it?

Thanks

Answer 1

you can configure PodAffinity to schedule new pods only on the same node that it is already scheduled (obviously not in case of first one).
