Description

Image Image Currently, we only support the `requiredDuringSchedulingIgnoredDuringExecution` scheduling strategy. Could we consider supporting the `preferredDuringSchedulingIgnoredDuringExecution` strategy to allow the runner Pod and the workflow Pod to be scheduled onto different nodes?

Research direction

Start by locating the Pod and Job handling that currently supports requiredDuringSchedulingIgnoredDuringExecution. Trace how scheduling constraints are built for the runner Pod and workflow Pod, then determine the changes needed to accept preferredDuringSchedulingIgnoredDuringExecution. Done means the preferred strategy is supported and allows those Pods to be scheduled onto different nodes; no file or test is named in the issue.
