How to setup topologySpreadConstraints config

[hxndg]

I' m writing a workflow template for convert data tasks, which on a argo 3.7.1 server and kubernetes 1.30.1 groups.

I want the workflow pod to distribute on nodes evenly, so add topologySpreadConstraints into a workflow tempale, which report a strict decoding error.

Should I patch it into podSpecPatch to make it work? Or should I just use k8s affinity config to let the workflow distribute evenly?

Example below

      topologySpreadConstraints:
        - maxSkew: 1
          topologyKey: kubernetes.io/hostname
          whenUnsatisfiable: ScheduleAnyway
          labelSelector:
            matchLabels:
              app: some_work

Yes, podSpecPatch is sufficient for your needs.
