How to pass args to pods based on Ordinal Index in StatefulSets?

Question

Is it possible to pass different args to pods based on their ordinal index in StatefulSets? Didn\'t find the answer on the StatefulSets documentation. Thanks!

In case you want to track the progress of this, the ticket in question for this feature is here: https://github.com/kubernetes/kubernetes/issues/30427

The proposal involves putting the ordinal as a label on the pod and then using the downward api to pull that out into an environment variable or something.
