kubernetes - 如何基于StatefulSets中的序数索引将args传递给Pod？

是否可以根据StatefulSets中的序数索引将不同的args传递给Pod？在StatefulSets文档中找不到答案。谢谢!

推荐方式，请参见https://kubernetes.io/docs/tasks/run-application/run-replicated-stateful-application/#statefulset

# Generate server-id from pod ordinal index.

[[ `hostname` =~ -([0-9]+)$ ]] || exit 1
ordinal=${BASH_REMATCH[1]}

# ${ordinal} now holds the replica number

server-id=$((100 + $ordinal))

# Copy appropriate conf.d files from config-map to emptyDir.
if [[ $ordinal -eq 0 ]]; then
  # do something
else
  # do something else
fi
