See, for example, the thread at https://forum.nginx.org/read.php?2,290205
In short: stock nginx does not care if the upstream service (the pod)
is running or not; but it does care that whatever hostname you use in the
"upstream" section resolves to an IP address at nginx-start time.
That thread does list a few possible ways of approaching a solution;
maybe one will work for you?

"exist" should not matter.
"can resolve dns" does matter.
Good luck with it,
