least_conn upstream configuration issue "host not found in upstream" with Kubernetes DNS

[kpirateone]

thanks for your prompt response,

i did read through this thread prior and it does relate to my understanding
of the issue.

it seems like we could

1) use ips instead of host names, not ideal due to the dynamic nature of the
ips
2) maintain an upstream configuration externally and use nginx reload to
modify the upstream as pods come online

scaling up, as stated in the referenced thread
(https://forum.nginx.org/read.php?2,290205) is not supported in stock
nginx.

there doesnt seem to be any way to use a least connected policy without
individually knowing all the hosts?  as in, there is no way to use least
connected over a headless service that returns multiple ips; we must need to
explicitly declare all known hosts?

i think i understand, thanks again
