I remember seeing documentation on this a while ago, but I can't seem to find any documentation from nginx-ingress that talks about how nginx-ingress uses readinessprobe or livenessprobe.

I was looking into this because if I have a pod with 3 containers, if 1 container wasn't running, nginx-ingress stopped serving traffic. I actually want to continue serving traffic if a certain container is still running, not all 3 running necessarily

Do you know or have any documentation on how nginx-ingress actually does its readiness/liveness checks?
