Assume a deployment A, that has pod A1, A2, A3
Service is service-A which is associated with the deployment
Service endpoint : http://service-A..svc.cluster.local:8282/healthz

A rest get call to service endpoint returns 200 ok if atleast one pod is up and running + ready

Question :

can the rest get call to service endpoint return 200 ok ONLY IF ALL pods are up and running + ready. It should not return OK even if one pod is down

Is there any setting for that?

This is not something k8s can answer. That’s an application level problem - “down” can mean lots of things and k8s probes can only do so much.
