For troubleshooting purpose, I would like to find out if any existing service is pointing to the specific pod, or at least ReplicaSet/Deployment, that I am currently working on.
Is this possible with kubectl? If yes, how so?
There is no way with kubectl to find out however you can get an idea of service and pod by filtering with the label
kubectl get pod -l app.kubernetes.io/instance=example-service
kubectl get svc -l app.kubernetes.io/instance=example-servicehowever, you can use tools like https://www.jaegertracing.io/ for tracing
Or Kaili dashboard with istio depends on your stack
