If a Pod crashes, does the Service send traffic to it?

No. Kubernetes maintains 'Endpoints' for every Service. If a Pod fails its health checks (Readiness Probe), it is instantly removed from the Service's Endpoints list, ensuring no traffic is sent to a dead pod.

How do I test a ClusterIP service from my laptop?
