How to Troubleshoot a Kubernetes Service That Sends Traffic to Unready Pods

Traffic can reach pods that are not ready if probes are absent or misconfigured, readiness gates are ignored, or a proxy uses a separate endpoint list. Users may see intermittent errors during startup.

What to check

Inspect readiness probes, EndpointSlices, pod conditions, rollout events, service mesh routing, and actual request logs. Check whether a pod becomes ready before dependencies are usable.

Recommended next step

Align readiness checks with user-serving capability and drain connections during termination. Verify service endpoints during a controlled rollout and monitor error rates.
