Current pod logs are empty after a crash loop; where should we look next?

A fictional container starts and exits repeatedly. The current log view often contains only startup text, and the useful error seems to disappear after restart. The pod is already scheduled. How can the team collect evidence from the failed container instance before changing memory limits?

Inspect the pod’s container state, last termination reason and restart count. Use kubectl logs with the container name, namespace and --previous option to request output from the previous container instance where available. Bound the log output and redact secrets before sharing it.

Compare the exit information with the application error. An invalid configuration, an ordinary process exit and a memory termination call for different fixes. Increasing memory without evidence may hide nothing and consume more capacity. Apply one supported correction and watch the controller’s rollout and new termination state.

If the termination reason shows a configuration error, should we still raise the memory limit as a precaution?

Fix and verify the configuration cause first. A resource change should follow evidence of resource pressure, not be bundled into every crash-loop response.

Check that you selected the failing container in a multi-container pod. Logs from a healthy sidecar can make the investigation appear inconsistent.
