A Kubernetes event records a noteworthy state change involving a resource. Events differ from container and component logs: they summarize transitions such as a pod moving from Pending to Running or from Running to failing, often exposing a reason and message useful for troubleshooting. section 8.2.1
Use events efficiently during cluster troubleshooting:
- List events across namespaces with kubectl get events -A; events are namespaced resources. section 8.2.1
- Filter out routine Normal messages with kubectl get events --field-selector type!=Normal -A to focus on warnings and information. section 8.2.1
- Treat events as short-lived evidence: they remain for one hour by default, and the API server's --event-ttl option can change retention. section 8.2.1
Finding a failing pod
Run kubectl get events -A and inspect the reason and message. A result such as Warning, BackOff, pod/brick, and “Back-off restarting failed container” points toward a repeatedly failing container; continue with logs and other cluster evidence. section 8.4
