EvidenceWhat to capture
Cluster event timelineShow the inputs, scope and decisions behind this record. The diagnosis uses cluster events rather than guessing from one failed request.
Recovery procedure with health checksInclude the evidence supporting your conclusion. Recovered replicas are ready and receive service traffic.

Restore a service after a node becomes unavailable

A small Kubernetes service loses capacity when a worker node becomes unavailable. You must explain scheduling, service endpoints and recovery.
