Kubernetes metadata is the descriptive portion of an object definition. It identifies and organizes resources through fields such as names and labels, while labels support selection by services, ReplicaSets, and deployments. section 3.3.3
Operational systems can also attach custom metadata to observability traces. Query analysis, retrieval success, context use, and user-session information add business context to otherwise technical LLM metrics. section 12.4.3
Metadata in a pod definition
A pod declares its identity under metadata: name: joker. A ReplicaSet or deployment can additionally define labels such as app: fast-api, then match those labels when managing pods. section 3.3.3
