Under the Hood with Fluent Bit Operator: Kubernetes-native Log Processor
summary
Lightweight Fluent Bit (the 640 KB C binary with ~70 plugins) is deployed as a Kubernetes log pipeline managed by a Fluent Bit Operator that defines six CRDs, generates merged configs into a Secret, and mounts them into a DaemonSet per node where a small watcher triggers graceful restarts to apply changes. DigitalOcean App Platform and KubeSphere use it to aggregate, parse and forward logs to Elasticsearch/Kafka/S3; live demo shows config apply and logs appearing, so the operator-based system works end-to-end.
