Centralized Logging with Fluentd and ELK
Kubernetes logs are ephemeral by default. For production, use centralized logging solutions like:
- EFK: Elasticsearch + Fluentd + Kibana
 - Fluent Bit: Lightweight alternative to Fluentd
 - Loki: Grafana’s logging tool
 
How It Works:
- Fluentd collects logs from all nodes.
 - Logs are filtered and formatted.
 - They’re pushed to Elasticsearch (or Loki).
 - Visualize via Kibana or Grafana.
 
Pod Logging Command:
kubectl logs my-pod-name
