Pushing K8s Cluster Logs to S3 Bucket using Fluentd

Learn how to set up a cost-effective Kubernetes logging pipeline using Fluent-bit and Fluentd with Helm charts. The solution combines short-term log storage in Elasticsearch (1-month retention) with long-term archiving in AWS S3 (6-month retention) to optimize costs. Fluent-bit acts as a lightweight log collector on Kubernetes nodes, while Fluentd aggregates and forwards logs to multiple destinations. The guide includes complete Helm configuration files and deployment commands for both components, plus best practices for secure log transfer, resource management, and retention policies.
