Announcing Amazon Web Services for Fluent Bit 3.0.0 based on Fluent Bit 4.1.1
Amazon Web Services for Fluent Bit announces version 3.0.0, based on Fluent Bit version 4.1.1 and Amazon Linux 2023. Container logging using Amazon Web Services for Fluent Bit is now more performant and more feature-rich for customers, including those using Amazon Elastic Container Services (Amazon ECS) and Amazon Elastic Kubernetes Service (Amazon EKS).
Amazon Web Services for Fluent Bit enables Amazon ECS and Amazon EKS customers to collect, process, and route container logs to destinations including Amazon CloudWatch Logs, Amazon Data Firehose, Amazon Kinesis Data Streams, and Amazon S3 without changing application code. Version 3.0.0 upgrades the Fluent Bit version to 4.1.1, and upgrades the base image to Amazon Linux 2023. These updates deliver access to the latest Fluent Bit features, significant performance improvements, and enhanced security. New features include native OpenTelemetry (OTel) support for ingesting and forwarding OTLP logs, metrics, and traces with Amazon SigV4 authentication—eliminating the need for additional sidecars. Performance improvements include faster JSON parsing, processing more logs per vCPU with lower latency. Security enhancements include TLS min version and cipher controls, which enforce your TLS policy on outputs for stronger protocol posture.
You can use Amazon Web Services for Fluent Bit 3.0.0 on both ECS and EKS. On ECS, update the FireLens log-router container image in your task definition to the 3.0.0 tag from the Amazon ECR Public Gallery. On EKS, upgrade by either updating the Helm release or setting the DaemonSet image to the 3.0.0 version.
The Amazon Web Services for Fluent Bit image is available in the Amazon ECR Public Gallery. You can also find it on GitHub. For more information, see the ECS FireLens developer guide, Amazon EKS on Fargate logging guide, and CloudWatch EKS add-on guide.
