fluent/fluent-operator

Fluent Operator is a Kubernetes operator that facilitates the management of Fluent Bit and Fluentd in Kubernetes clusters.

The operator addresses the complexity of deploying and configuring log collection infrastructure in Kubernetes by automating the lifecycle management of both Fluent Bit DaemonSets and Fluentd StatefulSets. It allows operators to define logging pipelines declaratively using Kubernetes custom resources, selecting input, filter, and output plugins via labels. The tool supports dynamic configuration reloading, enabling updates to logging pipelines without requiring pod restarts, and provides multi-tenant log isolation capabilities through Fluentd's label-router plugin.

Teams should adopt this operator when they need flexible, Kubernetes-native log collection that can adapt to changing requirements without service disruption. It suits organizations running Kubernetes who want to leverage either Fluent Bit for lightweight edge collection or Fluentd for more complex processing, or both in a coordinated pipeline. The operator's pluggable architecture allows deploying these components separately based on specific needs, making it suitable for diverse logging architectures from simple single-destination setups to complex multi-tenant environments.

The project maintains active development with regular contributions addressing both new features and community-reported issues. The codebase demonstrates consistent quality standards and welcomes new contributors through clearly marked entry points. The project sustains an engaged community across multiple communication channels, indicating ongoing investment in supporting users and evolving the tool based on real-world logging requirements.
