Eventrouter is a Kubernetes service that forwards cluster events to a specified sink.
The tool solves the problem of event persistence and analysis in Kubernetes clusters. By default, Kubernetes only retains events for a limited time, making it difficult to perform long-term behavioral analysis or debugging of workloads. Eventrouter actively watches the event resource in the Kubernetes system and pushes those events to a user-specified sink, enabling operators to forward events to external systems for archiving, machine learning, introspection, or other purposes. The service is designed to be relatively low overhead and supports configuration of multiple sinks.
Eventrouter suits operators who need to retain and analyze Kubernetes events beyond the cluster's default retention window. It works well for teams using existing EFK (Elasticsearch, Fluentd, Kibana) stacks, as it outputs wrapped JSON objects designed for easy indexing in Elasticsearch. The tool is appropriate for any cluster where long-term event analysis, debugging, or integration with external monitoring and logging systems is required. The project explicitly does not provide query capabilities or serve as a storage layer; those responsibilities belong to the sink system receiving the forwarded events.
The project maintains a straightforward, focused codebase written in Go. Development activity shows consistent engagement with the core functionality of event watching and forwarding, with attention to supporting multiple sink configurations and maintaining low operational overhead.
