antrea/flow-aggregator repository overview

Antrea is a Kubernetes network plugin that provides network connectivity and security features for Pod workloads. Considering the scale and dynamism of Kubernetes workloads in a cluster, Network Flow Visibility helps in the management and configuration of Kubernetes resources such as Network Policy, Services, Pods etc., and thereby provides opportunities to enhance the performance and security aspects of Pod workloads.

Each instance of the Antrea Agent can export flow information, via the IPFIX protocol. The Flow Aggregator is meant to collect that information, enhance it, before exporting it to an external flow collector.

The Flow Aggregator is meant to be run as a single-replica Deployment in a K8s cluster, alongside the other Antrea components (Agents and Controller).
