简介

GoFlow2 NetFlow/sFlow/IPFIX 采集器镜像，接收路由器导出的流记录并序列化为 Kafka/stdout，用于网络流量分析与计费。

详细介绍

netsampler/goflow2 监听 UDP 2055 等端口接收 NetFlow v5/v9、sFlow 与 IPFIX，解码后输出 JSON 或写入 Kafka topic。典型部署在 SP/数据中心边界，与 Elasticsearch 或 ClickHouse 下游配合做 Top-N 与 DDoS 检测。镜像无状态、CPU 随 flow rate 增长；Kubernetes 中需 hostNetwork 或 NodePort 接收 UDP，Deployment 副本按节点分散采集。

快速启动

docker run -d --name goflow2 \
  -p 2055:2055/udp \
  docker.io/netsampler/goflow2:latest \
  -transport=file -transport.file=/dev/stdout

推荐实践

docker run -d --name goflow2 \
  --restart unless-stopped \
  -p 2055:2055/udp -p 6343:6343/udp \
  -e KAFKA_BROKERS=kafka.internal:9092 \
  docker.io/netsampler/goflow2:v2.2.0 \
  -transport=kafka -transport.kafka.brokers=kafka.internal:9092 \
  -transport.kafka.topic=netflow

核心参数说明

  • -p 2055:2055/udp — NetFlow/IPFIX 默认端口
  • -p 6343:6343/udp — sFlow 默认端口
  • -transport=kafka — 输出至 Kafka topic
  • -transport.kafka.topic — 下游消费 topic 名
  • --restart unless-stopped — 采集器持续运行
  • 固定 tag — 解码器版本 pin

            - -transport.kafka.topic=netflow
          ports:
            - containerPort: 2055
              protocol: UDP

边界节点用 DaemonSet + hostNetwork 收 UDP；Kafka broker 地址与 topic 按集群网络调整，高 flow 场景提高 CPU requests。
