什么是fluent-bit？

Fluent Bit 是一款开源的轻量级日志处理器与转发器，专为嵌入式系统、容器化环境及分布式架构设计。其核心功能包括日志收集、过滤、聚合和传输，支持多种输入源（如文件、系统日志、HTTP接口）和输出目标（如Elasticsearch、Kafka、云存储服务）

工作流程

日志通过数据管道从数据源发送到目的地，一个数据管道可以由input，paser，filter，buffer，routing，output等组成。

input插件：用于从数据源抽取数据，一个数据管道中可以包含多个input

parser组件：负责将input抽取的非结构化数据转化为标准的结构化数据，每个input均可以定义自己的parser

filter插件：负责对格式化数据进行过滤和修改。一个数据管道中可以包含多个filter，多个filter执行顺序与配置文件中的顺序一致

buffer组件：用户缓存经过filter处理的数据，默认情况下buffer把input插件的数据缓存到内存中，直到路由传递到output为止

routing组件：将buffer中缓存的数据路由到不同的output

output插件：负责将数据发送到不同的目的地，一个数据管道中可以包含多个output

测试：

在生产者主机上发布消息：

[root@k8s-master bin]#  echo "test message" | /home/kafaka-zookeeper/kafka_2.12-3.8.0/bin/kafka-console-producer.sh   --broker-list 192.168.9.128:9092,192.168.9.129:9092,192.168.9.130:9092   --topic k8s-logs

在消费者主机进行查看：

/home/kafaka-zookeeper/kafka_2.12-3.8.0/bin/kafka-console-consumer.sh \
--bootstrap-server 192.168.9.128:9092,192.168.9.129:9092,192.168.9.130:9092 \
--topic k8s-logs \
--from-beginning

可以看到容器的日志被输出到kafka当中：
