关于kubesphere日志收集到kafka中的问题

still-L

huanggze 那能mount node /etc/hosts文件么？

huanggze

still-L 你看看官网的教程（下面说明那部分）能不能帮到你 https://kubesphere.com.cn/docs/v2.1/zh-CN/platform-settings/output-kafka/#%E7%AC%AC%E4%B8%80%E6%AD%A5%EF%BC%9A%E5%88%9B%E5%BB%BA-zookeeper–kafka-%E9%9B%86%E7%BE%A4

huanggze 感谢支持，我改成功了，我把fluentbit的ds配置改了，添加了本地的hosts文件。可以发送日志到kafka了。猜想数据流是这样的，kubesphere平台创建完成日志接收者之后，第一阶段去联系kafka创建topic 这个过程使用的IP通信，第二阶段往topic传输日志的时候使用的是kafka集群的hostname。嗯，这个思路是猜想的，目前看是这样的。

still-L 赞！可以把改后的 ds yaml 分享出来，供以后大家参考吗？
