我已经配置了一个fluentd sidecar容器来将日志发送到kafka
这是我的fluent.conf文件:

<source>
@type forward
bind 127.0.0.1
port 24224
</source>

<match log.default>
@type kafka2

# list of seed brokers
brokers node1:9092, node2:9092, node3:9092
use_event_time true

# buffer settings
buffer_type file
buffer_path /var/log/td-agent/buffer/kafka
flush_interval 3s

# topic settings
default_topic app_logs

# data type settings
<format>
@type json
</format>

# producer settings
max_send_retries 1
required_acks -1

#deubg log
@log_level debug
</match>
可从运行 fluentd sidecar容器的Pod到达代理主机。
但是,sidecar容器无法连接到代理。它返回以下日志:

如何摆脱这个问题?从代理节点那边可能会出问题吗?

最佳答案

在流畅的主机上,尝试使用https://github.com/edenhill/kafkacat调试Kafka的连接/访问。我确定这是网络/防火墙问题,而不是流利的问题。
