我的docker-compose正在运行，但我无法从主机访问

Question

这是我的docker-compose。yml文件

networks:
elk:
driver: bridge
volumes:
elasticsearch:

这里是我的logstash.conf文件:

input {
kafka {
bootstrap_servers => "kafka:9092"
topics => "results"
codec => json { charset => "UTF-8" }
}
}
filter {
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
user => "elastic"
password => "changeme"
ecs_compatibility => disabled
}
}

我可以发送消息到结果主题，但我也不能在容器内看到此消息，也不能在容器内产生任何消息。这里出了什么问题?如果我可以建立连接，这个消息将通过logstash吗?

Answer 1

KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092

如果你只通告localhost, Docker网络中的Kafka客户端无法到达你的broker。

另外，我不确定Strimzi图像甚至使用了这些变量- source

你可以使用confluentinc/cp-kafka镜像，在这篇文章中讨论的稍微修改这些变量，或者如果你有反对的东西，你可以使用Bitnami或wurstmeister容器，它们每个都有自己的单独的环境变量用于这些设置
