我正在尝试从一个Logstash Docker容器连接到一个Kafka Docker容器,但我总是收到以下信息:
我的docker-compose.yml文件是:
我的logstash.conf文件如下:
Connection to node 0 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.
我的docker-compose.yml文件是:

我的logstash.conf文件如下:

## Add your filters / logstash plugins configuration here
output {
elasticsearch {
hosts => "elasticsearch:9200"
user => "elastic"

}
}
我的所有容器都正常运行,我可以将消息发送到容器外的Kafka主题中。
