Docker 部署的一个问题，求大神解惑
資深大佬 : ilaipi 58
问题是这样的，
我在服务器上跑了一个 Kafka，是跑的 wurstmeister/kafka 镜像，使用的默认网络。配置：
kafka: image: wurstmeister/kafka container_name: kafka environment: - KAFKA_ADVERTISED_PORT=port - KAFKA_ADVERTISED_HOST_NAME=公网 ip - KAFKA_ZOOKEEPER_CONNECT=本机内网 ip:zookeeper port - KAFKA_LOG_RETENTION_HOURS=4 - KAFKA_LOG_RETENTION_BYTES=1000000000 ports: - port:9092 然后在同一台服务器，使用 docker run 命令，启动了另外一个容器，使用的是 node-alpine 镜像，内部通过 kafka-node 库连接 kafka，怎么都连不上。
启动 node 容器后，进入容器，telnet 命令可以连上 Kafka 容器的端口。
在本机，不在容器内部，同一个连接（公网 ip：port ）可以正常连上 Kafka。
我在本机装了 Conduktor 这个 Kafka 客户端，也能连上 Kafka，可以正常收发消息。
有什么思路吗？谢谢！
启动 kafka，然后启动 node，看 node 镜像的日志就会卡住。然后 stop Kafka，node 这边就会报错：
