Kafka在码头集装箱里工作得很好。我可以用 docker exec -it [container name] [kafkascript] 并成功地创建主题、生成/使用消息，但当我尝试从docker容器外部使用本地kafka脚本时，我只能创建和列出主题。生成和使用消息会引发错误：

我使用的是spotify/docker-kafka，但我将其升级到了0.10.0.0，并使用了jshark的一些建议来设置advised.listeners。我在mac电脑上跑步。我创造了一个叫Kafka的 Docker 机器。这是我的docker跑步：

docker run -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=`docker-machine ip kafka` --env ADVERTISED_PORT=9092 kafka

这是我的文件：
