我需要一个用于测试的小型 kafka 设置。

我是 kafka 的新手，我找不到连接到我在 docker 容器中设置的 kafka 的方法：

我尝试使用https://hub.docker.com/r/spotify/kafka/，这是一个包含zookeeper和kafka的容器，但我不知道kafka的ip是什么：

docker run -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=`docker-machine ip \`docker-machine active\`` --env ADVERTISED_PORT=9092 spotify/kafka

我正在使用 kafka-ui 连接到它。我正在尝试使用：

zookeeper: localhost:2181   <--- working

kafka: localhost:9092 <--- ERROR: "The broker [localhost:9092] is reachable
 but Kafka can't connect. ensure you have access to the *advertised listeners* 
 of the cluster and the proper authorizations."

【问题讨论】：

你在使用 Docker 工具箱吗？ docker-machine ip 命令中的 docker-machine ip 命令将为您提供访问 Kafka 或任何其他容器的 IP 地址。如果没有，那么您根本不需要运行任何 docker-machine 命令。

【解决方案1】：

不再维护 Spotify 容器。

我建议您遵循 Confluent Docker 快速入门指南或至少使用 Docker Compose 而不是任何一体式 Kafka+ZooKeeper 映像

我还会向你指出蓝色的帮助内容，上面写着“还是 Docker？”

但是我不知道kafka的ip是什么：

它和 Zookeeper 的 IP 相同，因为你在这里只使用一个主机

看来您使用的是 Linux，所以不清楚为什么需要 Docker Machine
