我有一个融合的kafka设置和docker-compose.yml文件
我已经编辑了文件并将ports选项添加到docker compose文件中，以便可以在主机外部访问它们。

我已经运行了以下命令：
docker-compose up --no-start
docker-compose start zookeeper-1
docker-compose start zookeeper-2
docker-compose start zookeeper-3
docker-compose run -d --service-ports kafka-1
docker-compose run -d --service-ports kafka-2
docker-compose run -d --service-ports kafka-3
zookeeper-1,2,3启动，但kafka-1失败，退出代码为0。
当我执行docker-compose start kafka-1时，端口没有暴露，但是服务已启动。
以上命令的输出：
docker ps

这里的问题是必须将KAFKA_ADVERTISED_LISTENERS中的IP地址设置为主机的IP地址。这样，当您在另一台计算机上运行它时，该计算机将能够使用IP地址访问kafka。
KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://10.1.1.1:39092
@Ntwobike指出的下一点是删除-p选项。并非不需要，但设置了--net=host选项时，它是多余的。
最重要，是检查防火墙。检查 iptables 规则并将其更改为FORWARD ACCEPT（在我的情况下，因为我是开发主机，所以已经这样做了。）
如果您使用的是CentOS或RHEL，则可以尝试停止firewalld并检查是否是引起问题的防火墙。
systemctl stop firewalld
对于其他人，这是ufw（Ubuntu，薄荷）
systemctl stop ufw
或者，您也可以执行iptables -F，但在此之前请确保您使用
iptables-save > /home/iptables_rules_bak
然后刷新规则后，您可以
iptables -P FORWARD ACCEPT

如果您查看Confluent撰写的all-in-one撰写示例，那么将正确设置所有内容，以便从各个方向访问代理，而不使用network: host“ hacks”（仅在Linux上有效）< / p>
引用
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://broker:9092,PLAINTEXT_HOST://localhost:29092
在Docker网络外部，您可以通过端口29092进行连接，但在内部则为9092
更重要的是，Zookeeper连接字符串实际上应该指向彼此，而不是localhost
我还要指出的是，在一台计算机上的多个代理没有很多好处，并且如果您想要持久的数据（如果重新启动计算机或Docker，不要丢失所有内容），那么您将需要大量坐骑
