Question

在OS X上我成功启动了kafka docker image，但似乎我无法在localhost上访问它

➜  ~ docker ps -a
CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS              PORTS                                                NAMES

我的泊坞窗文件在kafka.yml，并使用此命令启动：

docker-compose -f src/main/docker/kafka.yml up -d

当我使用

时

./mvnw

控制台是：

2017-09-15 17:05:46.433  WARN 15871 --- [localhost:2181)] org.apache.zookeeper.ClientCnxn          : Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

我如何访问2181端口

docker logs 8bc36bcf8fdf

java.lang.RuntimeException: A broker is already registered on the path /brokers/ids/1001. This probably indicates that you either have configured a brokerid that is already in use, or else you have shutdown this broker and restarted it faster than the zookeeper timeout so it appears to be re-registering.

您是否尝试过使用此示例中的主机网络？ https://docs.confluent.io/current/cp-docker-images/docs/quickstart.html#zookeeper

看起来它会简化并解决这个问题。我还建议您查看这些图片而不是您正在使用的自定义图片，因为这些图片正在为人们制作，因此他们知道效果很好。

为什么我不能访问基于docker的zookeeper端口
