为什么我不能访问基于Docker的zookeeper端口
在OS X上，我成功启动了kafka docker镜像，但似乎无法在本地主机上访问它
➜ ~ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 1f931da3d661 wurstmeister/zookeeper:3.4.6 "/bin/sh -c '/usr/..."

docker-compose -f src/main/docker/kafka.yml up -d
当我使用
./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 java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:361) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1141)
我怎样才能访问2181端口

您是否尝试过使用主机networking？ https://docs.confluent.io/current/cp-docker-images/docs/quickstart.html#zookeeper
这看起来会简化和解决这个问题。 我还build议查看这些图片，而不是看起来像您正在使用的自定义的图片，因为这些图片正在为人们的生产运行，所以他们被称为工作得很好。
