maven - Kafka Docker和端口转发从9092到9093

Question

我已经通过maven docker plugin https://dmp.fabric8.io/配置了Kafka + ZooKeeper:

<image>
    <name>wurstmeister/zookeeper:latest</name>
    <alias>zookeeper</alias>
    <run>
        <ports>
            <port>2181:2181</port>
        </ports>
    </run>
</image>

<image>
    <name>wurstmeister/kafka:1.0.0</name>
    <alias>kafka</alias>
    <run>
        <ports>
            <port>9092:9092</port>
        </ports>
        <links>
            <link>zookeeper:zookeeper</link>
        </links>
        <env>
            <KAFKA_ADVERTISED_HOST_NAME>127.0.0.1</KAFKA_ADVERTISED_HOST_NAME>
            <KAFKA_ZOOKEEPER_CONNECT>zookeeper:2181</KAFKA_ZOOKEEPER_CONNECT>
        </env>
    </run>
</image>

在此配置下，一切正常。

现在，我需要将Kafka端口(主机系统的转发端口)从 9092更改为 9093。

在我的Spring Boot应用程序的 application.properties中，添加了以下行:

spring.kafka.bootstrap-servers=127.0.0.1:9093

并将Kafka图片的配置更改为:

<image>
    <name>wurstmeister/kafka:1.0.0</name>
    <alias>kafka</alias>
    <run>
        <ports>
            <port>9093:9092</port>
        </ports>
        <links>
            <link>zookeeper:zookeeper</link>
        </links>
        <env>
            <KAFKA_ADVERTISED_HOST_NAME>127.0.0.1</KAFKA_ADVERTISED_HOST_NAME>
            <KAFKA_ZOOKEEPER_CONNECT>zookeeper:2181</KAFKA_ZOOKEEPER_CONNECT>
        </env>
    </run>
</image>

并遇到以下错误:

我在做什么错以及如何解决？

为什么NetworkClient仍尝试连接到 9092？

2017-11-22 18:18:16.492 DEBUG 17532 --- [ad | producer-1] org.apache.kafka.clients.NetworkClient   : Initiating connection to node 1001 at 127.0.0.1:9092.

更新了

我还尝试了以下 env属性:

<env>
    <KAFKA_ADVERTISED_HOST_NAME>127.0.0.1</KAFKA_ADVERTISED_HOST_NAME>
    <KAFKA_ADVERTISED_PORT>9093</KAFKA_ADVERTISED_PORT>
    <KAFKA_ZOOKEEPER_CONNECT>zookeeper:2181</KAFKA_ZOOKEEPER_CONNECT>
</env>

这样我有另一个 LEADER_NOT_AVAILABLE错误:
