I have configured Kafka + ZooKeeper via maven docker plugin https://dmp.fabric8.io/:
<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>
On this configuration, everything is working fine.
Right now I need to change the Kafka port(forwarded port for the host system) from 9092 to 9093.
In application.properties of my Spring Boot application I have added the following line:
spring.kafka.bootstrap-servers=127.0.0.1:9093
And also changed the configuration for Kafka image to:
<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>
and faced the following error:

What am I doing wrong and how to fix it?
Why NetworkClient is still trying to connect to 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.
UPDATED
I also tried the following env properties:
<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>
this way I have another LEADER_NOT_AVAILABLE error:
