What is the extra random port in kafka and how to set it to bind to localhost? #789

This happens on host and docker images, besides the famous 9092:9093 port, there is another dynamic port that kafka listens to.

I am using the /usr/local/kafka/bin/kafka-server-start.sh to run kafka.

ps -ef |grep kafka |grep -v grep |awk '{print $2}' 15580

netstat -tnpl |grep 15580 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) *tcp6 0 0 :::37023 ::: LISTEN 15580/java*
tcp6 0 0 192.168.64.18:9092 ::: LISTEN 15580/java
tcp6 0 0 192.168.64.18:9093 :::* LISTEN 15580/java

What is the port "37023" above? how to disable it? Can it be bind to "localhost" ?
