java.rmi.server.ExportException: Port already in use: 7203

Hello,

I'm looking for good dockerized kafka environment for local development and found you repo suitable.

When I run "complex build" or make a docker-compose.yml everything started successfully but Kafka topic creation is failed with

kafka@ac447f2a0628:~$ kafka-topics.sh --create --topic test --replication-factor 1 --partitions 1 --zookeeper zookeeper:2181 Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 7203; nested exception is: java.net.BindException: Address already in use

Could you please help me with this?

Hi, it looks like you must be using docker exec to get that shell—please don't do that! Use docker run instead. Here's a longer rant about it: https://github.com/ches/docker-kafka/pull/11#issuecomment-292752506
