Kafka + Zookeeper: Connection to node -1 could not be established. Broker may not be available

Question

I am running in my locahost both Zookeeper and Kafka (1 instance each).

I create succesfully a topic from kafka:

./bin/kafka-topics.sh --zookeeper lo         


        

Answer 1

If this happens suddenly after it was working, you should try to restart Kafka first.

In my case, restarting solved the problem:

$docker-compose down && docker-compose up -d
