First time working with Kafka and Docker-compose. I'm trying to publish a message to Kafka but I get an error (look below). What is the issue?
2020-07-21 16:37:40,274 WARN [kafka-producer-network-thread | producer-1] org.apache.kafka.clients.NetworkClient$DefaultMetadataUpdater: [Producer clientId=producer-1] 1 partitions have leader brokers without a matching listener, including [demo-topic-0]
Here is my docker-compose.yml:
