Recommended action: Configure separate listeners: an internal one advertised as kafka:29092 for containers and an external one advertised as localhost:9092 (mapped port) for the host; point each client at the listener for its network.
Option: Dual listeners [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. KAFKA_LISTENERS=INTERNAL://0.0.0.0:29092,EXTERNAL://0.0.0.0:9092
2. KAFKA_ADVERTISED_LISTENERS=INTERNAL://kafka:29092,EXTERNAL://localhost:9092
3. KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT and inter.broker.listener.name=INTERNAL
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
