Connecting Kafka producer to Kafka broker in Docker through Java

General

Ok, now the docker-compose.yml is:

version: '2'

services:
  zookeeper:
    image: 'bitnami/zookeeper:3'
    ports:
      - '2181:2181'
    volumes:
      - 'zookeeper_data:/bitnami'
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes
  kafka:
    image: 'bitnami/kafka:2'
    ports:
      - '9092:9092'
    volumes:
      - 'kafka_data:/bitnami'
    environment:
      - KAFKA_BROKER_ID=1
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
      - KAFKA_CFG_LISTENERS=PLAINTEXT://:9092,PLAINTEXT_HOST://:9092
      - KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092,PLAINTEXT_HOST://localhost:9092
      - KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper:2181
      - KAFKA_SERVER_PORT=9092
      - ALLOW_PLAINTEXT_LISTENER=yes
    depends_on:
      - zookeeper

volumes:
  zookeeper_data:
    driver: local
  kafka_data:
    driver: local

And obviously I changed the port used in the app to 9092.

But still, I have the same problem as before.
