kafka setup from docker-compose

Question

Hi I'm currently setting up Kafka with Docker. If I mention like below in docker-compose, I am able to expose Kafka container to non-dockerized applications but docker applications are not able to connect to kafka.

  kafka:
    container_name: kafka
    build: docker/gravina-kafka
    image: gravina-kafka
    env_file: gravina.docker.env
    depends_on: [ zk ]
    ports:
      - "9092:9092"
    environment:
      ZOOKEEPER_ADDRESS=zk:2181
      KAFKA_ADDRESS=kafka:9092
      KAFKA_ADVERTISED_LISTENERS="PLAINTEXT://kafka:9092"
      KAFKA_LISTENERS="PLAINTEXT://:9092"
      KAFKA_ZOOKEEPER_CONNECT=zk:2181

If I add below environment variables, it is working, but when I mention KAFKA_ADVERTISED_LISTENERS="PLAINTEXT://kafka:9092" wont it consider for both external and internal to docker? I dont want to mention two different ports(one for internal and one for external).

KAFKA_LISTENERS="INTERNAL://:29092,EXTERNAL://:9092"
KAFKA_ADVERTISED_LISTENERS="INTERNAL://kafka:29092,EXTERNAL://localhost:9092"
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP="INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT"
KAFKA_INTER_BROKER_LISTENER_NAME="INTERNAL"

I checked some of the stackoverflow links, which did not help me, like: Kafka setup with docker-compose
