Kafka does not start on Docker Compose?

I use Kafka in my Docker Compose file. My docker-compose.yaml looks like this:

version: '3.3'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: localhost # DEPRECATED property
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Unfortunately, when I start and restart Kafka’s instance in Docker Compose I was constantly getting random errors. After some googling, I found that KAFKA_ADVERTISED_HOST_NAME is deprecated – please see https://github.com/wurstmeister/kafka-docker/wiki/Connectivity

So, changing my docker-compose.yaml to

version: '3.3'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_LISTENERS: PLAINTEXT://:9092 # This new property
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092 # And this new property
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Helped – no more errors when starting Kafka on Docker.
