如何在 docker-compose.yml 中创建 kafka 集群和主题

Question

我是 docker 新手。我想将 kafka 容器化并添加一个集群，比如 MyCluster，然后在 kafka 服务器启动后立即向集群添加 4 个主题，例如 topic_a、topic_b、topic_c 和 topic_d。有人可以向我解释如何做到这一点吗？我尝试了以下 docker-compose.yml 并且能够启动容器化的 kafka 服务器和 kafka 管理器，但我无法以编程方式创建集群/主题。请帮忙！

version: "2"

services:
  kafkaserver:
    image: "spotify/kafka:latest"
    container_name: kafka
    hostname: kafkaserver
    networks:
      - kafkanet
    ports:
      - 2181:2181
      - 9092:9092
    environment:
      ADVERTISED_HOST: kafkaserver
      ADVERTISED_PORT: 9092
    command:
      /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper kafkaserver:2181 --replication-factor 1 --partitions 1 --topic topic_a
      /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper kafkaserver:2181 --replication-factor 1 --partitions 1 --topic topic_b
      /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper kafkaserver:2181 --replication-factor 1 --partitions 1 --topic topic_c
      /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper kafkaserver:2181 --replication-factor 1 --partitions 1 --topic topic_d

  kafka_manager:
    image: "mzagar/kafka-manager-docker:1.3.3.4"
    container_name: kafkamanager
    networks:
      - kafkanet
    ports:
      - 9000:9000
    links:
      - kafkaserver
    environment:
      ZK_HOSTS: "kafkaserver:2181"

networks:
  kafkanet:
    driver: bridge

我在我的 docker-compose 文件中使用了这个配置。整个文件可以在这里找到https://github.com/felipegutierrez/explore-flink/blob/master/operations-playground/docker-compose.yaml

  zookeeper:
    image: wurstmeister/zookeeper:3.4.6
    restart: always
  kafka:
    image: wurstmeister/kafka:2.12-2.2.1
    environment:
      KAFKA_ADVERTISED_LISTENERS: INSIDE://:9092,OUTSIDE://:9094
      KAFKA_LISTENERS: INSIDE://:9092,OUTSIDE://:9094
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
      KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
      KAFKA_CREATE_TOPICS: "input:2:1, output:2:1"
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    ports:
      - 9094:9094
    restart: always
