docker-compose安装kafka和zookeepr

1. docker-compose.yml文件内容如下：

version: '2'
services:
  zookeeper:
    image: zookeeper:3.5.8
    container_name: zookeeper
    restart: always
    hostname: zookeeper
    ports:
      - "2181:2181"

  kafka:
    image: wurstmeister/kafka:2.12-2.5.0
    container_name: kafka
    hostname: kafka
    restart: always
    ports:
      - "9092:9092"
      - "7203:7203"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: 10.250.115.210
      KAFKA_ZOOKEEPER_CONNECT: "10.250.115.210:2181"

2. 使用docker-compose安装

docker-compose up -d

3. 查看日志

docker logs -f kafka

4. 注意事项
   其他容器想连接kafka时，最好通过"kafka:9092"，即"容器名称:端口号"。
