5. DockerCompose

Docker Compose通过一个单独的docker-compose.yml 模板文件（YAML 格式）来定义一组相关联的应用容器，帮助我们实现多个相互关联的Docker容器的快速部署。

docker compose的命令格式如下：

docker compose [OPTIONS] [COMMAND]

version: "3.8"
services:
  mysql:
    image: mysql
    container_name: mysql
    ports:
      - "3306:3306"
    environment:
      TZ: Asia/Shanghai
      MYSQL_ROOT_PASSWORD: 123
    volumes:
      - "./mysql/conf:/etc/mysql/conf.d"
      - "./mysql/data:/var/lib/mysql"
      - "./mysql/init:/docker-entrypoint-initdb.d"
    networks:
      - new
  hmall:
    build:
       context: .
       dockerfile: Dockerfile
    container_name: hmall
    ports:
      - "8080:8080"
    networks:
      - new
    depends_on:
      - mysql
  nginx:
    image: nginx
    container_name: nginx
    ports:
      - "18080:18080"
      - "18081:18081"
    volumes:
      - "./nginx/nginx.conf:/etc/nginx/nginx.conf"
      - "./nginx/html:/etc/nginx/html"
    depends_on:
      - hmall
    networks:
      - new
networks:
  new:
    name: hmall
