（1）准备依赖的镜像，包括mariadb、jdk1.8、nginx，配置docker-compose.yml文件

services:
  mariadb:
    image: mariadb
    ports:
      - "3314:3306"
    environment:
      - MARIADB_ROOT_PASSWORD=123456
    volumes:
      - ./mysql:/var/lib/mysql
    networks:
      - qingpu
  dispatch:
    image: jdk1.8:1.0
    ports:
      - "1234:8080"
    volumes:
      - ./dispatch/application.properties:/home/application.properties
      - ./dispatch/application-test.properties:/home/application-test.properties
      - ./dispatch/dispatch-0.0.1.jar:/home/dispatch-0.0.1.jar
      - ./dispatch/logback-plus.xml:/home/logback-plus.xml
      - ./dispatch/logs:/home/logs
    working_dir: /home
    depends_on:
      - mariadb
    command: java -jar dispatch-0.0.1.jar
    networks:
      - qingpu
  nginx:
    image: nginx
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
      - ./nginx/html:/home/html
    depends_on:
      - dispatch
    ports:
      - "82:80"
    networks:
      - qingpu
networks:
  qingpu: {}

其中mariadb是关系型数据库，dispatch是java可执行jar包，nginx是web服务器，目录结构如下

（2）构建、运行容器，查询容器，查看进程

PS E:\docker\qingpu> docker-compose up -d
