（1）准备依赖的镜像，包括mariadb、jdk1.8、nginx，配置docker-compose.yml文件
services:mariadb:image: mariadbports:- "3314:3306"environment:- MARIADB_ROOT_PASSWORD=123456volumes:- ./mysql:/var/lib/mysqlnetworks:- qingpudispatch:image: jdk1.8:1.0ports:- "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/logsworking_dir: /homedepends_on:- mariadbcommand: java -jar dispatch-0.0.1.jarnetworks:- qingpunginx:image: nginxvolumes:- ./nginx/nginx.conf:/etc/nginx/nginx.conf- ./nginx/default.conf:/etc/nginx/conf.d/default.conf- ./nginx/html:/home/htmldepends_on:- dispatchports:- "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
