*  编写Dockerfile

FROM java:8
    
    COPY *.jar /app.jar
    
    CMD ["--server.port=8081"]
    
    EXPOSE 8081
    
    ENTRYPOINT ["java","-jar","/app.jar"]

*  编写docker-compose.yml

version: "3.7"
    services:
      netblog:
          build: .
          image: netblog
          depends_on:
            - mysql
          ports:
            - "8081:8081"
      mysql:
          restart: always
          image: mysql
          container_name: mysql
          ports:
            - "3306:3306"
          environment:
            MYSQL_DATABASE: javablog
            MYSQL_ROOT_PASSWORD: 123456
            MYSQL_ROOT_HOST: '%'
          volumes:
            - "/docker/mysql/db:/var/lib/mysql"
            - "/docker/mysql/conf/my.cnf:/etc/my.cnf"

注意：springboot链接mysql的url要写docker-compose中mysql的服务名

*  将springboot应用打包  
    注意：打包的时候要选择 skip test，否则链接mysql会报错

 *  将这两个文件和jar包上传到linux

*  进入这个mysql容器，将sql文件运行。
