使用IDEA的Docker插件一键部署SpringBoot项目，是打包运维变得非常便利，linux上安装docker->IDEA安装插件连接到Docker服务->项目打包->docker打包->linux运行docker服务。

Docker插件配置：
先打包项目
target下面出现
双击docker-build
镜像完成
Docker运行，注意-p为端口映射：
[root@localhost ~]# docker run --name web -d -p 8080:8080 ww/dtest:latest
65bb7f9434c0b09fbada4885ab15268b411cbcfcdd2c40077bb52938a7756d9d
返回的这个字符串就是这个进程ID，查看日志需要
Docker日志查看：
[root@localhost ~]# docker logs 65bb7f9434
