1、Docker安装
2、配置docker远程连接端口
vi /usr/lib/systemd/system/docker.service
3、重启docker
systemctl daemon-reload
systemctl start docker
4、开放端口
firewall-cmd --zone=public --add-port=2375/tcp --permanent
5、Idea安装插件,重启
6、连接远程docker
创建Spring Boot项目

Image tag : 指定镜像名称和tag,镜像名称为 docker-demo,tag为1.1 Bind ports : 绑定宿主机端口到容器内部端口。格式为[宿主机端口]:[容器内部端口] Bind mounts : 将宿主机目录挂到到容器内部目录中。
格式为[宿主机目录]:[容器内部目录]。这个springboot项目会将日志打印在容器 /home/developer/app/logs/ 目录下,将宿主机目录挂载到容器内部目录后,那么日志就会持久化容器外部的宿主机目录中。
