一、开发前准备

1. Docker的安装可以参考https://docs.docker.com/install/

2. 配置docker远程连接端口

vi /usr/lib/systemd/system/docker.service

找到 ExecStart，在最后面添加 -H tcp://0.0.0.0:2375，如下图所示

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

(1) 编辑配置

(2) 填远程docker地址

(3) 连接成功，会列出远程docker容器和镜像

二、新建项目

1. 创建springboot项目

 项目结构图

(1) 配置pom文件
