测试--curl http://192.168.172.128:2375/version
基础环境
Idea: 2019.1.3
Docker: 20.10.2
Centos: 7.8
Docker开启远程API
修改docker.service文件
vim /usr/lib/systemd/system/docker.service
需要修改的部分：
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
修改后的部分：
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
配置生效
systemctl daemon-reload
重新启动Docker服务
systemctl stop docker
systemctl start docker
开启2375端口
firewall-cmd --zone=public --add-port=2375/tcp --permanent firewall-cmd --reload
测试--curl http://192.168.172.128:2375/version

Idea 集成Docker
在IDEA中打开File -> Settings菜单，在插件市场中搜索Docker插件，并安装
Docker插件
配置连接Docker服务端
连接成功，如下所示
问题：
idea 底层显示docker窗口
