一、整合步骤
1、开启Docker远程连接
既然要整合到IDEA，那么IDEA就需要连接Docker,所以我们需要开启Docker的远程连接。

使用以下命令编辑docker.service文件

1
vim /usr/lib/systemd/system/docker.service

添加如下内容

-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

测试命令

1
2
netstat -nlpt   #查看端口占用否
curl 192.168.33.11:2375/version    #如果能返回json数据，则证明成功

2、关闭防火墙（linux，自己测试用的）

  1. idea中配置docker

![image-20230611094407926](/Users/huage/Library/Application Support/typora-user-images/image-20230611094407926.png)

pom文件修改几处

  1. 镜像前缀

3
<properties>
    <docker.image.prefix>ngit</docker.image.prefix>
</properties>
  1. docker-build插件
