# 前言 #

docker介绍和安装参考菜鸟教程：[https://www.runoob.com/docker/docker-tutorial.html][https_www.runoob.com_docker_docker-tutorial.html]  
  
本次安装使用的环境为：

> CentOS7  
> Docker19.03.1  
> IntelliJ IDEA 2019.1.3 x64  
> Jdk1.8

# 步骤 #

## 配置Docker ##

1.  配置docker远程端口：

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

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzE4NDc2OQ_size_16_color_FFFFFF_t_70]  
如图所示，在最后追加： -H tcp://0.0.0.0:2375

1.  重启守护进程和docker

systemctl daemon-reload
     systemctl restart docker

1.  关闭防火墙，或者选择开放2375端口

sudo systemctl stop firewalld
    //永久关闭
    sudo systemctl disable firewalld

//开放端口
    firewall-cmd --zone=public --add-port=2375/tcp --permanent

## Idea配置 ##

1.  安装Docker插件并重启idea  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzE4NDc2OQ_size_16_color_FFFFFF_t_70 1]
2.  连接docker

## SpringBoot项目配置 ##

1.  首先创建项目，勾选web服务等基础，为了等下测试是否成功运行的页面。
2.  在main目录下创建文件夹docker，并创建dockerfile：  
    ![在这里插入图片描述][20190731150414781.png]

注意这个dockerfile没有后缀，直接右键docker文件夹new file，然后会有弹框选择

dockerfile中的内容暂时写：

FROM openjdk:8-jdk-alpine
    ADD *.jar app.jar
    ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

1.  配置pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

1.  添加配置：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzE4NDc2OQ_size_16_color_FFFFFF_t_70 6]  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzE4NDc2OQ_size_16_color_FFFFFF_t_70 7]  
    这里配置了端口的映射和日志文件的映射，比较简单
2.  maven打包  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzE4NDc2OQ_size_16_color_FFFFFF_t_70 8]必须留意一下是否打包成功  
    ![在这里插入图片描述][20190731151313604.png]
3.  启动dockerfile  
    ![在这里插入图片描述][20190731151343215.png]

等下下载依赖的镜像和文件，全部完成后留意一下输出的日志文件中是否成功  
![在这里插入图片描述][20190731151438300.png]

最后在浏览器中输入测试的页面就OK啦

真的是非常方便！
