# 1、准备环境 #

## 1.1、安装Docker ##

[安装Docker][Docker]

## 1.2 .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

## 1.3、重启docker ##

systemctl daemon-reload
    systemctl start docker

## 1.4 、开放端口 ##

针对防火墙不能关键的情况下，可以选择开放端口

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

# 2、配置Idea链接docker #

## 2.1 选择Docker如下图所示 ##

## 2.2 编辑配置 ##

添加server配置

成功连接远程docker！

# 3. 新建项目 #

## 3.1 整体目录结构 ##

## 3.2 配置pom文件 ##

## 3.3 创建Dockerfile文件 ##

在src/main/docker目录下创建docker目录，并创建Dockerfile文件

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

## 3.4.在resource目录下创建application.properties文件 ##

logging.path=/home/developer/app/logs/
    server.port=8990

## 3.5.创建DockerApplication文件 ##

package org.example;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @author : 寻找手艺人
     * @version V1.0
     * @Project: springboot-docker-demo
     * @Package org.example
     * @Description: TODO
     * @date Date : 20200623 11:21
     */
    @SpringBootApplication
    public class DockerApplication {
        
        public static void main(String[] args) {
        
            SpringApplication.run(DockerApplication.class, args);
        }
    }

## 3.6.创建DockerController文件 ##

package org.example.doc.controller;
    
    import org.apache.commons.logging.Log;
    import org.apache.commons.logging.LogFactory;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @author : 寻找手艺人
     * @version V1.0
     * @Project: springboot-docker-demo
     * @Package org.example.doc.controller
     * @Description: TODO
     * @date Date : 20200623 11:22
     */
    @RestController
    public class DockerController {
        
        static Log log = LogFactory.getLog(DockerController.class);
        @RequestMapping("/")
        public String index() {
        
            log.info("Hello Docker!");
            return "Hello Docker!";
        }
    }

## 3.7 配置dockerfile ##

参数说明：

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。

# 4.打包运行 #

## 4.1 选择maven打包 ##

## 4.2.运行 ##

先pull基础镜像，然后再打包镜像，并将镜像部署到远程docker运行
