1.登录网站https://start.spring.io/，生成一个基本的SpringBoot应用。

2.将应用导入Eclipse IDE并创建Application类。目录结构如下：

Application代码如下：

@RequestMapping(value="/phone")

public String index(){

    return "Hello World!";

}

package com.example.demo.controller;

import org.springframework.web.bind.annotation.RequestMapping;


import org.springframework.web.bind.annotation.RestController;

@RestController


public class Application {
@<span class="hljs-keyword">RequestMapping</span>(<span class="hljs-keyword">value</span>="/<span class="hljs-keyword">phone</span>")

public String index(){

    <span class="hljs-selector-tag">return</span> "<span class="hljs-selector-tag">Hello</span> <span class="hljs-selector-tag">World</span>!";

}


}

3.在pom.xml文件中增加插件配置：

<!-- docker的maven插件，官网：https://github.com/spotify/docker-maven-plugin -->

            <plugin>

                <groupId>com.spotify</groupId>

                <artifactId>docker-maven-plugin</artifactId>

                <version>0.4.12</version>

                <configuration>

                    <!-- 注意imageName一定要是符合正则[a-z0-9-_.]的，否则构建不会成功 -->

                    <!-- 详见：https://github.com/spotify/docker-maven-plugin    Invalid repository name ... only [a-z0-9-_.] are allowed-->

                    <imageName>microservice-eureka-demo</imageName>

                    <baseImage>java</baseImage>

                    <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>

                    <resources>

                        <resource>

                            <targetPath>/</targetPath>

                            <directory>${project.build.directory}</directory>

                            <include>${project.build.finalName}.jar</include>

                        </resource>

                    </resources>

                </configuration>

            </plugin>

4.pom.xml文件中增加依赖：

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

        </dependency>

5.配置本地环境变量，设置docker文件构建主机（主机192.168.244.130已经安装完docker环境）

root@ubuntu-02:~# docker -v

Docker version 17.05.0-ce, build 89658be

本地环境变量配置如下：

6.进入代码目录，执行命令“mvn clean package docker:build”项目编译成功。

7.ssh连接192.168.244.130，执行命令“docker images”，查看可用的镜像：

root@ubuntu-02:~# docker images

REPOSITORY                                                           TAG                 IMAGE ID            CREATED             SIZE

microservice-eureka-demo                                             latest              1f800bf8cb24        23 minutes ago      658MB

8.执行命令“docker run -p 8080:8080 microservice-eureka-demo:latest”，使用镜像microservice-eureka-demo:latest启动docker容器。

root@ubuntu-02:~# docker run -p 8080:8080 microservice-eureka-demo:latest

9.执行命令“docker ps”，查看启动的docker容器。

root@ubuntu-02:~# docker ps


CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS                    NAMES


08099bd4b8e1        microservice-eureka-demo:latest   "java -jar /docker..."   27 seconds ago      Up 26 seconds       0.0.0.0:8080->8080/tcp   upbeat_borg

10.执行命令“docker exec -it 08099bd4b8e1 bin/bash”，进入docker容器。

root@ubuntu-02:~# docker exec -it 08099bd4b8e1 bin/bash

root@08099bd4b8e1:/#

11.执行命令“ps -ef”，可用查看到docker容器里面启动的进程，即是pom.xml配置文件中配置的插件docker-maven-plugin的entryPoint，java -jar /dockerdemo-0.0.1-SNAPSHOT.jar。

<entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>

root@08099bd4b8e1:/# ps -ef


UID         PID   PPID  C STIME TTY          TIME CMD


root          1      0  4 14:20 ?        00:00:17 java -jar /dockerdemo-0.0.1-SNAPSHOT.jar


root         34      0  0 14:24 ?        00:00:00 bin/bash


root         41     34  0 14:26 ?        00:00:00 ps -ef


root@08099bd4b8e1:/#

12.至此，使用docker插件构建docker镜像并运行docker容器完成，访问路径“http://192.168.244.130:8080/p...”，获得controller结果：
