1.登陸網站https://start.spring.io/，生成一個基本的SpringBoot應用。html

2.將應用導入Eclipse IDE並建立Application類。目錄結構以下：java

Application代碼以下：git

package com.example.demo.controller;

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



@RestController
public class Application {
    
    @RequestMapping(value="/phone")
    public String index(){
        return "Hello World!";
    }
}

3.在pom.xml文件中增長插件配置：github

<!-- docker的maven插件，官網：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必定要是符合正則[a-z0-9-_.]的，不然構建不會成功 -->
                    <!-- 詳見：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文件中增長依賴：web

<dependency>  
            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-web</artifactId>  
        </dependency>

5.配置本地環境變量，設置docker文件構建主機（主機192.168.244.130已經安裝完docker環境）spring

root@ubuntu-02:~# docker -v
Docker version 17.05.0-ce, build 89658be

本地環境變量配置以下：

6.進入代碼目錄，執行命令「mvn clean package docker:build」項目編譯成功。apache

7.ssh鏈接192.168.244.130，執行命令「docker images」，查看可用的鏡像：ubuntu

root@ubuntu-02:~# docker images
REPOSITORY                                                           TAG                 IMAGE ID            CREATED             SIZE
microservice-eureka-demo                                             latest              1f800bf8cb24        23 minutes ago      658MB

8.執行命令「docker run -p 8080:8080 microservice-eureka-demo:latest」，使用鏡像microservice-eureka-demo:latest啓動docker容器。bash

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

9.執行命令「docker ps」，查看啓動的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.執行命令「docker exec -it 08099bd4b8e1 bin/bash」，進入docker容器。

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

11.執行命令「ps -ef」，可用查看到docker容器裏面啓動的進程，便是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插件構建docker鏡像並運行docker容器完成，訪問路徑「http://192.168.244.130:8080/p...」，得到controller結果：
