1.登錄網(wǎng)站https://start.spring.io/，生成一個(gè)基本的SpringBoot應(yīng)用。

2.將應(yīng)用導(dǎo)入Eclipse IDE并創(chuàng)建Application類(lèi)。目錄結(jié)構(gòu)如下：

Application代碼如下：

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文件中增加插件配置：

            
                com.spotify
                docker-maven-plugin
                0.4.12
                
                    
                    
                    microservice-eureka-demo
                    java
                    ["java", "-jar", "/${project.build.finalName}.jar"]
                    
                        
                            /
                            ${project.build.directory}
                            ${project.build.finalName}.jar
                        
                    
                
            

4.pom.xml文件中增加依賴(lài)：

          
            org.springframework.boot  
            spring-boot-starter-web  
        

5.配置本地環(huán)境變量，設(shè)置docker文件構(gòu)建主機(jī)（主機(jī)192.168.244.130已經(jīng)安裝完docker環(huán)境）

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

本地環(huán)境變量配置如下：

6.進(jìn)入代碼目錄，執(zhí)行命令“mvn clean package docker:build”項(xiàng)目編譯成功。

7.ssh連接192.168.244.130，執(zhí)行命令“docker images”，查看可用的鏡像：

root@ubuntu-02:~# docker images
REPOSITORY                                                           TAG                 IMAGE ID            CREATED             SIZE

8.執(zhí)行命令“docker run -p 8080:8080 microservice-eureka-demo:latest”，使用鏡像microservice-eureka-demo:latest啟動(dòng)docker容器。

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

9.執(zhí)行命令“docker ps”，查看啟動(dòng)的docker容器。

root@ubuntu-02:~# docker ps
CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS                    NAMES

10.執(zhí)行命令“docker exec -it 08099bd4b8e1 bin/bash”，進(jìn)入docker容器。

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

11.執(zhí)行命令“ps -ef”，可用查看到docker容器里面啟動(dòng)的進(jìn)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。

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

root@08099bd4b8e1:/# ps -ef

12.至此，使用docker插件構(gòu)建docker鏡像并運(yùn)行docker容器完成，訪問(wèn)路徑“http://192.168.244.130:8080/p...”，獲得controller結(jié)果：
