mvn package docker:build

1.登录网站[https://start.spring.io/][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：

![clipboard.png][]

Application代码如下：

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：

<plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>0.4.12</version>
                    <configuration>
                        
                        
                        <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：  
![clipboard.png][clipboard.png 1]

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...][http_192.168.244.130_8080_p...]”，获得controller结果：
