使用docker Maven插件本地构建docker镜像并发布到远程服务器
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：
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!";
}
}
" title="" data-original-title="复制">
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：
com.spotify
docker-maven-plugin
0.4.12
microservice-eureka-demo
java
["java", "-jar", "/${project.build.finalName}.jar"]
/
${project.build.directory}
${project.build.finalName}.jar
" title="" data-original-title="复制">
<!-- docker的maven插件，官网：https://github.com/spotify/docker-maven-plugin -->
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.12</version>
<configuration>
<!-- 注意imageName一定要是符合正则[a-z0-9-_.]的，否则构建不会成功 -->
<!-- 详见：https://github.com/spotify/docker-maven-plugin Invalid repository name ... only [a-z0-9-_.] are allowed-->
<imageName>microservice-eureka-demo</imageName>
<baseImage>java</baseImage>
<entryPoint>["java", "-jar", "/${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：
org.springframework.boot
spring-boot-starter-web
" title="" data-original-title="复制">
<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。
