dockerfile-maven-plugin極簡(jiǎn)教程(推薦)

更新時(shí)間：2020年10月13日 09:32:04 作者：陳明亮

這篇文章主要介紹了dockerfile-maven-plugin極簡(jiǎn)教程，本文給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

一、簡(jiǎn)介

maven是一個(gè)項(xiàng)目依賴管理和構(gòu)建的工具，dockerfile-maven-plugin是一個(gè)maven的插件，主要作用是在項(xiàng)目構(gòu)建的時(shí)候生成基于項(xiàng)目的docker鏡像文件。

簡(jiǎn)而言之，此插件將maven和docker進(jìn)行集成。

正常情況下，我們?cè)陂_發(fā)了一個(gè)應(yīng)用程序后，會(huì)使用maven進(jìn)行打包，生成對(duì)應(yīng)的jar文件。而后，會(huì)使用docker將jar文件build成一個(gè)鏡像（docker image）。之后，就可以在docker daemon中創(chuàng)建基于鏡像的容器，并可提供服務(wù)了。

dockerfile-maven-plugin的目標(biāo)就是將maven的打包過程和docker的build過程結(jié)合在一起，當(dāng)成功打包，既生成了對(duì)應(yīng)的jar，也已生成了對(duì)應(yīng)的docker鏡像。當(dāng)然，這只是最基礎(chǔ)的功能，更詳細(xì)的功能參見：https://github.com/spotify/dockerfile-maven

二、概述

我們知道m(xù)aven是apache公司開發(fā)的一個(gè)產(chǎn)品，但是dockerfile-maven-plugin并不是apache官方開發(fā)的插件，是由一個(gè)叫做Spotify的組織開發(fā)的。

github主頁(yè)：https://spotify.github.io/

github開源地址：https://github.com/spotify/dockerfile-maven

本文僅討論如何基于一個(gè)Spring Boot的項(xiàng)目生成對(duì)應(yīng)的docker鏡像。

基本的原理如下：

首先，dockerfile-maven-plugin插件已經(jīng)存儲(chǔ)在maven的倉(cāng)庫(kù)中
然后，當(dāng)在本地開發(fā)的時(shí)候，需要在項(xiàng)目的pom文件中引入此插件，在pom-build-plugins下面增加plugin配置節(jié)點(diǎn)
再然后，在executions節(jié)點(diǎn)中配置此插件如何工作；并且在configuration節(jié)點(diǎn)中加入需要的配置信息
最后，當(dāng)我們執(zhí)行mvn package的時(shí)候就可以得到docker image 了

環(huán)境：

Ideal版本：2020.01
java版本：8
maven版本：3.6.1
docker版本：19.03.12

ideal和docker deamon運(yùn)行在同一臺(tái)機(jī)器上面

三、將spring-boot-app打包成docker鏡像

創(chuàng)建示例應(yīng)用

使用ideal自帶的Spring Initializr生成一個(gè)Spring Web 的示例項(xiàng)目

app對(duì)外提供一個(gè)hello的接口，訪問該接口可以得到Hello，World的響應(yīng)結(jié)果。應(yīng)用主啟動(dòng)類代碼如下：

package com.naylor.dockerfilemavenplugin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/")
@SpringBootApplication
public class DockerfileMavenPluginApplication {

  public static void main(String[] args) {
    SpringApplication.run(DockerfileMavenPluginApplication.class, args);
  }

  @GetMapping("/hello")
  public String hello(){
    return "Hello,World";
  }

}

編譯并運(yùn)行項(xiàng)目，在瀏覽器中訪問「http://127.0.0.1:8080/hello」可以得到預(yù)期的響應(yīng)結(jié)果

修改pom文件

在pom中增加對(duì)dockerfile-maven-plugin插件的引用，核心代碼如下:

 <!--  dockerfile-maven-plugin   -->
      <plugin>
        <groupId>com.spotify</groupId>
        <artifactId>dockerfile-maven-plugin</artifactId>
        <version>1.3.6</version>
        <executions>
          <execution>
            <id>default</id>
            <goals>
              <goal>build</goal>
              
            </goals>
          </execution>
        </executions>
        <configuration>
          <repository>com.naylor/${project.artifactId}</repository>
          <tag>${project.version}</tag>
          <buildArgs>
            <JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
          </buildArgs>
        </configuration>
      </plugin>

其中：

g,a,v 為對(duì)插件的引用
executions中的build標(biāo)識(shí)，在maven的packege環(huán)節(jié)執(zhí)行此插件
configuration中的repository是生成的鏡像的repository信息
tag為鏡像的tag信息
buildArgs是在docker構(gòu)建鏡像過程中的參數(shù)，此處定義的JAR_FILE參數(shù)在執(zhí)行docker build 的時(shí)候會(huì)消費(fèi)

完整的pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          </buildArgs>
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>

增加Dockerfile文件

在項(xiàng)目根目錄（和pom文件在同一級(jí)）新建一個(gè)Dokerfile文件，文件內(nèi)容如下:

FROM java:8
EXPOSE 8080
ARG JAR_FILE
ADD target/${JAR_FILE} /app.jar
ENTRYPOINT ["java", "-jar","/app.jar"]

使用Maven打包應(yīng)用

首先清理一下maven工程，在ideal的Maven面版中點(diǎn)擊Lifecycle-clean或者使用命令行執(zhí)行mvn clean。

然后，使用maven構(gòu)建app，在ideal的Maven面版中點(diǎn)擊Liftcycle-package或者使用命令行執(zhí)行 mvn package

再然后在命令行工具中執(zhí)行docker image ls ，如果不出意外，可以看到一個(gè)repository為com.naylor/dockerfile-maven-plugin的docker鏡像。

運(yùn)行應(yīng)用鏡像

在命令行工具中執(zhí)行如下命令運(yùn)行容器：

docker run -d -p 8081:8080 ImageId

ImageId為上一步生成的鏡像的id，每次生成的鏡像id都不一樣
此命令作用為基于ImageId構(gòu)建一個(gè)容器，將宿主機(jī)的8081端口映射到容器的8080端口

在宿主機(jī)瀏覽器中訪問「http://127.0.0.1:8081/hello」可以得到Hello,World的響應(yīng)。

四、分析mvn package 命令的控制臺(tái)輸出

通過mvn package的控制臺(tái)輸出，我們可以清晰的觀察到整個(gè)流程的執(zhí)行步驟，完整的輸出如下:

dockerfile中一共定義了5步來執(zhí)行構(gòu)建，第一步是拉取java8的鏡像，如果本地沒有會(huì)從遠(yuǎn)程倉(cāng)庫(kù)中搜索并下載下來
