8.DockerMaven插件

一、修改宿主机的docker配置，让其可以远程访问

cat  /lib/systemd/system/docker.service
vim /lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:8085 -H unix:///var/run/docker.sock

systemctl daemon-reload
systemctl restart docker
docker start registry(3d211fb28d60或者id)

检查远程配置访问是否生效

在SpringBoot项目pom.xml增加配置

<build>
        <finalName>app</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- 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>0.4.13</version>
                <configuration>
                    <imageName>7.110.240.174:5000/${project.artifactId}:${project.version}</imageName>
                    <baseImage>jdk1.8</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>
                    <dockerHost>http://7.110.240.174:2375</dockerHost>
                </configuration>
            </plugin>
        </plugins>
    </build>

以上配置会自动生成Dockfile文件

FROM jdk1.8
ADD /app.jar //
ENTRYPOINT ["java", "-jar","/app.jar"]

 

 

在windows的命令提示符下，进入工程所在的目录

mvn install
mvn docker:build -DpushImage

执行后，镜像会上传到docker私有仓库，可以通过浏览器查看是否上传成功

二、测试创建Springt Boot项目结构

 

 

测试代码

WebApplication.java

package com.web.web;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class WebApplication {

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

}

 

 

HelloController.java

package com.web.web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;


/**
 * @author weihu
 * @Description TODO
 * @create 2020-06-10
 **/
@Controller
public class HelloController {

    @RequestMapping("/hello")
    @ResponseBody
    public String quick(){
        return "Hello weihubj shop!";
    }
}

 application.yml

server:
  port: 8086
