本文主要介紹了springboot構(gòu)建docker鏡像并推送到阿里云，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

1.構(gòu)建springboot項(xiàng)目

工程目錄如下

UserController

package com.fandf.test.controller;  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RestController;  
/**  
* @author fandongfeng  
*/  
@RestController  
@RequestMapping("/api/v1/user")  
public class UserController {  
    @GetMapping("name")  
    public String getName() {  
        return "zhangsan";  
    }  
}

插件如果無(wú)法下載，可引入依賴

<dependency>
    <groupId>io.fabric8</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.40.1</version>
</dependency>

2.編寫Dockerfile

# 基礎(chǔ)鏡像使用Java
FROM java:8
# 作者
MAINTAINER fandongfeng
# VOLUME 指定了臨時(shí)文件目錄為/tmp。
# 其效果是在主機(jī) /var/lib/docker 目錄下創(chuàng)建了一個(gè)臨時(shí)文件，并鏈接到容器的/tmp
VOLUME /tmp
# 將jar包添加到容器中并更名為app.jar
# 此處可以把具體的jar包名稱寫出來(lái)，我這里直接用*號(hào)代替了
ADD target/*.jar app.jar
# 指定容器需要映射到主機(jī)的端口
EXPOSE 9091
ENTRYPOINT ["java","-jar","app.jar"]

項(xiàng)目maven plugins會(huì)有docker插件，點(diǎn)擊docekr build

鏡像已被上傳到本地

C:\Users\Administrator>docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
fandf/fdf-test 1.0.0 1a4b935b4d57 About an hour ago 684MB
java 8 d23bdf5b1b1b 6 years ago 643MB

3.推送鏡像到阿里云

登錄阿里云管控臺(tái) https://cr.console.aliyun.com/cn-chengdu/instances
選擇容器鏡像服務(wù)

新建鏡像倉(cāng)庫(kù)

按照提示上傳鏡像
