springboot构建docker镜像并推送到阿里云
1.构建springboot项目
工程目录如下
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;
@RestController
@RequestMapping("/api/v1/user")
public class UserController {
@GetMapping("name")
public String getName() {
return "zhangsan";
}
}application.yml

</project>插件如果无法下载，可引入依赖
<dependency>
<groupId>io.fabric8</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.40.1</version>
</dependency>2.编写Dockerfile
# 基础镜像使用Java
FROM java:8
# 作者
MAINTAINER fandongfeng
# VOLUME 指定了临时文件目录为/tmp。
# 其效果是在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为app.jar
# 此处可以把具体的jar包名称写出来，我这里直接用*号代替了
ADD target/*.jar app.jar
# 指定容器需要映射到主机的端口
EXPOSE 9091
ENTRYPOINT ["java","-jar","app.jar"]项目maven plugins会有docker插件，点击docekr build

3.推送镜像到阿里云
登录阿里云管控台 https://cr.console.aliyun.com/cn-chengdu/instances
选择容器镜像服务
新建镜像仓库
按照提示上传镜像
