spring boot项目打包成docker推送到远程仓库_docker推送springboot项目到远程仓库-优快云博客

博客介绍了Spring Boot项目基于Docker的部署流程。首先需安装Docker，接着在阿里云开通镜像服务，包括创建命名空间和镜像仓库。然后进行项目配置，如pom、maven setting配置，编写Dockerfile文件，用maven打包成镜像。最后给出了jenkins部署脚本。

maven setting 配置，servers添加阿里云远程仓库账号

    <server>
      <id>docker-aliyun</id>
      <username>name</username>
      <password>passwork</password>
	  <configuration>
        <email>123456@qq.com</email>
      </configuration>
   </server>

Dockerfile文件

FROM hub.c.163.com/library/java:8
EXPOSE 8080
VOLUME /tmp
ADD target/app-service-2.0.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

使用 maven 打包即可将jar包打成镜像

mvn clean package

4.jenkins 部署脚本

#!/bin/sh

docker stop app-service || true
docker rm app-service || true
docker rmi app-service || true

docker pull registry.cn-hangzhou.aliyuncs.com/aliyun-syg/app-service:2.0
docker run -d -p 8080:8080 --name app-service -e active=xxxxx dev.cn-hangzhou.aliyuncs.com/aliyun-syg/app-service:2.0
