Springboot2.4更新后提供了Spring Boot Maven 插件的 spring-boot:build-image 指令和 Gradle 插件的 bootBuildImage 任务现在可以直接发布 Docker 镜像到 Docker 注册中心了。
下面介绍Gradle的bootBuildImage方式
从网上找到一个图能说明这个过程
开发机器可以是windows系统，不安装 docker，使用一个中间机器运行docker，实现docker的打包和发送。 1、docker机器开启远程访问
参考：https://blog.csdn.net/u011943534/article/details/1121348182、将harbor服务器的地址配置到daemon.json中支持http访问vi /etc/docker/daemon.json
3、使用gradle创建springboot项目
过程略4、build.xml添加bootBuildImage任务bootBuildImage { imageName = ＂192.168.100.96:80/library/${project.name}:0.0.1＂ //发布到harbor的镜像名称 publish = true //是否发布 docker { host = ＂tcp://192.168.100.91:2375＂ //中间docker宿主机的地址 tlsVerify = false // certPath = ＂/home/users/.minikube/certs＂ publishRegistry { username = ＂admin＂ //harbor用户名 password = ＂Harbor12345＂ //harbor密码 url = ＂http://192.168.100.96＂ //harbor地址 email = ＂76775081@qq.com＂ //邮箱 } } }5、运行
运行gradle bootBuildImage 或在idea中点击运行bootBuildImage任务
第一次运行要下载依赖的镜像等，过程可能有点长
