springboot（三十）gradle将服务打包为镜像推送至harbor镜像私服

　　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
