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/112134818

2、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
控制台输出：
