我尝试在 Windows 10 机器中使用 Jenkins“Docker Build and Publish”插件构建 docker 映像。为此，我从 docker 中提取了 jenkins 映像。我的要求是，在 jenkins 映像之上，我需要创建一项作业[来自 GIT 的 SCM -> 构建 Maven jar -> 使用 DockerFile，尝试构建 docker 映像并将其推送到 dockerhub]。
First inside Jenkins-> Manage Jenkins ->Global tool configuration ->Add docker
后来我尝试创建詹金斯自由式工作。在其中我添加了我的 GITlab 项目 url 和凭据。
In Build section, first i configured Maven
“Docker 构建和发布”部分中的第二个，
存储库名称作为我的 dockerhub 存储库名称
DOCKER HOST URI - 来自命令“docker-machine env 'docker-machine-name'”的 Docker 主机地址
And then i clicked Advanced tab in BUILD section, added docker( the one which i add in Jenkins-> Manage Jenkins ->Global tool configuration ->Add docker)
每当我运行 jenkins 作业时，它都会从 GITLab 中提取代码，然后 Maven 成功创建 jar。在我尝试使用 Dockerfile 构建 docker 镜像之后。
我的 Docker 文件：

在调试时，我在浏览器中尝试了 docker 主机 uri，出现错误“客户端向 HTTPS 服务器发送了 HTTP 请求。”
我错过了什么。请帮我解决这个问题
NOTE: I tried to build docker image & push that to dockerhub using command prompt. Successfully i can create and push to dockerhub.
