（一）拉取nginx镜像

$root@Client my-nginx-web$ # docker login uhub.service.ucloud.cn ##输入注册的账号密码

$root@Client my-nginx-web$ #docker pull uhub.service.ucloud.cn/ucloud/nginx:1.28.2

（二）编写Dockerfile

$root@Client my-nginx-web$ #vim Dockerfile

1. 基于官方 nginx 镜像

FROM nginx:latest

2. 删除默认网页

RUN rm -rf /usr/share/nginx/html/*

3. 拷贝自己的网页文件

COPY html/ /usr/share/nginx/html/

4. 暴露 80 端口

EXPOSE 80

（三）构建镜像

$root@Client my-nginx-web$ # docker build -t my-nginx:v1 .
