Dockerfile 构建自定义 Nginx Web 服务镜像
（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 .

（四）查看构建的镜像
[root@Client my-nginx-web]# docker images
IMAGE ID DISK USAGE CONTENT SIZE EXTRA
centos:latest a27fd8080b51 335MB 83.5MB U
centos:v1 2061d526cd3a 335MB 83.5MB U
my-nginx:v1 f7b4d6a44636 234MB 63MB
nginx:latest 7150b3a39203 237MB 65.8MB
（五）运行my-nginx:v1
[root@Client my-nginx-web]# docker run -d -p 8080:80 --name myweb my-nginx:v1
（六）访问网页
（七）进入容器
[root@Client my-nginx-web]# docker exec -it myweb /bin/bash
root@3877bac6520a:/# cat /usr/share/nginx/html/index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>My Nginx Site</title>
</head>
<body>
<h1>Hello Docker + Nginx!</h1>
<p>这是我的自定义 Nginx 镜像。</p>
