HTML 应用构建
HTML 语言 demo docker 镜像构建
目标：基于 nginx 的 Docker 基础镜像，开发一个静态的 HTML 示例应用 (hello world)
新建 html-demo 目录
mkdir html-demo
cd html-demo
编写 HTML 示例
将如下内容保存为 index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello,world</title>
</head>
<body>
<h1>hello, world</h1>
<p>这是一个静态 html 页面</p>
</body>
</html>
编写 Dockerfile
将如下内容保存为 Dockerfile
FROM nginx:1.15-alpine
COPY . /usr/share/nginx/html
EXPOSE 80
CMD nginx -g "daemon off;"
构建镜像编译
整个 html-demo 材料包括如下 Dockerfile, index.html 两个文件
[root@localhost html-demo]# tree .
.
├── dockerfile
└── index.html
在 html-demo 项目目录执行如下构建命令
docker build -t registry.cosmoplat.com/test/helloworld_html:v0.0.1 .
执行成功的完整过程如下

测试镜像
上传镜像前先在本地做下测试，运行如下命令
docker run -d --name test_html -p 20080:80 registry.cosmoplat.com/test/helloworld_html:v0.0.1
curl localhost:20080
容器运行正常会看到 Hello world 字样
