2.3 创建 docker.html 文件
将以下代码复制到 docker.html 文件中，并保存：
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>镜像使用说明</title>
<style>
body {
font-family: 'Roboto', sans-serif;
margin: 0;
padding: 0;
background-color: #f4f4f4;
}
.header {
background: linear-gradient(135deg, #667eea, #764ba2);
color: #fff;
padding: 20px 0;
text-align: center;
box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
}
.container {
max-width: 800px;
margin: 40px auto;
padding: 20px;
background-color: #fff;
box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
border-radius: 10px;
}
.content {
margin-bottom: 20px;
}
.footer {
text-align: center;
padding: 20px 0;
background-color: #333;
color: #fff;
}
pre {
background-color: #272822;
color: #f8f8f2;
padding: 15px;
border-radius: 5px;
overflow-x: auto;
}
code {
font-family: 'Source Code Pro', monospace;
}
a {
color: #4CAF50;
text-decoration: none;
}
a:hover {
text-decoration: underline;
}
@media (max-width: 600px) {
.container {
margin: 20px;
padding: 15px;
}
.header {
padding: 15px 0;
}
}
</style>
<link href="https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&family=Source+Code+Pro:wght@400;700&display=swap" rel="stylesheet">
</head>
<body>
<div class="header">
<h1>镜像使用说明</h1>
</div>
<div class="container">
<div class="content">
<p>为了加速镜像拉取，你可以使用以下命令设置 registry mirror:</p>
<pre><code>sudo tee /etc/docker/daemon.json <<EOF
{
"registry-mirrors": ["https://xxx.com"] #这里改成xxx.com 网页上就显示xxx.com
}
EOF</code></pre>
<p>为了避免 Worker 用量耗尽，你可以手动 pull 镜像然后 re-tag 之后 push 至本地镜像仓库:</p>
<pre><code>docker pull {{host}}/library/alpine:latest # 拉取 library 镜像
docker pull {{host}}/coredns/coredns:latest # 拉取 coredns 镜像</code></pre>
</div>
</div>
</body>
</html>
