-- index.html我在index.html上做了一个简单的网站：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>my journay to dockerising</title>
</head>
<body>
<p>this is an education project by me</p>
</body>
</html>并尝试在Dockerfile中使用apache2容器化：
FROM httpd:2.4.57
WORKDIR /Users/asklipios/Desktop/dockerable
COPY /Users/asklipios/Desktop/dockerable/index.html /
COPY . .
ENV port = 5000
EXPOSE 5000
CMD [ "httdp" ,"start"]当我奔跑时：docker run -t asklipios/exmple:1.0 /Users/asklipios/Desktop/dockerable它给了我这个：

你不能在dockerfile中使用绝对路径;dockerfile中的源路径相对于the root of the Docker build context。
根据to the docs for the image，您应该将HTML放在
/usr/local/apache2/htdocs/中，因此dockerfile应该是假设当前的工作目录是
index.html所在的目录，则命令应该是因此它使用当前工作目录作为Docker构建上下文，
dock/Dockerfile作为dockerfile。
