我目前正在尝试弄清楚为什么
index.html我有以下内容：
index.html
Dockerfile
index.html<!DOCTYPE html>
<html>
<head>
<title>
First Web Page
</title>
</head>
<body>
Hello World! You are working!
</body>
</html>
DockerfileFROM ubuntu:22.04
RUN apt-get update
RUN apt-get install nginx -y
COPY index.html /var/www/html/
EXPOSE 80
CMD ["nginx","-g","daemon off;"]
根据无数教程，如果我创建图像并运行它，这应该可以工作：
docker build . -t my-web-site
docker run -p 8080:80 -d my-web-site
然而，我的容器不同意...

2023-04-25 21:40:57 nginx: [emerg] bind() to [::]:80 failed (98: Unknown error)

让这个看似简单的任务失败，我做错了什么？
