sudo apt update
如果这里之后有一个选项直接enter就行
sudo apt install nginx

开机自启动nginx，方便使用
sudo systemctl start nginx
sudo systemctl enable nginx

sudo apt install php-fpm php-mysql

自己按需求更改，这里我就改了个端口
sudo vim /etc/nginx/sites-available/default

sudo nginx -t
sudo systemctl restart nginx
sudo systemctl status nginx

Dockerfile写成dockerfile

mv dockerfile Dockerfile

格式不对Windows的文件格式和Linux不一样
file /mysite/mysite/start.sh
sudo apt-get install dos2unix
dos2unix /mysite/mysite/start.sh

ID问题，ID就是容器最前面那串数字
581cddd65fa6   my_site                               "/var/www/html/start…"   2 minutes ago   Up 2 minutes   5000/tcp, 0.0.0.0:8000->80/tcp, [::]:8000->80/tcp   inspiring_yonath

这里ID就是581cddd65fa6
