先用docker建let's encrypt
sudo docker run --rm -p 80:80 -p 443:443 -v /etc/letsencrypt:/etc/letsencrypt quay.io/letsencrypt/letsencrypt auth --standalone -m email@domain --agree-tos -d example.com
此时已经生成let's encrypt 的证书
然后调用Nginx
sudo docker run --name nginx -v /etc/letsencrypt:/etc/letsencrypt -d -p 80:80 -p 443:443 -d nginx
搞定后进入contianer里面
sudo docker exec -it container_number /bin/bash
修改Ngnix的配置文件（在 /etc/nginx/conf.d 里面）的default.conf
在listen 80; 下面加这几行
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
搞定后退出容器重启容器
sudo docker restart container_number
然后还要将自己的网站放在 /usr/share/nginx/html/ 下面
sudo docker cp example.html container_number:/usr/share/nginx/html/example.html
然后就搞定
