## Host reverse proxy
The reverse proxy on a host forwards to the designated LXC container with
something like the following in
`/etc/nginx/sites-available/example.com`, where A.B.C.D is the
IP allocated to the LXC container running the web service:
The certificate is obtained once and automatically renewed with:
```
sudo apt-get install certbot python3-certbot-nginx
sudo certbot -n --agree-tos --email contact@forgejo.org -d example.com --nginx
