The certificates can be renewed with `certbot renew` but beware to copy the certificates after that.
Instead of copying the certificates, you may wish to mount `/etc/letsencrypt` in the Docker image as a volume (*eg.*`/etc/letsencrypt:/etc/nginx/ssl`).
On certificate renewal (with `certbot`), you then need to restart the Nginx server.
If necessary, in `docker-compose.yml`, update `nginx.volumes`, line `./vidjil-client/ssl:/etc/nginx/ssl`, to set the directory with the certificates.
