How can I create a certificate for the container using certbot?

I never used certbot, so I have no idea. The way I would add SSL, is to have a reverse proxy (like Nginx or Caddy) that proxies the http and websocket traffic to port 8006.

If you use a container like Nginx Proxy Manager for example, it is very easy to do with just a few clicks.
