How can I use external certificate files?

Hi!
Is it possible to use external certificate file for Snikket?
Right now it is problematic to obtain LetsEncrypt certificates for the website in Russia: HTTP-01 challenge always fails.
This means Snikket never leaves "Snikket is starting - you have a certificate problem" page.
Because of that I had to obtain my certificate using DNS-01 challenge.

Perhaps it is possible to alter docker-compose.yml somehow to put the privkey.pem and fullchain.pem files inside the containers?

Yes, it is possible.
All .pem files go into /etc/ssl/certbot folder (or /etc/ssl/certbot/SITENAME, I'm not sure, I did both) inside snikket-certs container. Then restart.

It would be wonderful, if this could be mentioned in the documentation.
Anyway, thanks!
