I have deployed latest version dify in docker in a testing environment.
Now that i want to enable https, however, i don't have any domain nor ca signed certificate as it is just a test environment, so i just generate a self signed certificate.

My question is how to enable https with this self signed certificate?

p.s. I have researched that you can use the certbot as described from
https://github.com/langgenius/dify/blob/141e4e02761801d0b17cd531fa6083cdb22750c1/docker/certbot/README.md to enable https, however, i dont have a domain so it does not work.
