Hello,  
I am using traefik as a proxy inside a docker container and would like to set my own custom default cert(it is not generated by letsencrypt). I read the documentation at [https tls docs](https://doc.traefik.io/traefik/https/tls/) and it seems I need to edit the config file. I tried locating the config file inside the container but I can't to find it searching traefik just gives me the location of the binary.  
I wonder if there is an easier way to do it when using docker compose. I am using the traefik:2.5 docker image. Thank you.

Why would you use an outdated Traefik version, when current is v2.10 ?

You can declare a default TLS cert in a dynamic config file, which you need to load with `provider.file` in static config. ([Doc](https://doc.traefik.io/traefik/https/tls/#default-certificate))
