Configuring for HTTPS w/ Private Key using Docker Compose

[CarpFlop]

I am attempting to configure DefectDojo to use HTTPS with Docker Compose by following the provided tutorial on the website:
https://github.com/DefectDojo/django-DefectDojo/blob/master/readme-docs/DOCKER.md#run-with-docker-compose-using-https

The question I have and the primary problem I'm running into is that it makes no mention of how to account for private keys with passwords.

I have a signed certificate and private key in PEM(OpenSSL) format, however they required the creation of an associated password.

Assuming there is no alternative and the private key I generate will require a password, how can I implement this following the provided guide as closely as possible?

You can just add the password as another file ex: pass_file and place it alongside the .crt and .key files
