Localhost over https?

[firstdivision]

I there a built-in way to get localhost delivered with a self-signed certificate / https? Or a way to automate that as part of setup?

I saw this part of the example docker-compose.yml and had hoped it was "built-in", but unless I'm missing something it does not appear to be?

ports:
    - 80:80
    - 443:443

I also saw the docs about using certbot, but that will only work on a production / real domain, right?
