Next, you'll need to generate your certificates in the ssl folder, this folder will be mounted in the container and used by NGINX.

In the root of this folder, run:

mkdir ./ssl
openssl req -x509 -nodes -days 5000 -newkey rsa:2048 -keyout ./ssl/server.key -out ./ssl/server.crt

Just follow the instructions, fill in the information as desired.
