Demo to set SSL properly in NGINX

I've been trying to deploy a GeoNetwork (GN) using the docker-compose on an Azure VM with OAuth authentification, and I have difficulty with the redirect URL.

My current hypothesis is that since we use the default GN image container, it comes in a Jetty image that does not support the HTTPS request nor properly handle the HTTP into HTTPS redirect (as you explained); thus, URLs are not correctly handled.

Is there a way to inject configuration to Jetty in the docker image?

If I want to package my own GN image in a Dockerfile, what do I need?

Is there a way to have an image with an HTTPS Jetty directly from this image repository (in the future) for easier production use?
