Docker setup guide needed

What is the improvement or update you wish to see?

Hello,
I spend hours to get auth.js v5 working in docker environment.
After numerous searches, I found a thread where "NEXTAUTH_URL_INTERNAL" was mentioned and that did the trick.
Problem is that the next app in the docker container still has host localhost:3000, even in production in kubernetes.
Without this env var set to http://localhost:3000, it was not working and just failing with a non helpful error message.

would be nice to have docs about this for others.
kind regards

PS: it's a bit strange that this is the only env var that is still prefixed with NEXTAUTH_ instead of AUTH_

Is there any context that might help us understand?

next running inside docker
keycloak provider
next 14.2.3
next-auth 5.0.0-beta.16

Does the docs page already exist? Please link to it.
