Need help on Docker + HUGO stuff

Well, I’m new to hugo and have been able to deploy it to GitHub without a problem. However, reasonably would like to make static pages for several websites on Linux Debian.

I create my web on macOS running arm M1 + with themes. This is done without any problems.
Uploaded everything to GitLab also without problems.

Now trying to deploy it to my Debian Server with docker running. This is where I got stuck.
Unsure on how to solve it. The docker-compose that I created seems to build the pages correctly, however, I cant make it run. It’s just shown blank white pages.

Trying to use NGINX to run the public HTML without any luck because HUGO seems to build everything on XML? Can someone give me some light on how to make it run?
