Subdomain proxy pass to docker container

I'm looking for a skilled professional who can help me set up a subdomain to forward to a Docker container on my server. I am open to using nginx, but would appreciate your advice on whether it's necessary.

Key Requirements:
- Set up a subdomain to forward to a Docker container
- Evaluate and advise on the necessity of using nginx for this setup

I am keen to get this done ASAP, so prompt and reliable communication is essential.
