How do I point a domain to an IP address and port?

I'm familiar with setting up websites with Baidu Yuntong, of course.

Now, I'm learning to deploy sites with Docker. After successfully running, my site is accessible at an IP and port (e.g., 24.28.29.333:8080).

How can I bind this to a domain so I can access it via my domain name?

And if I have multiple sites on one VPS, what's the process?

Thank you.
