AWS Lightsail Container forwarding to subdomain

I have an AWS Lightsail container service. I will have multiple subdomains. What I want is this: I will have one website name. I want to provide my products as subdomains, but I failed because the container has not a static IP. How can I solve this?

My website name is: emre.com Product 1: prod1.emre.com Product 2: prod2.emre.com

For now, I want it to redirect to prod1.emre.com when someone enters emre.com. I want the user to see prod1.emre.com in their browser. I will change this in the future, but this is the structure I need for now.
