I have servers running in AWS Application Load Balancer.
The AWS Load Balancer can only be connected to via an A-name (I.e. "prod-LB-us-west-2.elb.amazonaws.com"). A fun catch with AWS laod balancers is: the IP address will not remain consistent. It can (and does) change randomly. So I can't just point the A-record to the Load Balancer's IP.
The PM wants EVERYTHING hitting the domain to go to the correlated port on the Load Balancer: I.e.
example.com:3000 -> prod-LB-us-west-2.elb.amazonaws.com:3000
example.com:3001 -> prod-LB-us-west-2.elb.amazonaws.com:3001
Can this be done with a wildcard'ed cname?
If not, I'm not sure how to forward each name resolution to the Load Balancer.
