Tell us about your request
To have an option to reuse an ALB for multiple Ingress via annotation

Which service(s) is this request for?
EKS

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
Currently ALB ingress controller creates an ALB for each ingress object, which can be costly. There are a couple of issues open for the same on other repos i.e. 688 and 298

Are you currently working around this issue?
Using NLB with nginx-ingress, however, NLB doesn't support WAF, which is the use case.

is there ETA for this feature ?

Alternative solution with two ingress controller, alb ingress and nginx ingress.

Nginx will be the target for alb with port 80. And application services running in cluster with different port and namespaces will communicate nginx.

I have documented my solution. I think it will help your requirement.

You can now share a single ALB across multiple Kubernetes ingress objects! This controller release includes a number of other enhancements as well, such as support for fully private EKS clusters. See links below for more details.
