Static External IP (AWS elastic IP)

[Vadim-Zenin]

Is your feature request related to a problem?
We need static external IP for AWS load-balancer.

Describe the solution you'd like
Would be nice if we could assign reserved AWS elastic IPs to the load-balancer.

Hello, thanks for reporting this. Can you please clarify if this is referring to an ALB or NLB? Thank you.

[Vadim-Zenin]

Ideally would be for both ALB and NLB, like Internet <-> AWS NLB with elastic IP <-> AWS ALB <-> AWS EKS.
Minimum for NLB, like Internet <-> AWS NLB with elastic IP <-> AWS EKS.
Would be nice keep user's IP info...
P.S. AWS ALB does not support static IP even customers request it since many years ago. You could suggest any reasonable work around.

Unfortunately we have not added support for ALB as a target of NLB (#2297).

Like you mention, NLB does support choosing the IP, and the controller supports it to. https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.10/guide/service/annotations/#eip-allocations

A solution to your problem is to set up an out of band NLB, have the LBC manage an ALB, and manually register the ALB into your NLB. This should be reasonably straight forward as you shouldn't need to manage the out of band NLB, while the LBC will do the heavy lifting of ensuring the ALB targets are correctly updated.
