I am working on creating an ALB for 2 services together, with the annotation : merged. It's not working out. I can't see much action in logs as well. What am I doing wrong? Worker nodes have the ALB ingress policy as mentioned in AWS docs(adding the policy below as well). Kubernetes is not complaining, but ingress-service is not getting an Address, and no ALB or target group is getting created.

kubectl get ingress
NAME HOSTS ADDRESS PORTS AGE
auth-ingress host.domain.com,sub-domain.host.domain.com 80 6sAs you can see, there is no address available.
As per this currently the ALB ingress controller cretaes new ALB for each ingress meaning there is no merge support.
Install the merge ingress controller and remove the annotationkubernetes.io/ingress.class: alb
Also make sure to install the ALB ingress controller on the cluster.
