Above you can se an ilustration of my aws environment. Maybe this will help ilustrate the problem.
I have a DEV environment with multiple Beanstalk projects being managed by one Shared Application Load Balancer.
It works great pointing the listeners to each target groups BUT
IF I Rebuild an environment or by any chance AWS kills one of my instances I have to manually re-register that new instance to the respective target group.
Is that any way to do it automatically? I've tried autoscalling groups with no success.
