Tell us about your request

When creating an EKS managed node group, one should be able to set a list of LB target groups which the populated nodes would attach to. At the moment, one has to figure out which autoscaling group has been created for the managed node group and edit it to set the desired target groups. I guess this is an unsupported operation and that it could break if a new autoscaling group is created for the node group (node groups' resources.autoScalingGroups attribute being a list hints me that it could happen).

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?

We've a node group dedicated to ingress controllers which we'd like to attach to two target groups (http and https) which are the destination of the two listeners (tcp 80 and tcp 443) of our internet facing NLB.

Are you currently working around this issue?

At the moment, we manually edit the generated autoscaling group to attach the target groups, but we suspect this is a fragile setup and we can't rely on a fragile setup for such a critical part of our cluster.
