I'm trying to create an AWS Autoscaling Group that is fronted by an Application Load Balancer (ALB).

So I begin by creating the Autoscaling Group and after a few screens it allows me to select whether or not I want an ALB. If I select ALB, then it presents me the UI for creating an ALB. The problem is when you get to selecting the Target Group, which is not optional.

My understanding of the Target Group is the pool of resources to forward traffic onto. So in this case, it would be the Autoscaling Group.

So its a Catch-22 here. You can't create the ALB without the Target Group (the Autoscaling Group). And you can't create an ALB-fronted Autoscaling Group without the ALB. So what's the solution here?

The solution is:

1. Create a target group
2. Create an ALB
3. Create the ASG
