For instance, if we see that our worker cluster is has reached some consumed capacity threshold (CPU, memory, etc) then we need to add more worker nodes. The way we do this is via Auto Scaling Groups. Auto Scaling Groups work on launch configs that are essentially an AMI and instance user data. Getting an AMI that just has the Kubernetes stuff that can be started at will and told to join clusters at runtime has not been clear from the documentation I've read.
