Hi all,

I'm building a K8s cluster with KOps. With 3 IGs, one in each AZ. Nodes are 
automatically tagged with failure-domain tags - 
e.g.```failure-domain.beta.kubernetes.io/region=us-east-1,failure-domain.beta.kubernetes.io/zone=us-east-1a```
 and so for each AZ.
I'v added the cluster-autoscaler with auto discovery based on:
https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/cloudprovider/aws/examples/cluster-autoscaler-autodiscover.yaml

then created a few hundreds of dummy containers just to see it scale out, but 
once it started scaling up the underlying ASG, it was completely uneven (one 
ASG went to maximum and one other was added a couple of nodes, while the third 
did nothing). Pods were distributed accordingly (this is a new cluster so 
nothing else runs there).

I've being reading documentation and from what I understand this should be 
"just working"... Can someone help me understand what am I doing wrong or 
direct me to a comprehensive example I can try out?

Best,
Arik
