+1 Although longer term we should enable the AWS cloudprovider routes feature (https://github.com/kubernetes/kubernetes/blob/071d21257fdfd439a9286fffbd5972c85643cd49/pkg/cloudprovider/providers/aws/aws_routes.go) and make the subnets fully configurable. |

I don't want to change the defaults until all fields are configurable. This needs to land after #190 |
|
I would not recommend changing the default address anyway. At least not until kubernetes properly supports it. |
|
We are going to make this configurable for folks that don't need to rely on the portions of Kubernetes hard-coded to 10.0.0.0/8: #190. Please interface with the upstream community to address the issues preventing us from using a range outside of 10.0.0.0/8 if you believe it is important. |
10.0.0.0/14 is really really popular for folks to already have in their infrastructure. If one wanted to vpc peer to the kubernetes cluster, it would be difficult with 10.0.0.0/14. 172.20.0.0/14 is probably less popular & more likely to just work.
Creating this patch shows that we need a way to have these network IP addresses & CIDRs as cluster.yaml settings & not hard coded into go & misc files. I will make sure there's an issue for this concern.
