Autoscaling in Google Container Engine

Question

I understand the Container Engine is currently on alpha and not yet complete.

As we work towards a Beta release, we're definitely looking at integrating the Google Compute Engine AutoScaler.

There are actually two different kinds of scaling:

1. Scaling up/down the number of worker nodes in the cluster depending on # of containers in the cluster
2. Scaling pods up and down.

Since Kubernetes is an OSS project as well, we'd also like to add a Kubernetes native autoscaler that can scale replication controllers. It's definitely something that's on the roadmap. I expect we will actually have multiple autoscaler implementations, since it can be very application specific...
