More info/docs here: https://cloud.google.com/container-engine/ I'm on the Kubernetes/GKE team and happy to answer any questions you all might have. We also all hang out on IRC at #google-containers on freenode.

Do you see this being useful for analytical workloads (ie i need a bunch of cores for a short time to run a parallel job) or more focused on scaling web apps and services?

My biggest question on Docker / k8s: How does one control where persistent data lives and the required performance characteristics? Example: I need SSD + a certain level of availability? Is there a good strategy for managing this?

Right now, it isn't plumbed in but it is on the roadmap.

Either (a) you have network based block device and the master/manager maps that to a machine dynamically as the container get scheduled or (b) you constrain the containers to machines that have the hardware/data you need.

(b) is less than ideal but sometimes necessary.

I'm kind of confused. I get that they run on the Google VMs (which need a base OS, yes?) so does this manage all of that? Can I:

pick my vm size/ pick my docker image/ and go?

AKA does this bring me one step closer to docker-oku-aaS?

It can be used as both. As we build out better resource isolation and QoS, you'll be able to run mixed workload on the same hardware/VMs and use "every part of the animal".

Essentially that is the case.

If you just want to launch a static set of containers on a specific VM, you can use our Container VM image -- https://cloud.google.com/compute/docs/containers/container_v....

Kubernetes (and GKE) is a dynamic system to run across a cluster of machines.

Is it possible to run a KVM VM inside one of the containers? I have an application for launching and managing VMs and letting people spin up a Google container to try it out would be neat.

GCE doesn't support nested virtualization.

But if you are running Kubernetes on bare metal, there is no reason you couldn't map in /dev/kvm and have k8s run VMs for you. I haven't done it though :)
