Kubernetes
Kubernetes is an open source implementation of container cluster management.
Kubernetes Design Document - Kubernetes @ Google I/O 2014
Kubernetes can run anywhere!
However, initial development was done on GCE and so our instructions and scripts are built around that. If you make it work on other infrastructure please let us know and contribute instructions/code.
Kubernetes is in pre-production beta!
While the concepts and architecture in Kubernetes represent years of experience designing and building large scale cluster manager at Google, the Kubernetes project is still under heavy development. Expect bugs, design and API changes as we bring it to a stable, production product over the coming year.

Community, discussion and support
If you have questions or want to start contributing please reach out. We don't bite!
The Kubernetes team is hanging out on IRC on the #google-containers channel on freenode.net. We also have the google-containers Google Groups mailing list for questions and discussion as well as the kubernetes-announce mailing list for important announcements (low-traffic, no chatter).
If you are a company and are looking for a more formal engagement with Google around Kubernetes and containers at Google as a whole, please fill out this form and we'll be in touch.
