Kubernetes is an open source system for managing containerized applications
With the 1.0.1 release Kubernetes is ready to serve your production workloads.
Kubernetes can run anywhere!
You can run Kubernetes on your local workstation under Vagrant, cloud providers (e.g. GCE, AWS, Azure), and physical hardware. Essentially, anywhere Linux runs you can run Kubernetes. Checkout the Getting Started Guides for details.
Kubernetes works with the following concepts:
Cluster : A cluster is a set of physical or virtual machines and other infrastructure resources used by Kubernetes to run your applications. Kubernetes can run anywhere! See the Getting Started Guides for instructions for a variety of services.
Node : A node is a physical or virtual machine running Kubernetes, onto which pods can be scheduled.
Pod : Pods are a colocated group of application containers with shared volumes. They're the smallest deployable units that can be created, scheduled, and managed with Kubernetes. Pods can be created individually, but it's recommended that you use a replication controller even if creating a single pod.
Replication controller : Replication controllers manage the lifecycle of pods. They ensure that a specified number of pods are running at any given time, by creating or killing pods as required.
Service : Services provide a single, stable name and address for a set of pods. They act as basic load balancers.
Label : Labels are used to organize and select groups of objects based on key:value pairs.
Kubernetes documentation is organized into several categories.
