Kubernetes is an open source system for managing [containerized applications](http://kubernetes.io/docs/whatisk8s/) across multiple hosts,
17
+
providing basic mechanisms for deployment, maintenance, and scaling of applications. Kubernetes is hosted by the Cloud Native Computing Foundation ([CNCF](https://www.cncf.io))
Kubernetes builds upon a [decade and a half of experience at Google running production workloads at scale](https://research.google.com/pubs/pub43438.html), combined with best-of-breed ideas and practices from the community.

### Kubernetes is ready for Production !
31
+
32
+
Since the Kubernetes 1.0 release in July 2015 Kubernetes is ready for your production workloads. Check the [case studies](http://kubernetes.io/case-studies/).
33
+
34
+
### Kubernetes can run anywhere !
35
+
36
+
You can run Kubernetes on your local workstation, cloud providers (e.g. GCE, AWS, Azure), on-premises virtual machines and physical hardware. Essentially, anywhere Linux runs you can run Kubernetes. Checkout the [deployment solutions](http://kubernetes.io/docs/getting-started-guides/) for details.

###Kubernetes can run anywhere!
47

The Kubernetes community abides by the CNCF [code of conduct](https://github.com/cncf/foundation/blob/master/code-of-conduct.md). Here is an excerpt:

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](http://kubernetes.io/docs/getting-started-guides/) for details.

_As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities._

## Concepts Overview

Kubernetes works with the following concepts:
44
54
45
-
[**Cluster**](docs/admin/README.md)
46
-
: 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](docs/getting-started-guides/) for instructions for a variety of services.
55

[**Cluster**](http://kubernetes.io/docs/admin/)

[**Node**](docs/admin/node.md)
58
+
[**Node**](http://kubernetes.io/docs/admin/node/)
49
59
: A node is a physical or virtual machine running Kubernetes, onto which pods can be scheduled.
: 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.
: Labels are used to organize and select groups of objects based on key:value pairs.

Do you want to help " shape the evolution of technologies that are container packaged, dynamically scheduled and microservices oriented? ". If you are a company, you should consider joining the [CNCF](https://cncf.io/about).

### Code of conduct
114
-
115
-
Participation in the Kubernetes community is governed by the [Kubernetes Code of Conduct](code-of-conduct.md).
If you're interested in being a contributor and want to get involved in developing Kubernetes, start in the [Kubernetes Developer Guide](docs/devel/README.md) and also review the [contributor guidelines](CONTRIBUTING.md).
Or, if you just have an idea for a new feature, see the [Kubernetes Features](https://github.com/kubernetes/features) repository for details on how to propose it.
96
+
Join a Special Interest Group ([SIG](https://github.com/kubernetes/community))
137
97
138
-
Also, please see our [expectations](docs/devel/community-expectations.md) for members of
139

-
While there are many different channels that you can use to get ahold of us, you can help make sure that we are efficient in getting you the help that you need.
102
+
* The community [expectations](docs/devel/community-expectations.md)
103
+
* The [contributor guidelines](CONTRIBUTING.md)
104
+
* The [Kubernetes Developer Guide](docs/devel/README.md)
144
105
145
-
If you need support, start with the [troubleshooting guide](docs/troubleshooting.md#getting-help) and work your way through the process that we've outlined.
106
+
You will then most certainly gain a lot from joining a [SIG](https://github.com/kubernetes/community), attending the regular hangouts as well as the community [meeting](https://github.com/kubernetes/community/blob/master/community/README.md).
