title: Admin Guide

|
||||
|
||||
The cluster admin guide is for anyone creating or administering a Kubernetes cluster.
|
||||
It assumes some familiarity with concepts in the [User Guide](/docs/user-guide/).

## Planning a cluster
|
||||
|
||||
There are many different examples of how to setup a Kubernetes cluster. Many of them are listed in this
|
||||
[matrix](/docs/getting-started-guides/). We call each of the combinations in this matrix a *distro*.
|
||||
|
||||
Before choosing a particular guide, here are some things to consider:
|
||||
|
||||
- Are you just looking to try out Kubernetes on your laptop, or build a high-availability many-node cluster? Both
|
||||
models are supported, but some distros are better for one case or the other.
|
||||
- Will you be using a hosted Kubernetes cluster, such as [GKE](https://cloud.google.com/container-engine), or setting
|
||||
one up yourself?
|
||||
- Will your cluster be on-premises, or in the cloud (IaaS)? Kubernetes does not directly support hybrid clusters. We
|
||||
recommend setting up multiple clusters rather than spanning distant locations.
|
||||
- Will you be running Kubernetes on "bare metal" or virtual machines? Kubernetes supports both, via different distros.
|
||||
- Do you just want to run a cluster, or do you expect to do active development of Kubernetes project code? If the
|
||||
latter, it is better to pick a distro actively used by other developers. Some distros only use binary releases, but
|
||||
offer is a greater variety of choices.
|
||||
- Not all distros are maintained as actively. Prefer ones which are listed as tested on a more recent version of
|
||||
Kubernetes.
|
||||
- If you are configuring Kubernetes on-premises, you will need to consider what [networking
|
||||
model](/docs/admin/networking) fits best.
|
||||
- If you are designing for very high-availability, you may want [clusters in multiple zones](/docs/admin/multi-cluster).
|
||||
- You may want to familiarize yourself with the various
|
||||
[components](/docs/admin/cluster-components) needed to run a cluster.
|
||||
|
||||
## Setting up a cluster
|
||||
|
||||
Pick one of the Getting Started Guides from the [matrix](/docs/getting-started-guides/) and follow it.
|
||||
If none of the Getting Started Guides fits, you may want to pull ideas from several of the guides.
|
||||
|
||||
One option for custom networking is *OpenVSwitch GRE/VxLAN networking* ([ovs-networking.md](/docs/admin/ovs-networking)), which
|
||||
uses OpenVSwitch to set up networking between pods across
|
||||
Kubernetes nodes.
|
||||
|
||||
If you are modifying an existing guide which uses Salt, this document explains [how Salt is used in the Kubernetes
|
||||
project](/docs/admin/salt).
