Redirect using 302 status so that there is a future opportunity to reinstate the page or something like it. - Avoid links to removed cluster management task - Broaden applicability of “Safely Drain A Node” - Add (stub) cluster upgrade task page - Add a basic page about upgrading your cluster. - Add a task page about enabling or disabling HTTP APIs

100 | concept | Lower-level detail relevant to creating or administering a Kubernetes cluster. | true |
The cluster administration overview is for anyone creating or administering a Kubernetes cluster. It assumes some familiarity with core Kubernetes concepts.
Planning a cluster
See the guides in Setup for examples of how to plan, set up, and configure Kubernetes clusters. The solutions listed in this article are called distros.
{{< note >}} Not all distros are actively maintained. Choose distros which have been tested with a recent version of Kubernetes. {{< /note >}}
Before choosing a guide, here are some considerations:
- Do you just want to try out Kubernetes on your computer, or do you want to build a high-availability, multi-node cluster? Choose distros best suited for your needs.
- Will you be using a hosted Kubernetes cluster, such as Google Kubernetes Engine, or hosting your own cluster?
- Will your cluster be on-premises, or in the cloud (IaaS)? Kubernetes does not directly support hybrid clusters. Instead, you can set up multiple clusters.
- If you are configuring Kubernetes on-premises, consider which networking model fits best.
- Will you be running Kubernetes on "bare metal" hardware or on virtual machines (VMs)?
- Do you just want to run a cluster, or do you expect to do active development of Kubernetes project code? If the latter, choose an actively-developed distro. Some distros only use binary releases, but offer a greater variety of choices.
- Familiarize yourself with the components needed to run a cluster.
