# Kubernetes The Hard Way
This tutorial walks you through setting up Kubernetes the hard way. This guide is not for someone looking for a fully automated tool to bring up a Kubernetes cluster. Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.
> The results of this tutorial should not be viewed as production ready, and may receive limited support from the community, but don't let that stop you from learning!

## Target Audience
The target audience for this tutorial is someone who wants to understand the fundamentals of Kubernetes and how the core components fit together.
## Cluster Details
Kubernetes The Hard Way guides you through bootstrapping a basic Kubernetes cluster with all control plane components running on a single node, and two worker nodes, which is enough to learn the core concepts.
Component versions:
* [kubernetes](https://github.com/kubernetes/kubernetes) v1.32.x
* [containerd](https://github.com/containerd/containerd) v2.1.x
* [cni](https://github.com/containernetworking/cni) v1.6.x
* [etcd](https://github.com/etcd-io/etcd) v3.6.x
## Labs
This tutorial requires four (4) ARM64 or AMD64 based virtual or physical machines connected to the same network.
