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!
