Overview

Kubernetes The Hard Way is an extensive tutorial designed for those who wish to dive deep into understanding Kubernetes from the ground up. Unlike automated tools that simplify the process, this guide takes a more methodical approach, encouraging learners to engage with each step of setting up a Kubernetes cluster manually. While this may not be suited for those seeking a quick setup, it is perfect for individuals eager to grasp the intricate details of Kubernetes fundamentals.

By setting up a basic cluster with a single control plane and two worker nodes, users can explore core concepts thoroughly. Despite not being production-ready and receiving limited community support, the insights gained from this journey can be invaluable for anyone looking to enhance their tech skills in cloud-native environments.
