## What it is
A step-by-step tutorial that walks learners through manually bootstrapping a Kubernetes cluster from scratch, with no automation scripts. It is optimized for understanding how Kubernetes core components like etcd, the control plane, and worker nodes fit together.

## Use cases
- learn how kubernetes works under the hood
- manually bootstrap a kubernetes cluster step by step
- understand kubernetes control plane components
- generate TLS certificates for a kubernetes cluster
- set up etcd and containerd for kubernetes
- study for kubernetes administrator certification
- understand how kubeadm and managed clusters work internally

## When to choose
- you want deep understanding of Kubernetes internals rather than a quick cluster
- you are preparing for CKA or similar Kubernetes certifications
- you learn best by doing each step manually
- you want to see how certificates, etcd, and control plane components connect

## When to avoid
- you need a production-ready cluster quickly
- you want automated cluster provisioning with tools like kubeadm, kops, or a managed service
- you need community support for the resulting cluster
- you only have a single machine and cannot provision several VMs
