## What it is
A living educational document explaining the full lifecycle of a kubectl request through Kubernetes internals, from client validation to kubelet container startup. It links to Kubernetes source code to illustrate each stage of the request path.

## Use cases
- understand what happens when I run kubectl create deployment
- learn how the Kubernetes scheduler assigns pods to nodes
- study how kube-apiserver handles authentication and admission control
- prepare for a Kubernetes internals interview
- understand how kubelet and CRI start containers
- learn how etcd stores cluster state

## When to choose
- you want a guided, source-linked walkthrough of Kubernetes request flow
- you're learning Kubernetes internals for the first time
- you want to understand the path from kubectl to running pods

## When to avoid
- you need official, version-specific Kubernetes documentation
- you want hands-on operational tooling rather than conceptual explanation
- you need up-to-date coverage of the latest Kubernetes features

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: tutorials, cloud-computing
- platform: cloud
- tags: kubernetes-internals, educational-guide, kubectl, kube-apiserver, kubelet, scheduler, container-orchestration, containers, devops, kubernetes, linux
