wtf is kubernetes-handbook?

This repository contains a comprehensive Chinese-language handbook on Kubernetes and cloud-native technologies, written by Jimmy Song (also known online as rootsongjc). The project started in 2016 and was open-sourced in 2017, making it one of the earliest systematic Chinese-language books on Kubernetes. It has been updated continuously since then and currently covers Kubernetes v1.31 and later. Kubernetes is a system originally built by Google to manage containerized applications across clusters of machines. Instead of manually deciding which server runs which piece of software, Kubernetes lets you describe what you want to run, and the system figures out placement, restarts failed containers, scales up when load increases, and keeps things running according to your specification. This handbook explains those concepts in depth, starting from the basics and progressing to more advanced topics. Beyond core Kubernetes, the book covers the broader cloud-native landscape: service meshes (such as Istio, which handles communication and security between microservices), Serverless computing, DevOps practices, edge computing, and what the author calls AI-native infrastructure. The writing is oriented toward practical experience and best practices rather than purely theoretical explanations. The book is freely readable online at jimmysong.io and on GitHub, and PDF downloads are available from the releases page.
