Things people build with this

USE CASE 1

Follow step-by-step exercises to learn Kubernetes by deploying real workloads rather than reading documentation alone.

USE CASE 2

Use the hellok8s Go sample app to practice deploying, scaling, and managing applications on a Kubernetes cluster.

USE CASE 3

Learn Helm packaging by deploying a complete application using the chart examples in the final lessons.

USE CASE 4

Study Kubernetes secrets, configmaps, and ingress by modifying the example code incrementally across lessons.

Requires a running Kubernetes cluster such as Minikube or Kind and basic familiarity with containers before starting.

In plain English

This repository is a free, open-source Kubernetes tutorial written primarily in Chinese. Kubernetes (often shortened to k8s) is a system used to run and manage containerized applications at scale. The tutorial is aimed at people who want hands-on practice rather than just reading documentation. The course is structured as a progressive series of lessons. It starts with the most basic concept, a container, and then introduces each Kubernetes resource type one at a time: pods, deployments, services, ingress, namespaces, configmaps, secrets, jobs and cronjobs, and finally Helm, which is a tool for packaging and deploying a full application. Each lesson builds on the previous one with gradually modified example code. The README notes that the tutorial assumes you have some familiarity with containers and basic Kubernetes theory beforehand. If you are starting from zero, it recommends reading the official Kubernetes documentation first, then using this tutorial to reinforce that knowledge through practice. The tutorial content is also published on the author's personal website at guangzhengli.com/courses/kubernetes, where the reading experience is described as better than browsing GitHub directly. The repository accepts community contributions through pull requests and issues, and hosts a discussions section for questions. A small Go application called hellok8s is used as the sample workload throughout the lessons.

Copy-paste prompts

Prompt 1

I'm following the k8s-tutorials by guangzhengli. I've set up a basic pod but need help writing a Deployment manifest that scales to 3 replicas with a rolling update strategy.

Prompt 2

Using the hellok8s example app from guangzhengli/k8s-tutorials, show me how to expose it via a Kubernetes Service and Ingress so I can reach it from my browser.

Prompt 3

Help me create a Kubernetes ConfigMap and Secret for the hellok8s app, then mount them as environment variables inside the pod.

Prompt 4

I'm on the Helm lesson in guangzhengli/k8s-tutorials. Show me how to package the hellok8s app as a Helm chart with configurable replica count.

Prompt 5

Walk me through setting up a Kubernetes namespace and deploying hellok8s into it with a dedicated service account.
