Install, operate, and manage the full lifecycle of Kubernetes clusters on machines you already own — through a web console, an API, and a single command.

Welcome to KubeClipper: Convenient Kubernetes Lifecycle Management.

KubeClipper is a lightweight CNCF Sandbox project that takes the hardest part of running Kubernetes — standing clusters up and keeping them healthy over time — and turns it into a guided experience. Rather than asking you to learn kubeadm, wire together a container runtime, and script every node operation by hand, KubeClipper installs itself on a single host with one command, then lets you create conformant Kubernetes clusters on existing bare-metal, virtual, or cloud machines through a friendly web console or its API. Once a cluster exists, the same platform manages its whole life: adding and removing nodes, upgrading versions, backing up and restoring etcd, opening a terminal into any node, and installing plugins. This book explains the problem KubeClipper solves and the philosophy behind it, walks through its kc-server and kc-agent architecture and the NATS message bus that connects them, shows how clusters are described and built from operations and steps, covers day-two work like scaling, upgrades, and backup and restore, explains access control and high availability, and closes with how KubeClipper fits among the other cluster-management tools in the cloud-native world. By the end you will understand not just how to drive KubeClipper but why it is shaped the way it is.
