Khue's Homelab
Features • Get Started • Documentation
This project utilizes Infrastructure as Code and GitOps to automate provisioning, operating, and updating self-hosted services in my homelab. It can be used as a highly customizable framework to build your own homelab.
What is a homelab?
Homelab is a laboratory at home where you can self-host, experiment with new technologies, practice for certifications, and so on. For more information, please see the r/homelab introduction and the Home Operations Discord community (formerly known as k8s-at-home).
Overview
Project status: ALPHA
This project is still in the experimental stage, and I don't use anything critical on it. Expect breaking changes that may require a complete redeployment. A proper upgrade path is planned for the stable release. More information can be found in the roadmap below.
