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).

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.

• 4 × NEC SFF PC-MK26ECZDR (Japanese version of the ThinkCentre M700):

  • RAM: 16GB
  • SSD: 128GB
• TP-Link TL-SG108 switch:
  • Ports: 8
  • Speed: 1000Mbps

• Common applications: Gitea, Jellyfin, Paperless...
• Automated bare metal provisioning with PXE boot
• Automated Kubernetes installation and management
• Installing and managing applications using GitOps
• Automatic rolling upgrade for OS and Kubernetes
• Automatically update apps (with approval)
• Modular architecture, easy to add or remove features/components
• Automated certificate management
• Automatically update DNS records for exposed services
• VPN without port forwarding
• Expose services to the internet securely with Cloudflare Tunnel
• CI/CD platform
• Private container registry
• Distributed storage
• Support multiple environments (dev, prod)
• Monitoring and alerting
• Automated offsite backups 🚧
• Single sign-on
• Infrastructure testing

Some demo videos and screenshots are shown here. They can't capture all the project's features, but they are sufficient to get a concept of it.
