Homelab

This is my homelab set up, it focused on automation to simplify provisioning, upgrading, and operating self-hosted services.

! ⚠️ WORK IN PROGRESS

Overview

Hardware

• 4 nodes of NEC SFF PC-MK26ECZDR (Japanese version of the ThinkCentre M700):
  • CPU: Intel Core i5-6600T @ 2.70GHz
  • RAM: 16GB
  • SSD: 128GB
• TP-Link TL-SG108 switch:
  • Ports: 8
  • Speed: 1000Mbps

Features

Status: Alpha

• Common applications: Gitea, Seafile, Jellyfin, Paperless...
• Automated bare metal provisioning with PXE boot
• Automated Kubernetes installation and management
• Installing and managing applications using GitOps
• Modular architecture, easy to add or remove features/components
• Automated certificate management
• Expose services to the internet securely with Cloudflare Tunnel
• CI/CD platform
• Distributed storage
• Monitoring and alerting
• Support multiple environments (dev, stag, prod)
• Automated offsite backups
• Single sign-on

See Roadmap for more details.
