GitOps Driven Homelab

This project utilizes Infrastructure as Code and GitOps to automate the provisioning, operation, and updating of self-hosted services in my homelab.

Features

• Automated deployment of all services using ArgoCD
• Automated updates of all services using Renovate
• Automated DNS updates of local DNS (AdGuard Home) using external-dns
• Automated DNS updates of global DNS (Cloudflare) using cert-manager.io
• Automated certificate creation and renewal using cert-manager.io
• Media Server setup using Plex
• Media Automation using Radarr, Sonarr, Lidarr
• Password Management with Vaultwarden
• Kubernetes Native Storage using csi-driver-nfs
• Automated Kubernetes backups using velero
• Automated Database Setup and Backups using CloudNativePG
• Monitoing setup using Grafana, Grafana Loki, Grafana Mimir and Grafana Alloy

Hardware Stack

After nearly a decade with Debian and ZFS, I’ve switched to Unraid for a more power-efficient storage solution. Unlike ZFS, Unraid allows idle disks to spin down, significantly reducing energy consumption while still providing over 100 TB of RAID storage.

My setup consists of a single Unraid server that runs Kubernetes in Talos Linux VMs.
