🪨 Homelab 🏡

Repository for home infrastructure and Kubernetes cluster using GitOps practices.

Held together using Proxmox VE, OpenTofu, Talos, Kubernetes, Argo CD and copious amounts of YAML with some help from Renovate.

---

📖 Overview

This repository hosts the IaC (Infrastructure as Code) configuration for my homelab.

The Homelab is backed by Proxmox VE hypervisor nodes with VMs bootstrapped using OpenTofu/Terraform.

Most of the services run on Talos flavoured Kubernetes, though I'm also running a TrueNAS VM for storage and Home Assistant VM for home automation.

To organise all the configuration I've opted for an approach using Kustomized Helm with Argo CD which I've explained in more detail in this article.

I journal my homelab journey over at my self-hosted blog.

🧑‍💻 Getting Started

If you're new to Kubernetes I've written a fairly thorough guide on Bootstrapping k3s with Cilium. In the article I try to guide you from a fresh Debian 12 Bookworm install to a working cluster using the k3s flavour of Kubernetes with Cilium as a CNI and IngressController.

I've also written an article on how to get started with Kubernetes on Proxmox if virtualisation is more your thing.

I'm currently working on an article on how to bootstrap your own Talos-cluster using this repo.

⚙️ Core Components

• Proxmox VE: Server management and KVM hypervisor.
• OpenTofu: Open source infrastructure as code tool.
• Cilium: eBPF-based Networking, Observability, Security.
• Argo CD: Declarative, GitOps continuous delivery tool for Kubernetes.
• Cert-manager: Cloud native certificate management.
• Sealed-secrets: Encrypt your Secret into a SealedSecret, which is safe to store - even inside a public repository.
