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.

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.

The current iteration of my homelab runs on Talos Kubernetes and is set up according to this article.

• Proxmox VE: Server management and KVM hypervisor.
• OpenTofu: Open source infrastructure as code tool.
• Cilium: eBPF-based Networking, Observability, Security.
• Proxmox CSI Plugin: CSI driver for storage
• 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.
• Keycloak: Open source identity and access management
• Gateway API: Next generation of Kubernetes Ingress
• AdGuardHome: Domain name server backed by Unbound
• Netbird: Completely self hosted VPN solution
