This is my homelab infrastructure, defined in code.

📖 Overview

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

Most of my homelab runs on Proxmox, with VMs managed and maintained using OpenTofu. All VMs are cloned from templates I created with Packer.

All services are containerized, either managed with Docker Compose or orchestrated with Kubernetes (K3s). Over time, I’ve been migrating everything to Kubernetes using GitOps practices, which is my long-term goal.

To automate infrastructure updates, I use Forgejo Actions, which trigger workflows upon changes to this repo. This ensures seamless deployment and maintenance across my homelab:

• Flux manages Continuous Deployment (CD) for Kubernetes, bootstrapped via OpenTofu.
• Docker CD Workflow handles Continuous Deployment for Docker services.
• Renovate keeps services updated by opening PRs for new versions.
• Yamllint ensures configuration files are properly structured.
• Ansible is used to execute playbooks on all of my VMs, automating management and configurations

🔒 Security & Networking

For Secret management I use Bitwarden Secrets and their various integrations into the tools used.

Kubernetes is using SOPS with Age encryption until migration over to Bitwarden Secrets.

I use Oracle Cloud for their Always-Free VM's and deploy Docker services that require uptime here (Uptime Kuma, this website). Twingate is used to connect my home network to the various VPS's securely using Zero Trust architecture.

I use Cloudflare for my DNS provider with Cloudflare Tunnels to expose some of the services to the world. Cloudflare Access is used to restrict the access to some of the services, this is paired with Fail2Ban looking through all my reverse proxy logs for malicious actors who made it through Access and banning them via Cloudflare WAF.

For my home network I use PfSense with VLAN segmentation and strict firewall rules to isolate public-facing machines, ensuring they can only communicate with the necessary services and nothing else.

📊 Monitoring & Observability

I use a combination of Grafana, Loki, and Prometheus with various exporters to collect and visualize system metrics, logs, and alerts. This helps maintain visibility into my infrastructure and detect issues proactively.

• Prometheus – Metrics collection and alerting
• Loki – Centralized logging for containers and VMs
• Grafana – Dashboarding and visualization
• Exporters – Node Exporter, cAdvisor, Blackbox Exporter, etc.

🧑‍💻 Getting Started

This repo is not structured like a project you can easily replicate. Although if you are new to any of the tools used I encourage you to read through the directories that make up each tool to see how I am using them.

Over time I will try to add more detailed instructions in each directories README.

• Kubernetes Secrets with SOPS
• Packer with Proxmox
• Terraform with Proxmox
