Olympus

Olympus is both the physical infrastructure I run at home and the code that manages it. The hardware side is a Dell PowerEdge 730XD and a Raspberry Pi cluster. The software side is a Terraform + Ansible pipeline that provisions and configures everything from scratch.

Hardware

• Dell PowerEdge 730XD — the primary server, running Proxmox for virtualization. Handles compute-heavy workloads, storage, and most of the self-hosted services.
• Raspberry Pi Cluster — a set of Pis running lightweight services and edge workloads. Good for things that don't need much power but benefit from being separate from the main server.

What It Runs

The cluster runs Kubernetes for container orchestration, managed with Helm and ArgoCD for GitOps-style deployments. The services running on it are the same tools I use professionally:

• Networking — DNS resolution, ad blocking (Pi-hole), reverse proxy (Traefik), WireGuard VPN
• Databases — PostgreSQL, MySQL, Redis
• Monitoring — Prometheus for metrics collection, Grafana for dashboards, alerting pipelines
• Development — self-hosted Git (Gitea), CI/CD runners, container registry
• Storage — file management, automated backups, media services

Infrastructure as Code

Everything is codified. No machine gets configured by hand.

Terraform handles cloud resource provisioning — VMs, networking, DNS records, storage buckets. State is managed remotely so multiple runs are safe and consistent.

Ansible handles machine configuration — installing packages, hardening security, deploying services, managing users. Every playbook is idempotent, so running it twice produces the same result.

Secrets are managed through encrypted vaults and never committed in plain text.

Why I Run This

It started as a learning project, but it's become genuinely useful. I test infrastructure patterns here before recommending them at work. When I need to try something — a new monitoring setup, a different ingress controller, a database migration strategy — I have a real cluster to experiment on without risking anything in production.
