ritchie229 — Homelab & DevOps portfolio homelab.int.eu.org (candidate)

Kubernetes • ArgoCD • Jenkins • CI/CD • Monitoring • self-hosting
GitHub
Personal homelab, experiments and documentation for my projects.
This site is the canonical portfolio for my software/devops work — root domain for is-a.dev / EU.org requests. All services run on nested subdomains.

About this homelab

This repository serves as a portfolio and documentation hub for my homelab: deployment manifests, CI pipelines, monitoring dashboards and demo applications. Everything is strictly non-commercial and intended for learning & experimentation.

  • Stack: Docker, Kubernetes (minikube), ArgoCD, Jenkins, Prometheus/Grafana
  • Networking: Cloudflare Tunnel for external access, NodePort for local dev, iptables DNAT for bridging
  • Registry: GHCR (GitHub Container Registry)

Projects & Services

Demo Flask App
Realtime coffee-ordering app (Flask + Socket.IO). Repo & container images linked on GitHub.
CI/CD: Jenkins + ArgoCD
Jenkins builds images and updates manifests → ArgoCD syncs to cluster.
Monitoring
Prometheus server + Alertmanager + Grafana dashboards for cluster & router metrics.
Kubernetes manifests
Kustomize base + overlays for minikube/production, demonstrated with demo app.

Architecture (summary)

High-level: CI builds → GHCR → manifests repo → ArgoCD → minikube. External access provided by Cloudflare Tunnel which proxies hostnames to local ports or to external URLs (hub page).

How subdomains are used:

  • homelab.int.eu.org — hub (this site)
  • jenkins.homelab.int.eu.org — Jenkins (baremetal)
  • grafana.homelab.int.eu.org — Grafana (Docker)
  • k8s-* — NodePort-mapped K8s services via DNAT

Screenshots (placeholders)

Add actual screenshots here (ArgoCD, Jenkins, Grafana, diagram). For PR include at least two screenshots showing DevOps context.

Deploy & Notes for maintainers

If you are a maintainer evaluating this PR — root domain will only serve as portfolio. All self-hosted services will be at nested subdomains. I confirm non-commercial use.

PR description (copy-paste)

This is my personal DevOps portfolio site (Kubernetes, ArgoCD, Jenkins, Docker, monitoring, homelab setup).
Root site will only serve the portfolio; all self-hosted projects will be placed on nested subdomains such as jenkins.homelab.int.eu.org, grafana.homelab.int.eu.org, etc.
