🧠 Ced’s HomeLab (Enterprise Infrastructure & Monitoring Lab)

A production-style infrastructure lab showcasing real-world systems engineering, monitoring, and platform operations.

This environment functions as a personal datacenter, combining virtualization, Kubernetes orchestration, observability, and secure external access.

🚀 What This Lab Demonstrates

  • Infrastructure design (Proxmox + virtualized services)
  • Kubernetes orchestration (12-node K3s cluster)
  • Network segmentation (VLAN architecture)
  • Monitoring & observability (Grafana, Prometheus, Uptime Kuma)
  • Secure service exposure (Cloudflare Tunnels + reverse proxy)
  • Real-world system integration (data, services, automation)

🔥 Featured Project: SOC Lab

A focused project within this homelab that demonstrates monitoring, logging, and security concepts.

🏗️ Architecture Overview

This lab is built around three core layers:

🖥️ Infrastructure Layer

  • Proxmox VE hypervisor
  • Virtual Machines + LXC containers
  • TrueNAS storage backend (ZFS, NFS, SMB)

☸️ Orchestration Layer

  • 12-node K3s Kubernetes cluster
  • Workload segmentation (ingress, data, monitoring)
  • MetalLB + NGINX ingress

🌐 Access & Networking Layer

  • VLAN segmented network (UDR)
  • Nginx Proxy Manager
  • Cloudflare Tunnel (zero port-forwarding)

🎯 Purpose

This lab is designed to:

  • Simulate production-style environments
  • Build hands-on infrastructure experience
  • Develop monitoring and system visibility skills
  • Serve as a real-world engineering portfolio project

🌐 Network & VLANs

The lab runs behind a UniFi Dream Router (UDR) with VLAN segmentation:

Network Subnet Purpose
Main 10.10.10.0/24 Daily-use devices
MyHomeIOT 10.10.20.0/24 IoT devices, TVs, consoles
HomeLab 10.10.30.0/24 Servers, services, K3s, storage
Guest 10.10.99.0/24 Guest Wi-Fi

The HomeLab VLAN (10.10.30.0/24) hosts all core infrastructure.

🧱 Core Components

🖥️ Proxmox VE

  • Main hypervisor for VMs and LXCs
  • Future expansion to a Proxmox cluster (+5 nodes)
  • Uses TrueNAS for shared storage (NFS / iSCSI)
    📁 See: proxmox/

💾 TrueNAS (ZFS Storage)

  • Manages ZFS pools and datasets
  • NFS exports for Proxmox VM storage
  • SMB / media dataset for Jellyfin & Arr stack
    📁 See: truenas/

☸️ K3s Raspberry Pi Cluster

A 12-node K3s cluster built on Raspberry Pi hardware for orchestrating containerized workloads across the lab.

Current and planned uses include:

  • Containerized applications
  • Ingress-based routing
  • Monitoring workloads
  • Future GitOps and Helm-based deployments

📌 Full cluster repo:
https://github.com/ced4568/ced-k3s-homelab

🌐 Reverse Proxy & Cloudflare Tunnel

  • Nginx Proxy Manager (NPM)
  • Cloudflare Tunnel (no port forwarding)
  • Wildcard DNS: *.cedshomelab.com

Traffic Flow: Internet → Cloudflare Edge → Tunnel → NPM → Internal Services

📁 Docs: docs/Add_New_Service_Guide.md

🏠 Home Automation

  • Home Assistant (Proxmox VM)
  • IoT isolated on MyHomeIOT VLAN
  • Secure access via Cloudflare + NPM
  • trusted_proxies configured

📁 Config: home-assistant/

📊 Observability (Ced’s NOC)

The lab includes an observability stack built around:

  • Prometheus for metrics collection
  • Grafana for dashboards and visualization
  • Uptime Kuma for service-level monitoring

Current and planned monitoring coverage includes:

  • Proxmox performance
  • K3s cluster health
  • Service uptime
  • Infrastructure visibility improvements over time

📁 See: monitoring/

📊 Live NOC & Automation Pipeline

The homelab powers a public-facing live NOC dashboard at noc.chasedumphord.com.

An automated Python script runs on Biggie (Proxmox node 10.10.30.192) every 5 minutes via cron. It pings all 28 systems, records latency and online/offline status, writes a structured JSON file, and pushes it to GitHub. The dashboard updates automatically.

Biggie (10.10.30.192) — cron: */5 * * * *
  → noc_update.py
    → ICMP ping 28 systems
    → record latency + status
    → write data/noc-status.json
    → git commit + push to ced-portfolio
      → GitHub Pages deploys (~30s)
        → noc.chasedumphord.com auto-refreshes
