Production Kubernetes Homelab
Enterprise-grade Kubernetes infrastructure on Raspberry Pi 5 with advanced monitoring, auto-scaling, security hardening, and DevOps automation. Featuring 16% memory optimization, multi-metric HPA, and comprehensive observability stack.
Production Achievements & Architecture
Production-Grade Kubernetes Architecture
Built a complete K3s cluster on Raspberry Pi 5 with enterprise-grade monitoring and Infrastructure as Code using Kustomize overlays and Helm charts. Designed multi-tier architecture with proper separation of concerns for monitoring, applications, and ingress.
Advanced Monitoring & Observability Stack
Deployed Prometheus + Grafana with custom dashboards and alerting. Implemented custom metrics collection for Minecraft server (player count, TPS, performance) and comprehensive monitoring covering cluster health, application metrics, and resource utilization.
Sophisticated Auto-Scaling Implementation
Built HPA (Horizontal Pod Autoscaler) with multi-metric scaling (CPU, memory, custom metrics). Implemented intelligent scaling policies with aggressive scale-up and conservative scale-down. Custom metrics integration - scaling based on Minecraft player count.
Security-First Approach & DevOps Automation
Implemented comprehensive security analysis with detailed risk assessment, container security best practices, network policies and RBAC configurations. Created comprehensive Makefile with automated deployment pipelines and backup automation with CronJobs.
Advanced Application Deployment
Minecraft server with production features: health checks (liveness, readiness, startup probes), resource management (CPU/memory requests and limits), persistent storage with automated backups, and custom metrics exporter integration.
Virtualization & Multi-Tenancy
Deployed 3-tier LAMP architecture using VMs in containers. Built interactive port-forwarding scripts with user-friendly menus and created educational lab environments for hands-on learning with proper isolation.
