A practical guide to running automated vulnerability scanning for Docker containers in your homelab — install Trivy, scan images for CVEs and secrets, set up systemd timers for weekly scans, and integrate with dashboards for actionable security reports.
A practical guide to ZFS pool design and performance tuning for Proxmox homelabs — topology selection, ashift, recordsize, compression, ARC sizing, and real-world monitoring with arcstat and zpool iostat.
A practical guide to diagnosing and fixing Docker container networking problems — DNS timeouts, port conflicts, bridge network isolation, cross-host communication, and the netshoot toolkit for homelab deployments.
A practical guide to Linux disk I/O performance tuning for homelab servers — IO scheduler selection for NVMe, SSD, and HDD, mount option optimization, real-time monitoring with iostat and ioping, and container IO throttling with cgroup v2.
Set up centralized NFS shared storage for your Proxmox homelab with Docker volume mounts, LXC bind mounts, and performance tuning — practical configs for backup storage, media libraries, and container data.
Replace cron with systemd timer units for reliable, observable homelab task scheduling — persistent schedules, real journald logging, monotonic intervals, and hardened service units with practical backup, maintenance, and healthcheck examples.
Deploy a lightweight WireGuard VPN server in a Proxmox LXC container — configure persistent tunnels, NAT routing, client generation, and firewall rules for secure remote access to your entire homelab network.
Harden Linux systemd services with built-in sandboxing directives — ProtectHome, ProtectSystem, CapabilityBoundingSet, NoNewPrivileges, PrivateTmp, and systemd-analyze security scoring. Includes real hardened service files for common homelab daemons.
Set up Caddy as a Docker reverse proxy for your homelab — automatic Let’s Encrypt HTTPS with zero config, reusable Caddyfile snippets, zero-downtime reloads, Cloudflare DNS-01 wildcards, HTTP/3 support, and production security hardening.
Configure a production-ready MikroTik RouterOS 7 firewall — understand filter, NAT, mangle, and raw tables, enable FastTrack for wire-speed forwarding, implement connection tracking state rules, and build brute force protection with dynamic address lists.
