Thoughts on homelab infrastructure, self-hosting, system administration, and automation.
Ansible's password lookup plugin was silently regenerating Zabbix PSK keys every time Semaphore ran the playbook, causing agents to lose encrypted connectivity. Here is the root cause and the fix.
Proxmox apt upgrades restart the networking service, detaching LXC veth interfaces from vmbr0. Here is the root cause and the permanent if-up.d hook fix.
How I wired up Claude Code to my homelab using Model Context Protocol servers for Proxmox, Zabbix, Semaphore, and UniFi - natural language infrastructure management that actually works.
How I built a workflow that uses a local LLM to analyze Zabbix alerts and send intelligent Telegram notifications - no cloud APIs, no subscription fees.
How I configured NVIDIA GPU passthrough for Plex hardware transcoding and Ollama LLM inference in privileged Proxmox LXC containers, including driver gotchas and VRAM limitations.
A deep dive into monitoring 18 hosts with Zabbix 7 - from PSK-encrypted agents and custom UniFi monitoring to Grafana dashboards and maintenance windows.
Learn how to expose self-hosted services to the internet without opening firewall ports, using Cloudflare Tunnel for enhanced security and DDoS protection.
A comprehensive journey through building a production-grade homelab infrastructure with Proxmox, Docker, and enterprise-grade monitoring.
How I use Semaphore as a web UI for Ansible to automate VM creation, onboarding, system configuration, and rolling updates across my Proxmox homelab cluster.
