Manages NixOS deployments and Proxmox LXC containers using Colmena and specialized troubleshooting workflows.
This skill provides a comprehensive toolkit for managing a Nix flake-based infrastructure, streamlining deployments across diverse environments including Proxmox LXC containers and bare-metal servers. It enforces critical operational safety, such as sequential DNS deployments to prevent network outages and automated GPU verification for specialized hardware like the Larussa host. By integrating Colmena for configuration application and the Proxmox 'pct' utility for container orchestration, this skill empowers developers to maintain high availability, perform deep service troubleshooting, and manage complex server inventories through a unified interface.
Key Features
01Automated Colmena deployment patterns for single and multi-host environments
02Cross-host service monitoring using systemctl and journalctl via pct exec
03Remote Proxmox LXC container management including start, stop, and reboot
04Post-deploy GPU health checks and recovery workflows for bare-metal hosts
05Sequential DNS deployment safeguards for critical infrastructure availability
