How are Proxmox containers managed?

It uses the 'pct' utility via SSH to the Proxmox host, allowing for container status checks, power management, and command execution within LXC containers.

Does it handle non-containerized hosts?

Yes, it includes specific logic for bare-metal hosts like 'larussa', including post-deployment verification for NVIDIA GPU drivers and Podman services.

Why shouldn't I deploy dns1 and dns2 simultaneously?

DNS servers are critical infrastructure; the skill requires sequential deployment (dns1 first, then dns2) to ensure at least one DNS resolver is active at all times.

What deployment tool does this skill use?

The skill primarily uses Colmena to build and apply NixOS configurations across the infrastructure inventory.

Deployment & DevOps

Manages NixOS deployments and Proxmox LXC containers using Colmena and specialized troubleshooting workflows.

About

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

Automated Colmena deployment patterns for single and multi-host environments
Cross-host service monitoring using systemctl and journalctl via pct exec
Remote Proxmox LXC container management including start, stop, and reboot
Post-deploy GPU health checks and recovery workflows for bare-metal hosts
Sequential DNS deployment safeguards for critical infrastructure availability
15 GitHub stars

Use Cases

Deploying critical DNS updates sequentially to ensure zero-downtime for the network
Troubleshooting and recovering failed NVIDIA drivers or Podman containers on hardware-specific hosts
Updating NixOS configurations across a distributed Proxmox cluster without manual SSH overhead
