Add worker-1 (4 vCPU / 16 GiB) on shoryu, and worker-2 (4 vCPU / 16 GiB) plus worker-3 (2 vCPU / 8 GiB) on shushou, as microVMs. They come with a genK3sAgentModule and the per-host/output/home-manager wiring, and are labelled node-role.kubernetes.io/worker=true. The masters keep their control-plane:NoSchedule taint, so workloads land on the workers.
Library
This directory contains helper functions used by outputs/default.nix (and the installer flake) to
reduce code duplication and make it easier to add new machines.
Current Functions
Core System Generators
attrs.nix- Attribute set manipulation utilitiesmacosSystem.nix- macOS configuration generator for nix-darwinnixosSystem.nix- NixOS configuration generatorcolmenaSystem.nix- Remote deployment configuration for colmena
Specialized Module Generators
genK3sServerModule.nix- K3s server node configuration generatorgenVmHostModule.nix- physical VM host (bridge + libvirt) configuration generatorgenMicrovmGuestModule.nix- NixOS microVM guest configuration generatorgenLibvirtDomainXml.nix- libvirt domain XML generator (imported directly by host configs)
Entry Point
default.nix- Main entry point that imports the generators and exports them as a single attribute set, plus therelativeToRootandscanPathshelpers
Usage
These functions are designed to:
- Generate consistent configurations across different architectures
- Provide type-safe configuration for complex systems
- Enable easy scaling of the infrastructure
- Support both local development and production deployments
Architecture Support
- x86_64-linux: Primary desktop systems
- aarch64-linux: ARM64 Linux systems (Apple Silicon, SBCs)
- aarch64-darwin: Apple Silicon macOS systems
