# NixOS Proxmox k8s-base Template

This folder contains a Kubernetes-ready NixOS base config for your Proxmox
template VM build.

## Files

- `flake.nix`: pins `nixos-25.05` and exposes one host config.
- `configuration.nix`: k8s-base settings for Proxmox guests.

## Before first apply

1. Add `hardware-configuration.nix` from the VM install:
   - `nixos-generate-config --root /`
   - copy `/etc/nixos/hardware-configuration.nix` next to `configuration.nix`

## Build/apply example inside the VM

```bash
sudo nixos-rebuild switch --flake .#template
```

## Notes

- This pre-installs heavy shared Kubernetes dependencies (containerd + kube tools)
  to reduce per-node bootstrap time.
- Cloud-init still injects the runtime SSH key and per-node hostname/IP.
