# nixfiles
[![nodes](https://github.com/kittywitch/nixfiles/actions/workflows/nodes.yml/badge.svg)](https://github.com/kittywitch/nixfiles/actions/workflows/nodes.yml)
These are the NixOS configurations for my systems. I run nothing but NixOS on my hardware, aside from virtual machines.
## CI
CI for this repository uses [arcnmx/ci](https://github.com/arcnmx/ci) and aims to achieve two goals:
| Action | Purpose |
| --- | --- |
| [nodes](ci/nodes.nix) | Build and cache host closures, show state of host evaluability/buildability |
| [niv-cron](ci/niv-cron.nix) | Automatically update the dependencies used by the repository, cache them and host closure build results with them. |

## Commands
The commands here aside from the `nix build` command are provided through the shell. The `<target>` and `<host>` commands are runners provided through [arcnmx/tf-nix](https://github.com/arcnmx/tf-nix).
Please use `nix-shell` or [direnv/direnv](https://github.com/direnv/direnv). The shell is not compatible with [nix-community/nix-direnv](https://github.com/nix-community/nix-direnv).
| Command | Purpose |
| --- | --- |
| `nf-update` | Fancier `niv update`. |
| `nf-actions` | Updates CI integrations. |
| `nf-test` | Tests CI actions. |
| `<target>-apply` | Deploys to the provided target. |
| `<target>-tf` | Provides you a terraform shell for the provided target. |
| `<host>-ssh` | SSH into the provided host. |
| `nix build -f . network.nodes.<host>.deploy.system` | Build a system closure for the provided host. |
