# Cachix for this repo
|
|
|
|
This repo's NixOS flake lives under `nixos/`.
|
|
|
|
The workflow in `.github/workflows/cachix.yml` can build the `strixi-minaj`
|
|
system closure on GitHub Actions and push the results to a Cachix cache.
|
|
|
|
## One-time setup
|
|
|
|
1. Create a Cachix cache (on cachix.org).
|
|
2. Create a Cachix auth token with write access to that cache.
|
|
3. In the GitHub repo settings:
|
|
- Add a repo variable `CACHIX_CACHE_NAME` (the cache name).
|
|
- Add a repo secret `CACHIX_AUTH_TOKEN` (the write token).
|
|
|
|
After that, pushes to `master` will populate the cache.
|
|
|
|
## Using the cache locally
|
|
|
|
Option A: ad-hoc (non-declarative)
|
|
|
|
```sh
|
|
cachix use <your-cache-name>
|
|
```
|
|
|
|
Option B: declarative via flake `nixConfig` (recommended for NixOS)
|
|
|
|
1. Get the cache public key:
|
|
|
|
```sh
|
|
cachix show <your-cache-name>
|
|
```
|
|
|
|
2. Add it to `nixos/flake.nix` under `nixConfig.extra-substituters` and
|
|
`nixConfig.extra-trusted-public-keys`.
|
|
|
|
Note: `nixos/nix.nix` sets `nix.settings.accept-flake-config = true`, so the
|
|
flake `nixConfig` is honored during rebuilds.
