| It is possible to override the global Nix configuration set in your <code>nix.conf</code> file for the purposes of evaluating a flake. This can be useful, for example, for setting up binary caches specific to certain projects, while keeping the global configuration untouched. The flake file can contain a nixConfig attribute with any relevant configuration settings supplied. For example, enabling the nix-community binary cache would be achieved by:
| |
| {{File|3=<nowiki>{
| |
| ...
| |
| nixConfig = {
| |
| extra-substituters = [
| |
| "https://nix-community.cachix.org"
| |
| ];
| |
| extra-trusted-public-keys = [
| |
| "nix-community.cachix.org-1:...="
| |
| ];
| |
| }
| |
| }</nowiki>|name=flake.nix|lang=nix}}{{Note|If you are used to configuring your Nix settings via the NixOS configuration, these options are under <code>nix.settings</code> and not <code>nix</code>. For example, you cannot specify the automatic storage optimisation under <code>nix.optimisation.enable</code>.}}
