Private flakes

On FlakeHub, private flakes are Nix flakes that are accessible only to users who are both authenticated and granted access to the flake.

Publishing private flakes

Like all flakes on FlakeHub, you can only publish private flakes from a supported platform. That currently includes:

• GitHub Actions
• GitLab CI

To make a flake private, set visibility to "private" in your publishing configuration.

GitHub Actions

Here’s an example flakehub-push configuration:

- name: Push private flake to flakehub
  uses: determinatesystems/flakehub-push@main
  with:
    visibility: "private"

GitLab CI

Here’s an example flakehub-push configuration:

stages:
  - "release"
 
include:
  - component: "gitlab.com/DeterminateSystems/flakehub-push/component@main"
    inputs:
      stage: "release"
      visibility: "private"

Accessing private flakes

Once you’ve published a private flake to FlakeHub, you can access it as a Nix user if you (a) are a member of the flake’s organization and (b) have been granted access to that flake.

All Nix users can access public flakes like Nixpkgs:

nix flake show "https://flakehub.com/f/NixOS/nixpkgs/*"

If you were a member of, for example, the organization super-duper-secret and granted access to the flake important-stuff, this would work for you:

nix flake show "https://flakehub.com/f/super-duper-secret/important-stuff/*"

Users not granted access to that flake, however, would see a warning like this:

Flake `super-duper-secret/important-stuff` not found.)
