There is currently no (easy) way to only enable a certain composite action step when some input is set, so just don't automatically install Nix at all.

# update-flake-lock
|
|
|
|
This is a GitHub Action that will update your flake.lock file whenever it is run.
|
|
|
|
> **NOTE:** As of v3, this action will no longer automatically install Nix to the action runner. You **MUST** set up a Nix with flakes support enabled prior to running this action, or your workflow will not function as expected.
|
|
|
|
## Example
|
|
|
|
An example GitHub Action workflow using this action would look like the following:
|
|
|
|
```yaml
|
|
name: update-flake-lock
|
|
on:
|
|
workflow_dispatch: # allows manual triggering
|
|
schedule:
|
|
- cron: '0 0 * * *' # runs daily at 00:00
|
|
|
|
jobs:
|
|
lockfile:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- name: Checkout repository
|
|
uses: actions/checkout@v2
|
|
- name: Install Nix
|
|
uses: cachix/install-nix-action@v14
|
|
with:
|
|
install_url: https://nixos-nix-install-tests.cachix.org/serve/vij683ly7sl95nnhb67bdjjfabclr85m/install
|
|
install_options: '--tarball-url-prefix https://nixos-nix-install-tests.cachix.org/serve'
|
|
extra_nix_config: |
|
|
experimental-features = nix-command flakes
|
|
access-tokens = github.com=${{ secrets.GITHUB_TOKEN }}
|
|
- name: Update flake.lock
|
