Goal

The goal of this project is two-fold:

• Enable users of dependabot to have a dependabot-like way to keep Cake dependencies up-to-date.
• To keep the code for integrating Cake as a new ecosystem in dependabot up-to-date and tested.

To that end, I have forked the original PR into a custom repo where I try to keep the original code from dependabot-PR 1848 up-to-date and error-free.

Install

Use the action in your workflow yaml by adding a step with uses: nils-org/dependabot-cake-action@v1.

Usage

- name: check/update cake references
  uses: nils-org/dependabot-cake-action@v1
  with:
    # Where to look for cake files to check for dependency upgrades.
    # The directory is relative to the repository's root.
    # Multiple paths can be provided by splitting them with a new line.
    # Example:
    #   directory: |
    #     /path/to/first/module
    #     /path/to/second/module
    # Default: "/"
    directory: ""

    # Branch to create pull requests against.
    # By default your repository's default branch is used.
    target_branch: ""

    # Auth token used to push the changes back to github and create the pull request with.
    # [Learn more about creating and using encrypted secrets](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets)
    # default: ${{ github.token }}
    token: ""

    # List of dependencies that will not be updated
    # Example:
    #   ignore: |
    #    Cake.7zip
    #    Cake.asciidoctorj
    # default: none
    ignore: ""

Limitations

This not a real dependabot, so there are no "commands" to give (like @dependabot rebase and such). If you need to rebase the PR, you'll have to do that manually.

Full Example

Save the following content in you're repo under .github/workflows/dependabot-cake.yml

name: dependabot-cake
on:
  workflow_dispatch:
  schedule:
    # run everyday at 6
    - cron:  '0 6 * * *'

jobs:
  dependabot-cake:
    runs-on: ubuntu-latest # linux, because this is a docker-action
    steps:
      - name: check/update cake dependencies
        uses: nils-org/[email protected]

Background

The original code was developed for dependabot/dependabot-core#1848 (a PR for dependabot/dependabot-core#733): To have dependabot check cake-references.

Currently dependabot has postponed adding new ecosystems and sadly merging dependabot/dependabot-core#1848 might take some time.

Idea / Attribution

Most of this was shamelessly copied from https://github.com/patrickjahns/dependabot-terraform-action/

Running Locally

It is also possible to run this action locally:

• Clone this repo

• build the docker image

  cd src && docker build -t dependabot-cake:develop .

• run the container and give the needed environment-vars

  docker run --rm -e DRY_RUN=1 -e GITHUB_REPOSITORY=nils-a/Cake.7zip -e INPUT_TARGET_BRANCH=develop -e INPUT_TOKEN=your-github-api-token dependabot-cake:develop

Cake targets

• Build-Image Creates the image.
  • imageName=some-image-name to set the image name. Default: dependabot-cake
• Run-Test Runs a container off the image locally. Settings:
  • --test-RepositoryName=owner/repo to set a repository. Default: nils-a/Cake.7zip
  • --test-RepositoryBranch=branch to set a branch. Default: develop
  • Environment variable INPUT_TOKEN must be set to a personal access token.
  • --test-folder=subfolder to set a folder to search. Can be given multiple times. Default: ["/"]
  • --test-no-dryrun if set, real PRs are created.
  • --test-ignore=Cake.7zip ignore a dependency. Can be given multiple times. Default: []

Alternatives

One alternative to dependabot is Renovate which fully supports Cake. See the post on cakebuild.net for a sample integration.
