Workflow run cleanup action

This action cleans up previously running instances of a workflow on the same branch. This accomplishes the task of automatically cancelling CI runs on pushes to the same branch, which is a common feature in most CI systems but currently not possible with GitHub actions.

Configuration

None. The action uses the GitHub action environment variables to obtain the workflow name and branch. You must, however, set the GITHUB_TOKEN environment variable:

Note: if you use a personal access token, ensure that the repo scope is included.

Example usage

uses: huf-mobility-solutions/cancel_older_workflow_jobs_action
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

You may want to disable this action from running on tags or master, especially if you have CD pipelines linked to your CI passing on every commit. In that case, something like this should work:

name: CI
on:
  push: []
  jobs:
    cleanup-runs:
      runs-on: ubuntu-latest
      steps:
      - uses: huf-mobility-solutions/cancel_older_workflow_jobs_action
        env:
          GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
        if: "!startsWith(github.ref, 'refs/tags/') && github.ref != 'refs/heads/master'"
    ...
