This is a GitHub Action that will cancel any previous runs that are not completed for a given workflow.

This includes runs with a status of queued or in_progress.

When you git push, this GitHub Action will capture the current Branch and SHA. It will query GitHub's API to find previous workflow runs that match the Branch but do not match the SHA. These in-progress runs will be cancelled leaving only the latest run.

Read more about the Workflow Runs API.

Typically, you will want to add this action as the first step in a workflow so it can cancel itself on the next push.

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Cancel Previous Runs
        uses: styfle/cancel-workflow-action@0.6.0
        with:
          access_token: ${{ github.token }}
      #- name: Run Tests
      #  uses: actions/setup-node@v1
      #  run: node test.js
      # ... etc

In some cases, you may wish to avoid modifying all your workflows and instead create a new workflow that cancels your other workflows. This can be useful when you have a problem with workflows getting queued.

• Visit https://api.github.com/repos/:org/:repo/actions/workflows to find the Workflow ID(s) you wish to automaticaly cancel.
• Add a new file .github/workflows/cancel.yml with the following:

name: Cancel
on: [push]
jobs:
  cancel:
    name: 'Cancel Previous Runs'
    runs-on: ubuntu-latest
    timeout-minutes: 3
    steps:
      - uses: styfle/cancel-workflow-action@0.6.0
        with:
          workflow_id: 479426
          access_token: ${{ github.token }}

• Note: workflow_id can be a Workflow ID (number) or Workflow File Name (string)
• Note: workflow_id also accepts a comma separated list if you need to cancel multiple workflows

At the time of writing 0.6.0 is the latest release but you can select any release.
