Github Actions build canceller

A GitHub Action for cancelling old PR builds.

How it works

• Action is looking for workflows on current repo
• To limit in which workflows we want to kill old builds, you can use "worflow1|workflow2" as a value for workflow_filter parameter.
• Action is looking then for older builds that have status in_progress|queued on the different GIT SHA and kills 'em

GitHub Actions

# File: .github/workflows/shot.yml
name: build_canceller
on:
  pull_request:
jobs:
  build_canceller:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: shot
      uses: yellowmegaman/gh-build-canceller@v1.6
      with:
        github_token: ${{secrets.PERSONAL_TOKEN}}
        workflows_filter: "CI|pr"

This will automatically kill all old builds on this PR branch.
