rerun-workflows-action

This action finds the failed workflow runs and reruns them.

Getting Started

GitHub Actions does not provide a way to rerun the failed workflow runs of a pull request. We need to open the failed workflow runs and click the Re-run failed jobs button for each workflow run.

The below workflow reruns the failed workflow runs when /rerun is commented on a pull request.

# When `/rerun` is commented on a pull request, rerun the failed workflow runs.
name: rerun-workflows

on:
  issue_comment:
    types:
      - created

jobs:
  rerun:
    if: github.event.issue.pull_request && github.event.comment.body == '/rerun'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/github-script@v7
        id: get-head-sha
        with:
          result-encoding: string
          script: |
            const { data: pull } = await github.rest.pulls.get({
              owner: context.repo.owner,
              repo: context.repo.repo,
              pull_number: context.payload.issue.number,
            })
            return pull.head.sha
      - uses: int128/rerun-workflows-action@v0
        with:
          event: pull_request
          sha: ${{ steps.get-head-sha.outputs.result }}

For example, you created a pull request and the following workflows are triggered:

• ✅ microservice1-test
• ❌ microservice2-test
• ✅ microservice3-test
• ❌ microservice4-test
• ✅ microservice5-test

When you comment /rerun on the pull request, this action reruns the failed workflow runs microservice2-test and microservice4-test.
