wait-for-workflows-action

This is an action to wait for all workflow runs of the current SHA.

Purpose

When any workflow has paths filter in GitHub Actions, we cannot enable the status check in a branch protection rule.

This action aggregates the statuses of workflow runs.

Getting Started

To wait for all workflow runs of the current pull request,

name: wait-for-workflows

on:
  pull_request:

jobs:
  wait-for-workflows:
    runs-on: ubuntu-latest
    timeout-minutes: 30
    steps:
      - uses: int128/wait-for-workflows-action@v1

Enable a status check

You can set up a branch protection rule with the status check of wait-for-workflows. For example,

Therefore, a pull request status looks like:

How it works

This action fetches the workflow runs against the current commit SHA. It determines the rollup state as follows:

• If any workflow run is failing, this action exits with an error.
• If all workflow runs are completed, this action exits successfully.
• Otherwise, check again.

It excludes the workflow of self to prevent an infinite loop.

It filters the workflows by the current event such as push or pull_request.

Exclude or filter workflows by name patterns

By default, this action evaluates all workflow runs. You can exclude workflow runs by glob name patterns.

jobs:
  wait-for-workflows:
    runs-on: ubuntu-latest
    timeout-minutes: 30
    steps:
      - uses: int128/wait-for-workflows-action@v1
        with:
          exclude-workflow-names: |
            * / generate-graphql

You can also filter workflow runs by glob name patterns.

jobs:
  wait-for-backend-ci:
    runs-on: ubuntu-latest
    timeout-minutes: 30
    steps:
      - uses: int128/wait-for-workflows-action@v1
        with:
          filter-workflow-names: |
            backend / *

Caveat

Cost of GitHub-hosted runners 💰

This action runs until all workflows are completed. It may increase the cost of GitHub-hosted runners. If your repository is private, it is strongly recommended to use your self-hosted runners.

GitHub API rate limit

This action calls the GitHub GraphQL API until all workflows are completed. It is recommended to use a token of GitHub App or PAT, instead of the default GITHUB_TOKEN. See rate limiting for details.
