GitHub Action: Workflow Run Queue

If the same workflow is already running from a previous commit, wait for it to finish

Why?

Workflows run on every commit asynchronously, this is fine for most cases, however, you might want to wait for a previous commit workflow to finish before running another one, some example use-cases:

• Deployment workflows
• Terraform workflows
• Database Migrations

Usage

.github/workflows/my-workflow.yml

jobs:
  xyz:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: ahmadnassri/action-workflow-queue@v1

      # only runs additional steps if there is no other instance of `my-workflow.yml` currently running

Inputs

input	required	default	description
github-token	❌	github.token	The GitHub token used to call the GitHub API
timeout	❌	600000	timeout before we stop trying (in milliseconds)
delay	❌	10000	delay between status checks (in milliseconds)
