Managing rollbacks with GitHub Actions and Heroku

This guide provides a comprehensive overview of setting up both automated and automatic rollbacks for a GitHub repository using GitHub Actions and Heroku. The process involves creating a GitHub Actions workflow, installing the necessary tools such as Python and Heroku CLI, and fetching the list of releases to determine the previous release version. For automatic rollbacks, a monitoring service like Papertrail is used to send alerts to a webhook, which triggers a GitHub Actions workflow to perform the rollback. The guide also covers setting up a FastAPI webhook endpoint to verify alert conditions and trigger the rollback process. By following this guide, developers can ensure their application can quickly revert to a stable state in case of issues with a new deployment.
