Docker containers are being leveraged to manage Sauce Connect tunnels in order to automate and scale this solution. This approach is useful for managing multiple applications that reside in different environments, creating high availability Sauce Connect tunnels on the same system, or no longer wanting to manage Sauce Connect versions. The Sauce Labs Support Team maintains an open source Docker image of Sauce Connect in Docker Hub, which can be pulled and run using the `docker pull` command and additional environment variables set for authentication. This approach also allows for easy integration with CI/CD pipelines and GitHub Actions, enabling users to automate their testing infrastructure and improve scalability and flexibility.
